Turning Aspirin into Tylenol
Vložit

- This is a video that I've been meaning to make for a while. I think the idea of converting one drug to another is a pretty cool concept.
About a year ago, I made a series where I chemically converted Aspirin to Tylenol (aka acetaminophen, paracetamol, or APAP). The original series was spread out over several videos and was over 90 minutes long. It has a lot more detail, but it was a much bigger commitment to watch.

I'm an old-school chemist (PhD 1987). I love what you do, and it reminds me why I fell in love with chemistry as a teenager! Keep experimenting and teaching!
That's so cool! I love chemistry but didn't follow the profession... I have fun vicariously thru Nile
Dude I am kind jealous of any one who liked chemistry. I technically failed the class. Only because I never did my home work. I got nearly 100% on all my test. It just felt like all I did was balance equations.
Just curious and out of pure respect, do they use fetal tissue to make tylenol?
I love that you two found each other Marcus, this post warmed my heart. ❤️
@@shauntaebritt6488 no absolutely not
"I was able to convert 200 extra strength aspirins into one really weak tylenol"
SUCCESS
where did everything else go lol
Look at it this way if his yield was super high he might get in trouble with some farma companies ;) but that really depends on the pricing of both painkillers if it would even would be an issue
Yeah it is a success, simply because he did achieve he's goal. And it's pretty cool. And that would be great for chemistry students, either as theoretical exam or as practial lab for 4th semesters.
stonks
Cant spell success without SUCC so i guess he SUCCed some of it

Imma head out to buy a 30 pack of tylenol so I can have unlimited aspirin.

It's part of the chemical series between "organic side-shit" and "horrible tar"
saw this on the diagram and died lmfao
Ngl they should changed it to "fibrous elephant shit" for nomenclature
Sounds like it has alot more polymers for some reason
NileRed: The process is very straight forward
Me 26 minutes later: Wait what?
@Xypos I'm right there with you
Well if you couldn't follow the simple 327 steps in the process, I don't know what to tell you.
"Ah crap I got aspirin, not tylenol"
"Don't worry mom, I can work with this"
*Makes a very weak tylenol pill*
"Mom, I think you're gonna die"
Why the video was recorded:
hahahaha!
21:36 I thought "he's good... look, there's a Tylenol capsule in the product!" It was his stir bar.
The Tylenol was just a crusting on the stir bar, you'd have to swallow it whole to get any affect. lol

Converting a fresh big mac into a bk wopper

Underrated comment.
@@samarnadra problem is... Where to get a *fresh* big Mac.
@@samarnadra
Of course I meant that sarcastically. You simply can not use the word fresh for anything in a fast food restaurant.
That no country bans food says nothing about it's freshness.
@@samarnadra maybe you re confusing the word cold for fresh... LoL
It's true that some additives are allowed in some countries but not in others. "Yellow number 5" if I remember correctly.
You will find that sometimes even things like Mars bars are different in different countries. So yeah... They do replace one additive with another to achieve the same 'function'.... But that s still an additive... I would not call it fresh.
It's like when they put "fresh milk" on a pack of pasteurised milk, or "fresh juice" on a bottle of reconstructed OJ.
I think it's all legal to the letter of the law, but it's not what common sense says 'fresh' means.
I have to admit, I use your videos to fall asleep at night. Your voice is so soothing, calm, clear, and never talk too fast. You could narrate a bus schedule, and I'd buy the audiobook. I listen intently and usually before you're done, I am out like a light. But you are not boring! Thats how I discovered your channel. I actually watch the video again the next day. Thanks for your excellent channel!

23:12 "So my original prediction of 30% wasn't that far off, I just kind of misplaced the decimal by two spots" LOL
I watched the original videos a while back.
This was far less scattershot and easier to digest.
Of course this is the comment he would like. It reads how he speaks
i liked the crystals they looked like needles
next time someone asks me for a tylenol imma whip out my bottles of aspirin and my chemistry set and make it from scratch just to spite them
At least it will be a fresh batch of Tylenol. xD

Note: The "filler junk" is actually a carefully designed matrix that produces the correct dissolution profile and bio-availability of the tablet, whilst also ensuring proper binding, distribution of active in the matrix, good compression and ejection from the tablet press, etc., all without having a biologically active impact.
whatever you say NERD
So really cool filler junk
i believe you but that really sounds like advertizing bs lol
So you’re saying it is filler junk?
@@1e1001 the less "advertising" way of putting it is that the matrix is needed in pills so they don't just get eaten up in your stomach acid, and that they dissolve in the correct part of your body to treat whatever issue you're having!

I love these longer videos. They're so satisfying and fun to watch.
Rockabrand The feeling it's sooo fricking mutual !!!!
It's fascinating to watch those beautiful reactions... problem is when you do it at home it just becomes a total mess (crap as NileRed calls it), if you know what I mean. ;D Basically one step gets f-ed up, then the rest is just a waste of time.
I've seen you before...
This is really cool.
As a reference to reality, you created a 210mg rough equivalent of Tylenol?
That's wild.
This is so interesting. I wish I had paid more attention in chemistry
Same but then again in my school the only teacher was a nearly 60 year old witch that was seriously scary (she had mirrored glasses so she could see us students when writtting something on the board) and made chemistry super boring of a subject :/
@@Blutwind Reminds me of my current chemistry teacher. About 60 year old as well, can't control his anger, and the only thing he gave us to learn so far is texts that are just barely about chemistry that he has turned into these weird concentration practices that are basically just fusing every sentence together and he wants us to write it *perfectly*, and god help those who have a typo that he rates as "stupid". He then lets us write a test, and that's the content of his lessons.
He also likes to shout so loud that you can hear it rooms across and he likes to smash objects against furniture (or furniture against furniture) to release anger. I'm glad we never have access to chemicals right now. I wouldn't want to be in a room with him handling corrosive or toxic substances, he'd probably throw it across the room.
Oh yeah, he also doesn't like textbooks, so we write down hundreds of pages from his DIY text book (aka incoherent texts as mentioned before). Originally, I was happy I was finally getting chemistry lessons, but I have deep regrets for that wish.
Eh, home chemistry is much better anyway.
You only learn this kind of skills in Organic Chemistry class or lab.

I’m allergic to Tylenol
Let me get my tools
Same here, last time I had taken Tylenol I was covered in red rashes from top to toe. Wasn't a fun 2 weeks.
u sure ur not allergic to the red dye in the type or a filler material?
I had an allergy test done for acetaminophen and it was positive, so no.
@@joygao4656 if it was the filler material there allergic too they'd likely have issues with more drugs. since atleast to my knowledge the filler is almost always the same, atleast it is for each brand.
3:48 you should be aware that this is a yield of 94g of a mixture of ASA and salicylic acid. The recrystallization step almost certainly hydrolyzed a substantial amount of your product, not just a few percent. You can confirm this by using the iron (iii) chloride test for phenols. You will obtain a colored adduct with your recrystallized product, confirming the presence of a phenolic hydroxyl group. I know this because I synthesized ASA from salicylic acid and acetic anhydride, and after quenching the reaction mixture and decanting the precipitate, the crude product was recrystallized from boiling water. The melting point was extremely broad, strongly depressed, and was dependent upon the rate of heating. The NMR spectrum was a mess but did demonstrate the aromatic protons around 7.2-7.24ppm, and FTIR showed a broad and intense absorption around 3300/cm, and a sharp, very intense peak around 1710/cm.
This is all immaterial, however, since your next step is to hydrolyze any remaining ASA.
What
thanks to the last sentence, i can summarise as follows: “”
the crystals looked cool
they were needle shaped
Thank God for CVS, if I had a headache and needed to go through all of this for Tylenol I’d have a migraine or a brain tumor before I was finished.
Ive learned more about chemistry from your channel than I did from seven years at school with a shitty teacher. Thanks man.
Do be careful with the phenol. It's quite hazardous: Around a tablespoon on the skin can be fatal, and the burns it causes are painless so you may not notice that you spilled it on yourself until it's too late. Another concern is that trying to wash it from your skin with water tends to just spread it and increase the area of skin that is damaged- you must instead wash it off with glycerol or a solution of polyethylene glycol. I certainly wouldn't handle that stuff without a lab coat on!
Thank God you said something man, I think you saved his life
I very occasionally work with phenol in the lab I work at so this is actually helpful to know, do you know if it has the ability to move through nitrile gloves? Or do nitrile gloves adequately protect you from it?
Hey, I'm fairly new to your channel but I fell in love with your content. You make some pretty awesome videos and I genuinely enjoy watching them. I also appreciate how, for someone like me who doesn't really understand the science behind the experiments that you do, you explain every step of what's going on so everyone can follow along with what you're doing and that's great because otherwise I would not be interested and wouldn't really know what was going on in your videos. Thank you for explaining the science of your experiments for people like me. I am interested in what you are doing but I don't really know the chemistry behind them so for you to explain it for us, keeps me interested and I always learn something new from watching you. I love your channel and your content and you genuinely help me to not only appreciate science but help me to like it and keep my attention and I actually really enjoy what I'm watching, so thank you.
You are awesome Nile! I'm so happy that you are succeeding with CZcams!!
Thanks!
I watched the orignal series like 2 or 3 times , but one video covering the basic reactions is pretty nice as well.
I think you should do this always: a while after ther series combine it into an video
Finley Franke YAAAAS PLEASE !!!!
Your channel has sparked a great intrest in Chemistry with my children and I. Seeing how things connect when you find pathways to connect them. Absolutely brilliant
Your channel has definitely reinvigorated my interest in chemistry. Thanks!
The art of turning 200 aspirins into 1/2 tylenol :)
For real now, I have a love for chemistry and your videos are pure candy. The right equipment properly used, apt explanations pleasantly delivered, good quality camera, camera work and cuts makes it a joy to watch. My average patience for youtube vids is about 7 minutes, yours watch like professional documentaries. Your videos are excellent fodder for chemistry students.
What I find particularly elegant and alchemistic is that your subseqjuent videos keep transforming molecules made in earlier installments, highlighting the dance of functional groups that is applied chemistry. Every molecule can be an end point, starting point and intermediate. A pleasure.
Neat! Whenever I want to turn my aspirin into tylenol, I just pour some mor into the tylenol bottle.
But you're method is much more impressive. Keep up the good work.
I'm taking Orgo 2 at university right now and we are basically learning different reactions and mechanism. I'm now re-watching all your organic synthesis to see how much I can recognize. This honestly is amazing to me being able to come back and thinking how and why you came up with your reaction pathway or possible side products.
I personally hated chemistry in school but this is just so interesting that i regret paying so little attention to it in school. Thank you !!!
So there's a kind of coffee maker that used to be used a lot more, called a vacuum pot, which is essentially a self-contained vacuum filtering setup for extracting coffee. It's crazy to me how much a vacuum filtering device like the one used here looks like it when the flask is attached.
Basically it consists of a flask-like carafe and a filtering bowl that has a long glass tube that goes down into the flask, with a rubber gasket between the two and one of various kinds of filters in the bottom of the bowl. Water bubbles up into the top where it is mixed with coffee, and eventually air bubbles out through the tube too and is not replaced. With the proper timing, you can develop a really good low pressure environment inside the carafe that sucks the water right out of the coffee grounds as the carafe cools. It's especially cool watching water boil below 100 c in the carafe, if you get the pressure low enough.
I'm totally intrigued and I googled "coffee vacuum pot" and got: "The vacuum pot, also called the syphon, is a beautiful and flashy way to make great coffee. Invented in Germany in the early 19th century, it's a full immersion brewer that also employs a metal or cloth filter, so you end up with a full-bodied and clean cup. "
is that the device? There are some new models for purchase for under 100 bucks!
@@kayjay7585 Yes. But I use the kind with a glass filter rod. It's hard to explain what that is but essentially it's a glass rod with a bulge in the middle, and that bulge is covered with bumps or burrs. The rod is held down by suction and the bumps make contact with the bottom of the filtering chamber, forming a coarse filter that allows quite a lot of liquid to flow past it but not medium-grind coffee.
The cheap models have a reputation for being fragile. Mine are both 1950's and more resilient. I plan to give them to my children if I ever have any.
Would you make a series of Flavor and Odor making videos? Love your channel!
I plan to
Amazing! Thanks for the great work
Seconded! I’d be definitely interested to learn some general tips for esterification especially ones that don’t use the alcohol also as the solvent.
Ingredients: aroma

Man, I love your videos. I have always loved chemistry and physics, and ironically, i dropped out of chemistry just due to my attention to 3D CAD/CAM and physics and now photography, and just not able to dedicate the correct amount of time to chemistry that it deserves. Thanks for all you do. I really enjoy seeing your work.
Reminded me of my chem labs. Loved watching and guessing your next steps without stressing for any upcoming exams lol
I feel like regardless of how much you love Chemistry, the clean up sometimes makes it feel like it isnt worth it
17:30 That flask looks so pretty with all those greens!
your videos are really calming for me somehow. And i learn a bunch about my favorite kind of science along the wayy so perfect combination. Thank you for doing these videos! :) they help a lt especially now
Really cool. A video of full chemical synthesis will all the steps and difficulties described. Thank you, as a person who's very interested in that.
as a pharmacy student, i loved this video. it's so cool seeing the structure change.
When I want to convert my aspirin to tylenol, I just bring my receipt back to CVS and they swap it out.
That's one is the one of most lovely project, NILE RED.
Fair play to you with so many steps involved!
I think you should do the Caffeine as a single video, no matter how long it is, I think it’s nice to not have to deal with the wait time for slow internet(which I have half of the time)
And this is why I do inorganic chemistry... :P QUANTITATIVE YIELDS!
This takes me back to organic chem lab. Love your content, keep it up!
This was seriously fascinating, I’m amazed by how things are converted.
Great video. Here's a couple of points that could be useful for improving the method:
(1) I've seen some sources suggest that deprotonation of salicylic acid aids decarboxylation due to the competition for the proton. This should also stop the esterification as the carboxylate is not electrophilic.
(2) Before nitration, protect the phenol with either acetic anhydride or (acetic acid + HCl + boil). Do the nitration using c. sulfuric acid as the solvent, and 1.1 equivalents of NaNO3, at -5 degrees Celsius (ice/brine bath), then hydrolyse. It adds two steps; however, this will lead to a selective mononitration to p-nitrophenyl acetate. Also means you avoid forming nasty di(-) and trinitrated products, which will be explosive. Work it up by pouring it onto ice and water and filter in vacuo. The crystals you get out will be almost exclusively p-nitrophenyl acetate.
(3) The decomposition of p-aminophenol is due to oxidation/polymerisation in light, but it actually amounts to very little (if you check by NMR etc), so long as you keep it out of solvent. Recryst. from water is the usual way of purification, but I found that toluene works well too (if you can get your hands on it).
(4) Recryst for p-aminophenol should be easier than for paracetamol.

As much as i hated chem in school, i love watching your videos.
This was interesting to watch. I graduate in May with a B.S. in Chemical Engineering, and my senior project is designing an acetaminophen plant. I didn’t end up getting phenol as a raw material but I know people who did.
Watching a video like this makes me want one long ass video of you just cleaning all your glass after a project.
Request: If you are going to do a long and complicated synthesis chain like this for caffeine, but don't want to do a lot of your normal high production value videos, could you make a B channel where you upload lower production value deeper dive videos for each step as you go?
You are probably correct that a summary like this is of more interest to most of your viewers, but the 90+ minutes of your original series seemed to have a lot more reflection on what went wrong where and how you might want to do it different or why you did it the way you did, which is very useful and/or interesting information for some of us.
Outside of north america Tylenol is more commonly recognized than acetaminophen. Having grown up in Texas, I default to the generic name and over the last year I have needed to purchase it in Mannheim Germany, Cork Ireland, and Santiago Chile. In all 3 cases the word "acetaminophen" was not recognized but the word "Tylenol" was recognized when I asked where to find it (although in Santiago that was likely a result of Tylenol having a more standardized pronunciation globally).
You should had tried with paracetamol, it is more likely to be called that way.
Thanks, next time I need some will try that.
Well at least in Venezuela , we ask for acetaminophen or paracetamol. Tylenol is also found but it's not as common as the other two.
In Germany I have only ever heard of paracetamol
Trabber Shir Yeah, usually paracetamol is most recognised
Twas the night before Christmas, when all through the *house*
Not a creature was stirring, not even a *mouse*
Yet one thing was stirring, twas NileRed's low yield Tylenol *crumbs*
Ha-ha-ha
Damn ouch 😂
The purple tint of the p-aminophenol solution violently brought back memories of me developing with Rodinal and the color change of the spent solution
"Even though I do stuff like this all the time, it still blows my mind that it's possible to systematically build and degrade things on the molecular level."
And this is, I think,, probably the very most basic essence of most people's interest in chemistry. It's mine, anyway. Chemistry like this is essentially a kind of microscopic engineering combined with the performance of what feels like microscopic magic tricks, except you perform them for yourself as opposed to the _macroscopic_ card tricks you'd perform for others.
Actually doing organic chemistry like this almost feels like you're playing god in a small way, like these things shouldn't be possible and it's incredible that the possibility even exists, let alone that YOU get to just play around with it and have fun with it AND get paid for it, if you're extra lucky.
And this is why I want to study Chemistry when I get to Uni!
@@andrewflannery5790
Best of luck, mate. The only advice I'll offer is to ask you to please, be CERTAIN to attend a university with a good chemistry department. I got into the University of Queensland, which is one of the top 50 universities in the world. My degree (BSc double major in Chem) was both fun and interesting, but above all, the labs were astonishingly well stocked. So we got a LOT of top-shelf experience before ever leaving university.
this is how I'll get ahead on my Chem class. no joke, I love these videos.
That was very fun, thank you kindly!
I love this video!! I know its extra work but by any chance in future videos could you show all the steps taking place in a reaction such as the push of electrons? I'm taking Organic chem now and would love to use your videos as a way to better understand the subject matter!!
24:41 Why I watch your videos, even though, a lot of the times, I don't understand it.
next video:
"turning Pseudoephedrine into crystal meth"
no disrespect; i love your videos. this one in particular though i’ve been putting on to fall asleep every night for the last week. it knocks me out like 3 minutes in every time. i like to think that eventually i will learn something.
I'd like to see what kind of yield you would have if you just started with pure phenol.
Great video, I always enjoy your stuff!
im studying organic chemistry its fun to watch things happen instead of cramming reaction :P
I'm curious about your cleaning process. How do you clean everything?
Look for his other chanel, NileBlue. He post clean up vids there.
As someone who takes migraines medications that has APAP in them, this was a fascinating watch! Thank you 💖
Just had a mental breakdown check. Just wanna let you know, your voice is very comforting to me. i dunno why, but it is.
I've made aspirin before, or ASA to be precise. At some lab. ended up being pretty high purity. Couldn't take it back home though, but was about 10 grams yield or so.
I could collect more than that in a nature walk at my local park.
If you're talking about willow bark, that contains salicylic acid only, not acetylsalicylic.
yup. demoniack is right. You can make ASA from salicylic acid, but you'll have to also add Acetic anhydride plus some catalyst. ASA is superior and i don't think theres any ASA found in nature(not to my knowledge anyway).
If its a pain reliever and I were using it for that function then why would I care about the details? I know it works, I've used it.
You pop out to collect willow bark when you have a headache?
I never knew aspirin is not the same as paracetamol. In The Netherlands we often use the words interchangeably meaning the same thing, which is probably paracetamol.
hmm interesting. Yeah, definitely not the same thing. If they were, this video would have been way shorter :p
Here in Italy tylenol is known as Tachipirina, while Aspirin is, well, Aspirina.
They're definitely not the same drug, although in a pinch they can be used somewhat interchangeably as they both have antipyretic and antiinflammatory properties.
propably because people are just like "does someone have an aspirin", meaning they have a headache, so someone hands them a paracetamol pill, which does the same job
Also aspirin is relatively safe for hangovers but paracetamol definitely not.
Tylenol is not in the NSAID category of drugs and does not have anti-inflammatory properties. Just an FYI.
At college i had a quite similar project. We were suposed to convert Phenol into p-iodinenitrobenzene. It was really thirlling and fun. But at each step we had to do NMR and cromatography analysis. The yield can be easily low if you mess up on the purification steps. Watching your video and hearing that you're only doing this for fun, it's really amazing :]
Nitration first then convert the OH to I?
@@AlldaylongRock yeah, but since we want the nitro group to add at the para position, we first acetylate de OH group to block de orto position, nevertheless we got some o-nitrophenol though but in small amount.
So I really liked this video. I am a software developer and I find myself gravitating toward chemistry all the time now. Excitingly, this video produced so many questions along the way for me. One thing that stood out here was you speaking on a “pathway”. Could you do a video on a sort of overview as to how a process is designed. Where you have an idea. You write out a pathway and then consider the steps INCLUDING the necessary surrounding process or cleaning up the tools and disposing the waste behind you?
I see im a year late and you probably figured this out by now... but if you take a year of organic chemistry at a university, you will learn all the reactions used in this video and practice making synthesis pathways by being given a substrate and a product and telling what reactions you need to use to get there. Just a matter of knowing those reactions well and what they can accomplish.
Would love to see you explain how a flame less ration heater, like from an MRE, works then make one of your own.
That's a super simple reaction. It's just oxidizing a ton of really fine iron shavings with water. Basically, the fineness of the iron shavings means tons of surface area, so the reaction can happen really quickly. You're making a bunch of rust happen really fast, and rusting is exothermic so it gets hot. Bingo-bango, you've got hot food.
goddamn this gave me a headache, can i have that paracetamol
I love the subtle Nile-ism in these videos
Wow, that NMR it's amazing
Did you change your mic? Good video i enjoy watching your work!!
I was about to ask the same. At some points he sounds a bit different. I thought it was just his voice maturing, but it could just be the mic :)

Fascinating! Although, if I get a headache, I'll just take the Aspirin. 😁
No idea what I was watching, but super excited to see that you did it.
Wow, I hope you didn't get a headache from this project!!! I love listening to your voice!!! Purple Chrissy
Seems like a lot of your bigger losses come from doing things the “easy route” or getting somewhat lazy or sloppy, also using unrefined chemicals (i/e drain cleaner). How about revisiting some like this one, but using either purified or lab grade chemicals and also not going the easy way? Also doing some additional math and using correct amounts of water for things like recrystallization. It would be a pain, Im sure, but as of yet, you are probably one of the better chemists Ive seen on CZcams, and also it seems you like to teach. It would be awesome to see a synthesis like this come out as close as possible to theoretical. Keep it up man!

Oh yes, I would absolutely love that too! I think a new attempt could do the goal justice and get a much better yield. Although it was still fun to watch, it would be more satisfying to have a few more grams of product.
could you have kept it as an ester instead of a phenol when you added the no2 group so the ortho position would be sterically hindered so the reaction further favored no2 addition at the para end?
You just made a bunch of chemistry concepts click for me. Fantastic video.
I don't know anything about chemistry. But what I've learnt from watching you is re-crystalization always messes up the yeild. And that you always do it.
This was great. The nitration step is terrible. Still gives me nightmares from my old classes.
i also got ptsd from my old classes
Yeah that step was total crap, but he did mange to clean it up with activated carbon. ;D
7:43 "polymerized crap" lmao
chemistry is really cool, with the solubilities and stuff. normally someone thinks "it's dissolved in water it's gone now"....but you can mix in other stuff to make it precipitate out
I did organic synthesis research in undergrad with Oligosaccharides and it was a lot of fun! I had no interest in a career in it, but it was a wonderful learning experience!
