After watching like 50 of your videos I finally have a useful suggestion: Don't use candles as your paraffin source. There are weird (cheap) formulations used in candles that often contain residues of all sorts of things including perfumes used in the same molds. Just buy a block of canning wax to be sure you have purity. It's cheap.

😂 I’m so glad I’m not the only person that thought “does the candle need to be blue”?
If you calculate the H2S content you need and only put in enough sulphur for three or four equivalents, you can add an excess of wax to make the cleanup easier. Once your reaction is done, just heat to the melting point of the wax and then pour the rest of the wax out. You can reuse the wax if you really want to, as long as you don't use a literal burnt stick for a nucleation site lol. Should also stop the sulphur fouling your precious precious Claisen Adapter (and everything else).
Is he rich enough to get 4 blue candle sticks?
I remember taking a safety course (H2S alive) for working in the oil field. Apparently one of the scary things about H2S is that if you get exposed to a lethal dose (even without a knockdown), it might not kill you right away. So you may think you're fine, but it can build up in your system because it'll dissolve in your blood and then later that night or the next day your lungs start to fill with fluids and shut down due to damage from the gas, and that's what will kill you. Really nasty stuff, the instructor who was teaching this stuff was very adamant that there was no "safe" exposure limit to H2S despite different regions having "safe exposure levels". His argument was that you take a look at the regions that have oil and gas industries, vs the regions that don't, and the regions that have these industries "for some reason" have a higher safe exposure limit than regions without this industry.

Since carbon and sulphur already are elements I demand that Blue candle receive an "ad honorem" element status.

@@bagniacz3264 haha spot on 👌
I made a whole bunch by using a protein skimmer on my saltwater aquarium. The bacteria in the skimmer started churning it out one day and when I took the lid off to figure out what was making the smell- blam, the whole house smelled like rotten eggs. I laid on the floor, scrubbing out the protein skimmer and tank having very little idea that was actually dangerous and not just known-to-the-state-of-California-dangerous like I'd assumed. The smell is fucking gnarly.

"For our sulfur we just have... Sulfur"
Very informative, 10/10 would watch again
DnD idea attained. One blue candle, sulfur, and some charcoal from last night's campfire. Lizardfolk hold breath for 15 minutes to make it and to deploy it, and they also know when to leave it before everyone else, as they are more sensitive to the smell.
Here in Germany you can actually buy pre-made pellets that you can heat and generate H2S. They are called "Sulfidogen". They can be easily homemade:
25 parts by weight of paraffin oil are mixed with 15 parts of sulfur, then it is melted on the water bath. 7 parts of kieselguhr (very fine SiO2 basically, the same you can use for filtering, then its called "Diatomaceous earth" I think) are stirred into the homogeneous melt. The mass is brittle at room temperature, but plastically deformable at approx. 40 ° C. Small portions can be pierced with the cork drill.
This might be cleaner to work with and make less problems. Also, maybe less heat is required as they use already liquid oil instead of wax.
What are they sold for?
@@ipodhty I cannot say for sure, I think as an individual it cannot be purchased. However the manufacturing is easy, and they say at 170 C, 0,5g of the mixture releases 120mg H2S. So calculation is easy as well
We have a lot of yellow here, alchemy-ish reactants, stinky poisonous gas and potential fire hazard. Nearly perfect. I couldn't ask for more, really.

Yep, the inside of a woodshed is where I prefer to do my exothermic reactions as well.
Maybe add some glass wool in the neck of the flask to stop sulfur getting in the condenser. I also wonder if parrafin oil would do the same with easier cleanup.
I think it might actually, that's a good thought. Although I'm not sure it would 'turn off' as easy as it won't solidify and completely stop the reaction very well maybe
I'd give it a try in a test tube but I don't feel the need to stink up my lab :) Would be awesome if the temperature controls the production rate then
@@ExtractionsAndIre Measure the temperature at which it starts generating?
I do suspect that the reaction temperature if used with paraffine oil could be a bit lower.

“12 grams candle” was way funnier than it should’ve been. And yeah I’d stick with argon for the next run if it’s not too much of a pain. You’re likely right, with enough air you’re below the flammability threshold, but why risk it and/or rely on your small air pump and hope you’re below the threshold of your air/HS glass shrapnel bomb detonating
Wouldn't nitrogen gas be a better choice in this case? It's much cheaper than argon gas as far as I'm aware
regarding cleaning the flask: at uni when I made sulfur chlorides once, I used salt in ethanol as an abrasive to get most of the yucky residue out. fill it in, stopper, shake the hell out of it. got the idea from an online guide on how to clean tarred up bongs. ;)

Wow, that brings back memories. I evacuated our Jr. High School when I was in 8th grade (US) in the '70s, heating paraffin and sulfur in a test tube over a Bunsen burner in the science class. I found the procedure in an old book I bought at a university "get rid of old books" sale. I just wanted to make "smell of rotten eggs" 😬.
Lol oops
One professor told me safety advice that I carry with me always, and it's somewhat applicable here. The gist was that if you get that feeling coming from your subconscious that you're being unsafe, you should listen to it. Because mammals are well-evolved to develop patterns to predict future survival situations. Considerations to safety and building that survival sense is never a fool's pursuit.
The woodworking version is “If an operation feels unsafe, it probably is.”
Your video quality as in the quality of the overall product has come so far in just the past year or two even. Seems professional in all the right ways while still holding onto that boyish charm we’ve come to know and love
I used H2S liquid as a sulfur donator when I was growing MoS2 on Graphene (i also grew the graphene and transferred it onto silicon wafers) because the ATTM (Ammonium tetrathiomolybdate) reaction sometimes wouldn't happen. I used a PARR vessel to create high pressure temperatures which drove the reaction. The whole goal was to show that if the MoS2 seeded properly and grew on the graphene, the graphene could serve as the electron transport layer in a Hydrogen Evolution Reaction. which it did. Point being, H2S is the most putrid rotten egg smell i have ever had the pleasure to work with.
I did notice that in one of the shots of your reaction there were distinctly large "bubbles" of gas forming, but i think the surface tension of the molten liquid was very strong and trapped it. The clip where you had a burst of gas was when 4 or 5 of those "bubbles" burst open. So i think that you could safely say that this generates a ton of H2S immediately, but because of that surface tension it traps it until there is enough heat to break the tension and then it releases the gas that accumulated over time.

Somehow this has been one of your scariest videos lmao. The sudden kind of explosion at 9:26 was something that would have made me shit my pants while in uni. Also 100% agree, using a carrier gas is really nice in a case like this but I would definitely not do it with air again, especially considering that the reaction was kind of a bitch to handle properly. Cheers
If you want to find out whether the oxygen/H2S mix is dangerous would be to find out the rate at which the H2S is produced, i.e. by measuring the pressure in the reaction setup whilst the rxn is running.
With that you could probably calculate some type of steady state concentration based on your carrier gas flow rate.
Also, technically, just pumping the carrier gas at ludicrous speeds would give you the lowest concentrations, so you'd probably end up with a safer mixture at higher carrier gas pressures
RE on your sense of smell getting oversaturated when the concentration is too strong. The same thing happens with most geiger counters when you measure the radiation level: when it gets too high, they completely stop counting pulses because pulses become just a continuous internal discharge that does not produce impulses or sound. If you ever encounter that, you know you fked up.
What a weird method for making hydrogen sulfide, really intriguing. I usually make hydrogen sulfide by boiling sulfur and sodium hydroxide followed by acidification with hydrochloric acid, super easy and to my surprise, a very easy cleanup, so long as you use excess sodium hydroxide that is.
Ahh, but his method seems to produce anhydrous Hydrogen Sulfide.
That is probably useful in some cases. (I don't know enough chem to even begin guessing if that make a difference).
@@The_Keeper Yea, I guess but most of the time for me it's not necessary, fair point though
If your chemistry goes yellow, chuck some charcoal in there and you'll be fine
This is a very nice method for making H2S, which by the way is a gasotransmitter apparently, like NO. You could make pellets out of wax, sulphur and carbon, maybe a couple of grams each. And melt one pellet at a time when you need H2S. And you can after some tests add different number of pellets depending on how much gas you want to make
really nice of you to show the bong- i mean reaction flask- cleaning. hygiene is important on repeated use of glassware :)
A couple guys on a job at a refinery died to h2s because someone didn't torque a flange properly.
Favorite Australian chemist on yt
Nose can get used to low levels too. I was distilling liquids some time ago and it had a slight hydrogen sulfide smell (nothing for me to get worried about, a very slight smell). However, after long time sitting by and taking fractions I got slight sympthoms that turned into light head ache, moved to fresh air and it turned into a large headache followed by dizziness. For large concentration it can make you not smell it almost at all.
I'd rate H2S closer to cyanides in danger (I can possibly disable you pretty quickly too). The difference to me is that at least you can smell it unlike CO or if you're like me, HCN at least in slow levels (but yet high enough to give slight dizzyness).

I think this is a common reaction that should occur with any hydrocarbons, i remember visiting a gas desulfurization unit from a natural gas producer where the molten sulfur had still some methane/ethane mixed in and it produced quite a lot of H2S.
Also worth mentionning it also produced a strange mineral they called Carbsulf (not much info about this) which i assume was some kind of carbon polysulfide, it was somewhat translucent and flaky (i still got some in my collection).
In the discord, I had theorized that using walnut shell-based sand blasting media could be used to clean glassware. Basically dump some in and shake it up a bunch. Doesn't scratch it, is disposable, still abrasive and is generally quite dry. Could even use it in conjunction *with* water. Figured I'd mention it here just in case it makes a difference and maybe if people agree it'll get noticed? In the states I got like 10 lbs for something like 20 freedom bucks and 10 lbs of dry ass walnut shell is quite a lot more than I realized.
edit: Also maybe use a cheese grater for the wax/charcoal next time so you dont end up accidentally pulverizing it lmao.
This is such a cool and simple reaction. I’ve always wanted to see someone attempt it when I saw it listed as an alternative way of producing H2S on the Wikipedia page for hydrogen sulfide
i learn so much when i watch these vids. i had never even heard of a re-juicing gas before.
Love your cleaning tool of choice. You know what they say - everything's a hammer. Unless it's a screwdriver, then it's a chisel.
PRobably, the H2S reacts with the O2 in the air current to make H2O + the yellow Sulfur found in the rubber tube endings and/or top of the "air condenser"
