    Thank you so much for this 😭

    Thanks for video! Is it possible to yield isophthalic anhydride in the same way?

    First step for Luminol, nice job

      Aussie Chemist or fluorescein

      I was going to make some luminol, should I make a synthesis video? I'll definitely do a chemiluminescence demonstration, but the synthesis has already been covered in several videos.

      If I had some resorcinol I would.

      Tom's Lab that’s true, I mean if the yield is reasonable I think it’s still worth posting, in fact, I’m planning to do one on luminol all the chemicals are on the way.

    Considering it's simplicity to get and its uses, this will probably be coming soon on my channel also.
    This was a very informative video. Good job!

      Yes, phthalic anhydride has a multitude of uses.
      Thanks! I try to make my videos concise but with a lot of information.

    What is the maximum percentage of yield we can get by this method?

    Make a video on phthalic acid

    How much phthalic anhydride can be made from 200gm of phthalic acid

    Has it any advantages for use as a dessicant?

    • @TomsLab
      @TomsLab  Před 6 lety

      Probably not. Because it dehydrates easily, the hydration is not very fast. It would be strong, but the time required is likely going to be too long. H2SO4 is probably going to be superior and you can regenerate it's drying capability by distilling off water.

    So it does not work with terephtalic acid ?

    • @TomsLab
      @TomsLab  Před 6 lety +1

      No, not with the tere or isophthalic acid isomers. The acid groups are too far apart and a bond cannot form.

      Tom's Lab but don't you think that there is close the carboxylic group of another molecule ? In theory a polyanhydride could form. I have to try.
