      @@michaelwerkov3438 The anhydride is hard to get since it's used to synthesize heroin.. In small amounts it'd be in something like aspirin synthesizing kits i believe. But you can have similar results or just a little less potent with just acetic acid & some catalyst I believe. There's also a plant that you can make the anhydride of, perhaps all of it is made from plants. I find this stuff interesting, I wanna study chemistry now and learn to do acetylation of a certain product..

    • @frostchem
      @frostchem  2 года назад +2

      I probably let some kind of impurity collect in the receiving flask but a normal simple distillation should be good enough to purify it. Acetic anhydride boils at 140°C so you want to collect the distillate at that temperature.

      @@allenhonaker4107 It really just matters on what you're distilling/heating. Substances like HCl, Bromine, Chromyl Chloride, etc. always want to find a way to escape its container. Those substances can eat away the silicone grease. Concentrated sulfuric acid is resistant against those substances and is used as a grease when distilling/heating those substances. If the substance isn't really as reactive as the substances I listed, you could just go ahead and use silicone grease. You can correct me if I am wrong.

      The cheapest and easiest way I know as of now is the reaction of sulfur monochloride and anhydrous sodium acetate. This is a video showing the method: ruclips.net/video/OrZ5Oa9K1R0/видео.html&ab_channel=LabCoatz . Sulfur chlorides are nasty and dangerous compounds so you should only attempt doing that method if you have proper precautions and safety.

    • @frostchem
      @frostchem  Год назад +1

      Acetic anhydride is basically just 2 acetic acid molecules bonded together and all the water molecules are removed. It wouldn't make any sense if you were to make an anhydride by adding water to the substance.

      I use Google translate: yes, there is an anime dr stone and in one episode they make sulfanilamide, where they mix chlorosulfonic acid and acetanilide to make the antibiotic, and I'm going to make a video explaining how it would be done in reality life, but I didn't find anything on the internet and no video on youtube explaining how to do it

    • @frostchem
      @frostchem  2 года назад

      I definitely know about Dr Stone! It's my most favourite anime. There is actually a video series of a Japanese chemist synthesizing it from benzene. Here is the video of him doing the last step in the synthesis where he reacts chlorosulfonic acid and acetanilide: ruclips.net/video/0HgB54fmSeA/видео.html&ab_channel=レイユール
      It might be very hard to understand the reaction as he is speaking in Japanese so
      I will also send a link to a image which shows all the steps of the synthesis: media.cheggcdn.com/study/0db/0db3b7c0-251e-4791-bf36-144986d55189/13112-21.2-2EEI1.png

    Acetic anhydride is no precursor to heroin. It is used to acetylate morphine into heroin. The precursor is morphine and not acetic anhydride. A precursor is a substance that can easily be converted into another without having to go through a complete synthesis. I would love to see how you convert acetic anhydride into heroin without using morphine. 😳🤪
