I know shaking the toluene with KMnO4 with your hands was for the meme, but just in case it wasn't: toluene can pretty easily penetrate most thin gloves (latex,butyl), neoprene/nitrile are slightly better but toluene will still penetrate after about a minute after contact, so they should be removed/replaced quickly after contact. Not nearly as scary as benzene but you still don't want it in contact with your skin for a long time

@@tarus94 Carbon tetrachloride is a fantastic solvent for many substances, and a fire extinguishing agent. Too bad it's also very carcinogenic, and if you put out fires with it you can accidentally decompose it into phosgene. Today it's used in small amounts in animal testing to reliably induce cancer in the test animals, horrifying stuff. Benzene is also good solvent and paint thinner, but carcinogenic.

When you mix the oxidizer with water and then with the product You want to oxidize, you could use a big seperating funnel instead of erlenmeyer, by that you can shake your reaction mixture more easy and nothing of it gets in contact with your gloves aswell . You only have to ventilate it from time to time while shaking

Suggestion for heating glassware if you're using a torch- place the flask inside a steel can with a couple inches of sand in the bottlm, fill the space around the flask with more sand. This will distribute the heat and prevent glass from cracking.

Sodium benzoate is pretty useful and valuable all by itself. I think that NAPALM is more like aluminum soap that is then mixed with gas. So, technically, your legal on that point. I've heard about something like this before, been a while, but the benzoate is mixed with lime and then heated, in a tin can? You get CaCO3 and benzene. Like your lab set up.

I'm a little confused where all your potential yield was lost? to the air? Maybe the permanganate didn't completely react? Seems odd to me. I also clicked on this video because I have a lottt of styrofoam i've just dissolved into acetone and not sure what to do with lol. I think KZbin knows
@Prussian_Blue5 ай бұрын
Well, the shitty yield is mostly due to the last step when i was decarboxylating the benzoate, that's because the benzoate and hydroxide wasn't very well mixed, it wouldn't be a problem if i've chosen a flask that was apprioporate size, but i didnt have one because ive had glassware shortages back then. also glass is a really bad choice not only due to the molten NaOH leaching into the glass. also because the glass vessel i've chose was too big and the heat was spread out unevenly and it started cracking, if you want to have a better yield, use a coffee grinder or something to mix the benzoate and hydroxide evenly, and you can sprinkle in some calcium oxide for extra spice. also im not sure if you remember this, but ive once done those out of context compilation videos when i was starting out and ive made one on you and i remember you leaving a comment on it when you were still known as nilegreen lol. also the permanganate part should be mostly decent yield, but ive added a little bit less, because ive ran outta it, you can improve the yield, by refluxing longer than i did.

best you can do to get pure benzene is to take benzoic acid in the most pure form you can get and heat it above 370C ish in a reaction vessel wich has a pressure relief valve. this will generate benzene and CO2 wich escapes through the valve. only open the vessel after it cooled to room temp by itself.
