academia is fake you can only trust your fists
Are you suggesting we start punching professors?
idk about you but I know a couple of profs who could use a swift punch in the teeth

That’s right, pour 6 ounces of cocaine and 20 vitamin tablets in your coffee and you’ll never have to sleep again.
Preparation of an acid chloride from the corresponding carboxylic acid and some thionyl chloride.
SOCl2 + RCO2H → RC(O)Cl + SO2 + HCl
The recipe is easy. Get a flask, a reflux condenser and a dropping funnel, weight out the acid into the flask, a few drops of N,N-dimethylformamide to catalyze the reaction and add slowly a slight excess, usually 1,2 molar equivalents of thionyl chloride. Heat and stir until no more gas evolves and distill what’s left in the flask to obtain a pure product. Yield: +99%.
However care should be taken, since highly toxic hydrogen chloride and sulfur dioxide is evolved from the reaction (as seen of the gif). The chlorinating agent what’s used, thionyl chloride and the product is toxic and will react violently with water to produce toxic gases.
The N,N-dimethylformamide catalyzes the reaction according to the following scheme:
Funfact: purification of thionyl chloride is performed by distilling it from linseed oil.
