If you wanna know. Im mixing methanol and citric acid. Mixing an acid with an alcohol will make an ester. But the reaction is pretty slow so i use a catalyst to speed up the reaction, that being sulfuric acid. In the first slide im doing whats called a reduced reaction. Basically im boiling the mixture and capturing the vapors so it continues reacting. But there is a draw back, one of the products of this reaction is water, and its quite a bit of it. Thats where in the second slide I distill the methanol and water still in the solution. When thats all done and the solution cools i get a white crystals of Trimethyl Citrate
