How to make ethyl p-aminobenzoate by reflux?
Pass dry hydrogen chloride through the alcohol until saturated; the increase in weight is about 20 g; remove the gas inlet tube, introduce 12 g (0.088 mol) of p-aminobenzoic acid and heat the mixture under reflux for 2 hours. Upon cooling, the reaction mixture sets to a solid mass of the hydrochloride of ethyl p-aminobenzoate.
Can a benzocaine be extracted from sodium bisulfate?
Under these conditions, much of the nonionic benzocaine formed in the experiment should remain dis- solved, and some ionic sodium bisulfate and unreacted sodium p–aminobenzoate may precipitate. Extraction of ths mixture with ether permits the separation of the benzocaine from the ionic compounds.
How to make ethyl p-aminobenzoate from benzocaine?
Step 1: Preparation of p-aminobenzoic acid. Place 15 g (0.09 mol) of p-nitrobenzoic acid in a 1-litre round-bottomed flask fitted with a reflux condenser. Introduce 35 g (0.295 mol) of powdered tin and 75 ml of concentrated hydrochloric acid. Heat the mixture gently until the reaction commences, and remove the flame.
