The reaction of carboxylic acids with (chloromethyl)oxirane (epichlorohydrin, ECH) is used in the synthesis of glycidyl carboxylates, which have different applicathion, for example in the synthesis of epoxy resins. The presence of aromatic cycle in the structure of benzoic acid is its advantage over other carboxylic acids, because it’s ensures the thermal stability of the products. Quaternary ammonium salts are effective catalysts the acidolysis of ECH. An important feature of the reaction was found in previous studies. It has been determined that real reaction catalyst is intermediate compound – carboxylate quaternary ammonium. Based on the above the studying of reaction’s mechanism and the behavior of the quaternary ammonium salts are the actual problem.
