Regularities of acidolysis of chloromethyloxirane upon catalysis by quaternary ammonium salts.

Abstract

The kinetic regularities of acidolysis of chloromethyloxirane depending on the ratio of components in the system "chloromethyloxiran - benzoic / acetic acid - tetraethylammonium bromide / benzoate" were studied. The range of concentrations of carboxylic acids in which the constant order of reaction is observed is established. The zero order of the reaction for the reagent is performed in the range of concentrations for acetic acid 0.05 ÷ 0.50 mol / l, benzoic acid 0.10 ÷ 0.50 mol / l. The range of zero-order carboxylic acids does not depend on the temperature and nature of the reagent. Tetraethylammonium benzoate is an effective catalyst for the acidolysis of chloromethyloxirane, the catalytic activity of which is comparable to tetraethylammonium bromide. This confirms the hypothesis of the formation during the reaction of tetraalkylammonium carboxylates as true catalysts of the process.
