2-Methylbenzoic acid as a proton-containing nucleophile in the reaction oxirane ring-opening

Abstract

The kinetic regularities of epichlorohydrin acidolysis with 2-methylbenzoiс acid in the presence of catalysts: tetrabutylammonium iodide in the temperature range 40 ÷ 70◦C were studied. The first order of the reaction on the catalyst and the zero order of the reaction on the acid were determined. The kinetic law of reaction is established. The rate constants of the noncatalytic and catalytic stages of reaction were calculated. The effectiveness of tetrabutylammonium iodide as a reaction catalyst has been proven. The activation parameters of the reaction corresponding to the reactions of bimolecular nucleophilic substitution were determined.
