Methyl esterification of carboxylic acids with dimethyl carbonate promoted by K2CO3/tetrabutylammonium chloride

Abstract

A facile and green process in which K2CO3 in combination with the phase transfer catalyst tetrabutylammonium chloride was explored to promote the esterification of carboxylic acids with dimethyl carbonate has been developed. High yield and purity were observed for most of the investigated methyl esters. © 2013 Copyright Khiem D.N. Chau, Fritz Duus and Thach N. Le.
