A process for esterifying organic carboxylic acids which comprises reacting an organic carboxylic acid with a carbonic acid ester of the formula: ##EQU1## wherein R is an organic group and X and Y are each a negative group in the presence of a basic substance to make esterified the carboxyl group in the organic carboxylic acid. The process is advantageous in affording the objective carboxylic ester in a good yield within a short time by a simple operation under a mild reaction condition.
一种酯化有机羧酸的方法,包括将有机羧酸与碳ic酸酯反应如下公式:其中R是有机基团,X和Y分别是负离子基团,在碱性物质存在下使有机羧酸中的羧基酯化。该工艺的优点在于,在温和的反应条件下,通过简单的操作,可以在短时间内以较高的收率获得所需的羧酸酯。
