摘要

Preparation of 1-8C alkane carboxylic acid 1-4C alkylester (I) comprises: preparing a reaction mixture comprising 1-8C alkanecarboxylic acid, acid catalyst, 1-4C-alkanol, water and optionally an inert diluent, where the molar ratio of water to 1-4C alkanol is at least 0.2; and esterification of 1-8C alkane carboxylic acid with 1-4C alkanol in the reaction mixture under the formation of (I) and simultaneously distillating the mixture comprising or consisting of water, 1-4C-alkanol and (I).
