摘要：
General acid-catalyzed reaction can be enhanced by the addition of base. Self-catalyzed esterification of benzoic acid and octan-1-ol was enhanced by the addition of certain base such as imidazole. The rate of the esterification was accelerated as the concentration of imidazole increased. Trans-esterification of 4-nitrophenyl acetate was promoted in chloroform by the mixture of benzoic acid and imidazole, but not by benzoic acid or imidazole alone.
