摘要: There is disclosed a process for efficiently producing a carboxylic acid ester and formamide by reacting a carboxylic acid amide with a formic acid ester or with an alcohol and carbon monoxide in the presence of a strongly basic anion-exchange resin. By the use of the strongly basic anion-exchange resin as the catalyst, the process of the present invention enables the efficient production of the carboxylic acid ester as well as formamide from the Carboxylic acid amide and Formic acid ester, etc. with a high selectivity under mild reaction conditions and facilitates the separation of the catalyst from the reaction product, thereby greatly enhancing the industrial significance of itself.
