  PROBLEM To provide an environmentally-friendly method for producing industrially an ester compound. SOLUTION The present invention is a method for producing an ester compound which comprises subjecting a carboxylic acid and an alcohol to dehydration-condensation reaction using an involatile acid catalyst and then removing the residual acid catalyst by bringing a weak basic substance into contact with the residual acid catalyst.

  问题提供一种生产工业酯化合物的环保方法。 解决方案是一种生产酯化合物的方法，包括将羧酸和醇经过脱水缩合反应，使用一种不挥发的酸催化剂，然后通过将弱碱性物质与残留的酸催化剂接触来去除残留的酸催化剂。
