The present invention provides a safe, convenient and efficient method for producing carboxylic acid by a reaction of alicyclic alcohol with an aqueous hydrogen peroxide to thereby obtain carboxylic acid in high yield from alicyclic alcohol or alicyclic ketone under mild reaction conditions, wherein the reaction operation is simple and easy, a step for removing solvent after completion of the reaction is not necessary and influence and toxicity upon the environment and human body are markedly small. In order to provide it, an oily alicyclic alcohol is allowed to react with an aqueous hydrogen peroxide in the presence of a catalyst containing a metal compound belonging to Group 6 of the Periodic Table in a heterogeneous solution system.
本发明提供了一种安全、方便、高效的生产羧酸的方法,该方法通过脂环醇与过氧化氢水溶液反应,从而在温和的反应条件下,从脂环醇或脂环酮中高产率地获得羧酸,反应操作简单易行,反应完成后无需去除溶剂的步骤,对环境和人体的影响和毒性明显较小。为了实现这一目标,需要在一个异相溶液体系中,在含有元素周期表第 6 族金属化合物的催化剂存在下,使油性脂环醇与过氧化氢水溶液发生反应。
