摘要
以单质碘为催化剂,通过乙酸酐、环己醇及乙酸、环己醇为原料合成乙酸环己酯,对碘的催化活性进行了研究。研究表明:在优化条件下收率可分别达98.9%、58.1%。将实验结果与文献数据综合分析,得出了碘作为催化剂在酸醇直接酯化反应中的催化活性不高。
The catalytic activity of iodine in the esterification reaction was studied by synthesis cyclohexyl acetate from acetic anhydride, cyclohexano and acetic acid, cyclohexano. Using iodine catalysis, the yield reached 98.9% in acetic anhydride and cyclohexano reation, while the yield was only 58.1% in acetic acid and cyclohexano reation. According to the results and data reported, it was given that the catalysis activity of iodine in acid and alcohol esterfication is not high.
