【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。更多还原

【Abstract】 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.更多还原
