文章研究了环己酮液相催化合成环己烯基环己酮过程中,不同种类酸催化剂的作用规律和反应机理. 结果表明,强质子酸催化反应的速率较快,催化反应活性亦高,但后处理需经中和、洗涤、干燥等繁琐工序,存在污染环境和腐蚀设备等弊端;详细考察硫酸盐、氯化物盐类等Lewis酸催化剂对反应的催化作用,并比较了催化剂用量、反应时间的影响,发现铁盐的催化性能较好,缩合单程产率高. In this paper, the action law and reaction mechanism of different kinds of acid catalysts in the cyclohexanone cyclohexanone catalyzed synthesis of cyclohexenylcyclohexanone were studied.The results showed that the catalytic reaction rate of strong proton acid was high and the catalytic activity was high, However, the post-treatment needs to be neutralized, washed, dried and other tedious processes. There are disadvantages such as environmental pollution and corrosion equipment. The catalytic effect of Lewis acid catalysts such as sulfate and chloride salts on the reaction is examined in detail. The amount of catalyst, The influence of time, found that the catalytic performance of iron salts is better, high yield one-way condensation.
