摘要
对以磷钨酸为催化剂环己醇脱水制备环己烯的反应进行了研究。其最佳反应条件为 :催化剂用量为环己醇质量的1% ,油浴温度为 190～ 2 0 0℃ ,反应时间 1h,转化率可达 89.1%以上 ,产品纯度为 97.4% 。
The research on the dehydration of cyclohexanol to prepare cyclohexene using phosphotungstic acid as catalyst is made.The most suitable conditions for the reaction are as follows:the mass ratio of catalyst to cyclohexanol is 1%, the reaction is carried out at a temperature range (oil bath) of 190~200℃ and the reaction time is 1 hour. The conversion rate can reach more than 89.1%, the product purity is 97.4% and the catalyst can be reused.
