摘要：
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 to approximately 200 C 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.
