摘　　要：以活性炭负载磷钨酸作催化剂,对环己醇脱水制备环己烯的反应进行研究。考察了催化剂用量,反应时间,反应温度等因素对产率的影响。得出了最佳的反应条件:催化剂用量为环己醇质量的2.7%,反应时间30 min,产率可达93.50%。Cyclohexene was synthesised by dehydration of cyclohexanol using phosphotungstic acid supported on active carbon as catalyst. The effect of various reaction parameters such as catalyst amount, reaction temperature and reaction time investigated was investigated. The optimum reaction conditions were ： the amount of catalyst, 2.7 % of the amount of cyclohexanol ; reaction temperature, 80 - 90 ℃ ; reaction time, 30 min. The yield of cyclohexene reached 93.50 % under the optimum conditions.
