【摘要】 研究了以硅铝酸盐（Al₂O₃/SiO₂）为催化剂,环己醇脱水制备环己烯的反应。考察了催化剂用量、反应温度和时间对脱水反应的影响,确定了适宜的工艺条件:催化剂用量为环己醇质量的 5％,反应时间4 h,反应温度155℃。在此条件下,环己烯收率达95％以上,催化剂可重复使用。更多还原

【Abstract】 The reaction of cyclohexene from cyclohexanol by dehydration using aluminosilicate as catalyst was stud-ied . The influences of amount of catalyst, reation time, and reation temperature on the dehydrating reaction were in-vestigated . The optimum conditions of preparation were determined as follows: amount of catalyst was 5 % ( based on mass of cyclohexanol) , reaction time 4 h, and reaction temperature 155 ℃ . The yield of cyclohexene was up to 95 % under the above conditions. The catalyst could be utilized repeatedly.更多还原
