| 摘 要： | 以环境友好的离子液体[BMIm]NO3为催化剂,采用环己醇脱水反应清洁合成环己烯。考察了反应温度、反应时间、催化剂用量对产品收率的影响。结果表明,在[BMIm]NO3与环己醇的摩尔比为1∶33,于180℃、反应2 h的条件下,产品收率可以达到93%,离子液体催化剂重复使用4次时,环己烯的收率仍可达到88%。

| Abstract: | Cyclohexene was synthesized from cyclohexanol catalyzed by ionic liquid [BMIm]NO 3.The effects on the reaction,such as the reaction temperature,the reaction time,and the molar ratio of [BMIm]NO 3 to cyclohexanol were investigated.When the reaction was carried out at 180 ℃ for 2 h,and n（[BMIm]NO 3） ∶ n（cyclohexanol） =1 ∶ 33,the isolated yield of the product reached 93%.Moreover,the ionic liquid could be reused simply after vacuum distillation.Yield of cyclohexene was 88% when [BMIm]NO 3 was reused 4 times. |
