摘要 Reactive distillation could be utilized to produce cyclohexanol through the cyclohexene hydration. By means of highly active zeolite catalyst HZSM-5, the kinetic-thermodynamic analysis of this reactive distillation has been carried out to get the characteristics of the reactive distillation. Results from kinetic and thermodynamic analysis indicate that the optimal pressure of this reactive distillation process should be set to higher pressure such as 0.3 or 0.4 MPa. To avoid the recovery of cyclohexanol at the top of the column, an unreactive section should be allocated at the upper column. In addition, the inert component benzene is more unfavorable to the reactive distillation process in comparison with the inert cyclohexane. 反应蒸馏能被利用通过 cyclohexene 水和生产 cyclohexanol。借助于高度活跃的沸石催化剂 HZSM-5,这反应蒸馏的运动热力学的分析被执行了得到反应蒸馏的特征。从运动、热力学的分析的结果显示这个反应蒸馏过程的最佳的压力应该被设为象 0.3 或 0.4 MPa 那样的更高的压力。在列的顶避免 cyclohexanol 的恢复, unreactive 节应该在上面的列被分配。另外,惰性的部件苯对与惰性的环己烷比较的反应蒸馏过程更相反。
