| 摘 要： | 针对双氧水氧化环己烯制得的有机相,经过环己烯回收和1,2一环氧环己烷精制2次常压精馏,获得了纯度达99.68%的1,2-环氧环己烷.通过内标法定量测定馏出液中环己烯与1,2-环氧环己烷的含量,分别考察了回流比与采出率对环己烯回收和1,2-环氧环己烷纯度的影响,确定了精馏分离的较佳工艺条件:回流比为15,环己烯的采出率为原料液的51%,环氧环己烷的采出率为26%. |

| Abstract: | 99.68%(by mass) 1,2-epoxy cyclohexane was obtained from the oil phase of oxidation of cyclohexene with hydrogen peroxide by two steps of batch distillation at normal pressure,including the cyclohexene recovery and purification of 1,2-epoxy cyclohexane.The contents of cyclohexene and 1,2-epoxy cyclohexane in distillates were determined by the internal standard method of GC.The effects of reflux ratio and recovery rate on the cyclohexene recovery and purification of 1,2-epoxy cyclohexane were investigated and... |
| Keywords: | 1 2-epoxy cyclohexane cyclohexene batch distillation separation |
