Abstract:

From the oil phase reaction liquor of H₂O₂ oxidation of cyclohexene，epoxycyclohexane was separated and purified by atmospheric distillation，and the optimum conditions were determined. Under the optimum conditions the purity of epoxycyclohexane obtained was 99.59% and the single pass yield of product was 85.87 %. Epoxycyclohexane in the high boiling point bottom residue was recovered by vacuum distillation，and the total yield of epoxycyclohexane could be over 90%.

摘要：

针对无溶剂法双氧水氧化环己烯合成环氧环己烷的油相反应液，采用常压精馏的方法对其进行了分离纯化，并得到了常压精馏操作的较佳工艺条件。在此工艺条件下，环氧环己烷的纯度和单程收率分别达到99.59%和85.87%，对常压精馏后的塔釜高沸点残留物进行减压精馏回收后，环氧环己烷总收率可以达90%以上，为其工业化生产提供重要的实验依据。
