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%.
