Salalen-Co配合物催化环己烯环氧化研究

Study on Epoxidation of Cyclohexene Catalyzed by Salalen-Co Complex

本文以Salalen-Co配合物为催化剂,30%H_2O_2为氧源,对不同溶剂/NaHCO_3混合溶液中环己烯环氧化工艺进行了优化试验研究。探讨了对反应温度、反应时间、H_2O_2与环己烯物质的量比例及溶液pH值对环己烯氧化的影响.在最佳条件下,环氧环己烷的最佳收率和选择性分别为92%和78%。

The process optimization of epoxidation of eyelohexene with 30% hydrogen peroxide in the different solvent/ sodium bicarbonate solution were studied by using Salalen - Co complex as the catalyst in this paper. The effects of reaction temperature, reaction time, molar ratio of H2 O2 to eyelohexene and pH value on the oxidation of eyelohexene were discussed. The opfimunl yield and selectivity of eyelohexane were 92% and 78% respectively.
