烯烃环氧化在现代化学中具有重要的学术和工业价值,但采用绿色氧化剂过氧化氢仍面临传质的挑战。采用过氧缩合法制备了一种新型钨基催化剂,用于过氧化氢与环己烯环氧化研究,环己烯的转化率为51.2%,环氧环己烷的选择性为69.2%。结果显示该催化剂催化活性高,环氧环己烷的选择性好,反应条件温和,工艺无溶剂且绿色环保。 Epoxidation of olefins has important academic and industrial value in modern chemistry, but the use of the green oxidizer hydrogen peroxide still poses the challenge of mass transfer. A new type of tungsten-based catalyst was prepared by the method of peroxide condensation. It was used in the epoxidation of hydrogen peroxide and cyclohexene. The conversion of cyclohexene was 51.2% and the selectivity to cyclohexene oxide was 69.2%. The results show that the catalyst has high catalytic activity, good selectivity for cyclohexene oxide, mild reaction conditions, no solvent and environmental protection.
