The invention relates to a process for the manufacture of a 1,2-epoxide by catalytic oxidation of a terminal olefin with hydrogen peroxide wherein the catalytic oxidation is performed in a biphasic system comprising an organic phase and an aqueous reaction medium, wherein a water-soluble manganese complex is used as oxidation catalyst, wherein a terminal olefin is used with a solubility at 20°C of at least 0,01 to 100 g in 1 liter water, and wherein the molar ratio of terminal olefin to hydrogen peroxide is in the range of from 1:0.1 to 1:2.
本发明涉及一种通过使用过氧化氢对末端烯烃进行催化氧化制备1,2-环氧化物的工艺,其中催化氧化是在包含有机相和水相反应介质的两相系统中进行的,其中水溶性锰配合物被用作氧化催化剂,其中末端烯烃的溶解度在20°C时至少为0.01至100克/升水,末端烯烃与过氧化氢的摩尔比在1:0.1至1:2的范围内。
