Epoxides are manufactured by reacting olefines, such as cyclohexene, isoamylene, alpha-pinene, allyl alcohol, 2,5-dihydrofuran and styrene, with hydrogen peroxide, in a homogeneous liquid reaction mixture containing less than 10% by weight of water, in the presence of a compound of a metal of group 6a, such as selenium dioxide or selenous acid, and of an organic nitrogen-containing base having a pKa of not more than 8, such as pyridine, chloropyridine, collidine, quinoline, isoquinoline or a lutidine.
环氧化物是通过将烯烃(如环己烯、异戊烯、α-蒎烯、烯丙醇、2,5-二氢呋喃和苯乙烯)与过氧化氢反应而制得的,在均相液体反应混合物中,水含量不超过总重量的10%,同时加入一种6a族金属化合物(如二氧化硒或亚硒酸)和一种有pKa不超过8的含氮有机碱(如吡啶、氯吡啶、哥林啶、喹啉、异喹啉或戊二酸)。
