    摘要: Process for the epoxidation of olefins with oxygen or air, and a redox system, in the presence of a titanium silicalite, whereby the redox system is selected from

    i) quinone/hydroquinone derivatives substituted with a -(CH 2 ) n -N + (R 2 ) 3 , -(CH 2 ) n -CO - N + (R 3 ) 4 or -(CH 2 ) n -CO 2 - M + group, or
    ii) acetophenone/1-phenyl ethanol derivatives substituted with a group as indicated for the quinone/hydroquinone system, or with a group -(CH 2 ) n -SO 3 - N + (R 6 ) 4 .
