    摘要: Process for the epoxidation of olefins with oxygen and/or air and a redox system, in the presence of titanium silicalite, characterized in that the redox system is selected from: 1) quinone/hydroquinone derivatives having the general formula (Ia) and (Ib) ##STR1## 2) acetophenone/1-phenyl ethanol derivatives having the general formula (IIa) and (IIb) ##STR2##
