Liquid-phase epoxidation of styrene with O_2 over alkali metal salt impregnated CoAPO-5

Liquid-phase epoxidation of styrene with atmospheric O_2 was conducted over CoAPO-5 molecular sieves.The catalytic performance of CoAPO-5 can be significantly improved by alkali metal salt impregnated on it,and styrene conversion and selectivity to styrene oxide reached 85%and 69%respectively when C...

Summary:Liquid-phase epoxidation of styrene with atmospheric O_2 was conducted over CoAPO-5 molecular sieves.The catalytic performance of CoAPO-5 can be significantly improved by alkali metal salt impregnated on it,and styrene conversion and selectivity to styrene oxide reached 85%and 69%respectively when CsCl was impregnated on it.The catalyst was recyclable and exhibited similar catalytic activity and selectivity even after three catalytic reaction cycles.
