Abstract

Abstract: A copper -containing molecular sieve Cu-HMS was synthesized using the neutral templating pathway at room temperature．Then the product was used as heterogeneous catalyst for the oxidation of cumene under mild conditions．The results show that Cu-HMS-3with copper nitrate as copper source has excellent catalytic activityhigh cumene conversion and cumene hydroperoxide selectivitythat is39．6％ and98．5％．The catalyst can be recycled．Furthermorethe oxidations of toluene and ethylbenzene were investigated with Cu-HMS-3as catalyst．It is found that there is no oxidation reaction observed for toluene．The activities of the three aromatic hydrocarbons follow the order of toluene≪ethylbenzene＜cumene．

Key words: Cu-HMS molecular sieve, aromatic hydrocarbon, cumene hydroperoxide, catalytic oxidation
