摘要: 采用中性模板法于室温下合成了含铜的分子筛 Cu-HMS‚并以该分子筛为多相催化剂‚对温和条件下异丙苯的氧化进行了研究.结果表明‚以硝酸铜为铜源的 Cu-HMS-3催化剂具有很高的催化活性‚异丙苯转化率和过氧化氢异丙苯选择性都很高‚分别达39.6%和98.5%.催化剂可以回收使用.另外‚以 Cu-HMS-3为催化剂对甲苯和乙苯的氧化进行了研究‚发现在本实验条件下‚甲苯未发生反应‚3种芳烃的活性顺序为苯≪乙苯<异丙苯.

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 activity‚high cumene conversion and cumene hydroperoxide selectivity‚that is‚39.6% and98.5%.The catalyst can be recycled.Furthermore‚the 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
