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甲苯 乙苯
A copper-containing molecular sieve Cu-HMS was synthesized using the neutral t emplating pathway at room temperature. Then the product was used as heterogeneou s catalyst for the oxidation of cumene under mild conditions. The results show t hat Cu-HMS-3 with copper nitrate as copper source has excellent catalytic acti vity, high cumene conversion and cumene hydroperoxide selectivity, that is, 39.6 % and 98.5%. The catalyst can be recycled. Furthermore, the oxidations o f toluene and ethylbenzene were investigated with Cu-HMS-3 as catalyst. It is found that there is no oxidation reaction observed for toluene. The activities o f the three aromatic hydrocarbons follow the order of tolueneethylbenzene<cume ne.
