| 摘 要： | 以沉积-沉淀法制备了Au-Co/SBA-15催化剂,在没有任何有机溶剂或助剂的条件下,研究了以空气为氧化剂的环己烷选择性氧化。当Au-Co/SBA-15催化剂中金的质量百分含量为1.0%,催化反应在423 K 3.0 MPa下进行120 m in时,催化效果最好,此时环己烷的转化率为22.7%,环己酮和环己醇的总选择性为95.2%,酮醇比为2.9,且催化剂重复使用五次后活性基本不变。

| Abstract: | Without any organic solvent or activator,the selective oxidation of cyclohexane with air to afford cyclohexanol and cyclohexanone was investigated over Au-Co/SBA-15 catalysts prepared by deposition-precipitation method.The best result was obtained over Au-Co/SBA-15(Au 1.0%) catalyst with conversion of 22.7% and selectivity of 95.2%,and the ratio of cyclohexanone to cyclohexanol was 2.9,when the reaction was carried out at 423 K for 120 min under 3.0 MPa,and catalytic activity did not change after five runs. |
