| 考察了几种Ｆｅ－大环配合物与Ｐｄ（ＯＡｃ）２组成的双组分催化体系，在乙腈酸性水溶液中环己烯经合成环己酮的催化活性，实验结果表明，其中以酞菁失（ＦｅＰｃ）与Ｐｄ（ＯＡｃ）２组成的催化体系活性最高，而ＦｅＴＰＰＣｌ与Ｐｄ（ＯＡｃ）２催化体系，虽然催化活性较高，但催化剂的稳定性较低，各种因素对Ｐｄ（ＯＡｃ）２／ＦｅＰｃ催化活催化影响的研究结果指出，在无水和酸存在的非水溶液中，Ｐｄ（ＯＡｃ）２／ＦｅＰｃ对 |
| 英文摘要: |
| The catalytic activities of several catalysts consisted of Pd(OAc) 2 with different Fe Macrocyclic compounds for the oxidation of cyclohexene to cyclohexanone in an acidic aqueous solution of MeCN were investigated. The experimental results indicated that, the catalytic activity of Pd(OAc) 2 with FePc was the highest among the catalysts examined. Although the catalytic activity of FeTPPCl/Pd(OAc) 2 catalyst system is also high, but the stability of the catalyst is lower under the same reaction conditions. The investigation of the influence of reaction conditions on the catalytic activity of Pd(OAc) 2/FePc in the oxidation of cyclohexene showed that, the Pd(OAc) 2/FePc did not give any catalytic activity in the absence of water and acid in the MeCN solution medium. It is suggested that the mechanism of oxidation of cyclohexene to cyclohexanone catalyzed by Pd(OAc) 2/FePc in an acidic aqueous solution of MeCN was similar to that of Wacker catalyst system. FePc plays the role of a catalyst which regenerates the active catalyst in the reaction process. |
