| 摘 要： | 本文报道了不同N/Pd摩尔比的聚γ-(甘-色二肽基)丙基硅氧烷钯催化剂的合成及对烯烃和硝基苯的加氢活性.催化剂的结构表征说明,其活性中心的组成可能是氨基酸配体的羧基与PdCl_2的络合.这种催化剂对丙烯腈和苯乙烯有较高的加氢活性,而对硝基苯的氢化没有催化活性.并研究了溶剂和温度对加氢活性的影响.

| Abstract: | This paper is concerned with synthesis of poly-γ-(L-glycyltrytophane) propylsiloxane palladium catalysts in different N/Pd ratioes and study on its hydrogenation activity for olefins and nitrobenzene. The structural characterization of the title catalysts indicates that the activity center may be complex compound composed of the -COOH of amino acid ligand and PdCl3 The hydrogenation activity of the title catalysts is very high for acrylonitrile and styrene, but inactive for nitrobenzene. Besides, the hydrogenation activity was influenced by solvent and reaction temperature. |
