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.
In this paper, the synthesis of poly-γ- (Gan-Dipeptidyl) propylsiloxane with different molar ratio of N / Pd and the hydrogenation activity of olefins and nitrobenzene have been reported. The structural characterization of the catalyst shows that its activity The composition of the center may be the complexation of the carboxyl group of the amino acid ligand with PdCl 2 .This catalyst has higher hydrogenation activity for acrylonitrile and styrene and no catalytic activity for the hydrogenation of p-nitrobenzene.The effects of solvent and temperature Effect on hydrogenation activity.
