摘　　要：本文报导7四种不同-COOH/Pd摩尔比的聚γ—(丝氨酸基)丙基硅氧烷钯催化剂的合成及其XPS结构表征。加氢实验结果表明,这种催化剂对所用底物有高的催化活性,当-COOH/Pd比、内3.76:1时,对苯乙烯的起始加氢速度达2558.9mLH_2/min.mmolPd,并讨论了不同溶剂和温度对催化剂活性的影响。This paper concerns with syntheses of poly-γ-(L-serine)propylsiloxane palladium complex catalysts in different -COOH / Pd ratio and study on its XPS analysis. The data indicate that the hydrogenation activity of the title catalysts is very high.Initial hydrogen absorption rate for styrene hydrogenation is 2558.9mLH2/min.mmol Pd when the -COOH /Pd mol ratio is 3.76 :1. Besides, the hydrogenation activity is found to be influenced by the solvent and the temperature of the experiments.
