摘　　要：合成了不同Ｎ／Ｐｄ摩尔比的聚γ－（甘－丙二肽基）丙基硅氧烷钯催化剂，用元素分析、红外差谱、ＸＰＳ表征了它们的结构，讨论了催化剂对不同底物的加氢活性以及Ｎ／Ｐｄ摩尔比、溶剂。This paper describes the synthesis of poly γ (L glycylalanine) propylsiloxane palladium catalysts with different N/Pd molar ratios and their catalytic activity.XPS data of the title catalyst indicated that the active center may be complex compound composed of the _COOH and _NH 2 of amino acid ligand and PdCl 2.The hydrogenation activity of the title catalysts is very high for acrylonitrile,propenol and acrylic acid,but inactive for α methyl acrylic acid and 1 decene.The influence of solvents,N/Pd molar tatio,and reaction temperature on catalytic hydrogenation of acrylonitrile was studied respectively.
