摘要
This paper describes the synthesis of poly-γ-(L-glycylalanine) propylsiloxane palladium catalysts withdifferent 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 -NH2 of amino acid ligand and PdCl2. The hydrogenation activity of the title catalysts is very high for acrylonitrile,propenol and acrylic acid,but inactive for a-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.
