聚γ-（乙二胺基）丙基硅氧烷钯锌双金属催化剂的合成及加氢活性 THE SYNTHESIS AND HYDROGENATION ACTIVITY OF POLY-γ-（AMINOETHYLAM INO） PROPYLSI LOXANE PALLADIUM-ZINC BIMETALLIC CATALYSTS 刘基万 Liu Jiwan 1 first-author 游江 You Jiang 1 姚朝云 Yao Chaoyun 1 武汉大学化学系 武汉大学化学系 Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University 报导了4种不同N/Pd摩尔比的聚γ-（乙二胺基）丙基硅氧烷钯、锌双金属催化剂的合成及其对不同底物的加氢活性,研究了不同溶剂和温度对催化活性的影响。结果表明,在同样条件下,双金属催化剂的活性大于单金属钯催化剂,更大于单金属钯和单金属锌催化剂混合物,而且双金属催化剂的加氢活性随着N/Pd摩尔比的的增加而增大。 This paper is concerned with the synthesis of title complexes and hydrogenation activity for olefins and nitrobenzene etc. The influence fo various solvents and reaction temperature on catalytic activity is also studied. The data indicate that the catalytic activity of the title complexes for hydrogenation of acrylonitrile is higher than that of the palladium nitrogen complexes and the mixture of the later and the bound zinc complexes. Besides,the hydrogenation activity increases with the increase of N/Pd radio. 聚硅氧烷 双金属化合物 催化剂 加氢活性 polysiloxane bimetallic complex catalyst hydrogenation activity 国家自然科学基金(61672102) 1990-04-01 2021-04-01 4
