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。 Reported the synthesis of poly (γ- (ethylenediamino) propylsiloxane palladium and zinc bimetallic catalysts with different N / Pd molar ratios and their hydrogenation activities on different substrates. The effects of different solvents and temperature On the catalytic activity. The results show that under the same conditions, the activity of bimetallic catalyst is larger than that of monometallic palladium catalyst, more than the mixture of monometallic palladium and monometallic zinc catalyst, and the hydrogenation activity of bimetallic catalyst increases with the increase of N / Pd molar ratio Increase.
