杨梅形高分子载体的链结构对钯加氢催化剂活性的影响

制备了四种杨梅形高分子载钯催化剂,考察了它们对苯乙烯的催化加氢活性。结果表明、具有不同配位功能基的催化剂,其催化活性有较大差异,其中对金属离子吸附能力弱的分散钯催化剂表现出较高的催化活性。接枝链上嵌入丙烯酸甲酯单元抑制了催化剂的加氢活性。反应体系的酸度对催化剂的活性的影响比较复杂,有等进一步探讨。

CATALYTIC HYDROGENATION ACTIVITY OF PALLADIUM (O) DISPERSED IN "ARBUTUS" RESIN

Several "Arbutus" resins dispersed Palladium catalysts were prepared and used for the hydrogenation of styrene. It has been found that the activity of the catalyst was affected by functional group and the fundamental chain structure of polymer. The acidity of the reaction system also affected the hydrogenation activity of the catalyst.
