摘要: 合成了聚γ-(顿氨酸基)丙基硅氧烷钯催化剂当N/Pd摩尔比为3.4时,这种催化剂在常温常压下对丙烯腈的加氢活性高达3057·6mL H2/min·mmolPd;对环戊二烯的氢化反应是分两步进行的。溶剂对催化剂的活性有明显影响。

Abstract: The poly-r-(lysine) propylsiloxane supported palladium catalysts were synthesized andcharacterized. The catalysts showed a high activity for acrylonitrile hydrogenation whenthe molar ratio of N/Pd was 3.4. The hydrogenation of cyclopentadiene appeared to be atwo-stage process. The solvents have an obvious influence on the hydrogenation activity ofthe catalyst.

Key words: polymeric palladium catalyst, L-lysine, polysiloxane, hydrogenation, acrylonitrile, cyclopentadiene
