由氯甲基化的聚苯乙烯—二乙烯苯树脂可制得溴吡啶甲基化聚苯乙烯树脂和二苯基膦吡啶甲基化聚苯乙烯树脂。将苯氰氯化钯和二苯基膦吡啶甲基化聚苯乙烯树脂反应可得负载化的加氢催化剂。考查了其对异丙叉丙酮加氢反应的催化性能。
Bromopyridine methylated polystyrene resin and diphenylphosphinopyridine methylated polystyrene resin can be prepared from chloromethylated polystyrene-divinylbenzene resin. Reaction of palladium cyanide palladium with diphenylphosphinopyridine methylated polystyrene resin gives a supported hydrogenation catalyst. The catalytic performance for the hydrogenation of isopropylidene acetone was investigated.
