以氯甲基化聚苯乙烯为原料，先后接枝聚乙二醇及吡啶，合成了双中心固载相转移催化剂──交联聚苯乙烯固载聚乙二醇４００及吡啶weng盐，并对氯甲基化聚苯乙烯树脂、聚苯乙烯固载聚乙二醇树脂、聚苯乙烯固载吡啶weng盐树脂及双中心树脂进行了红外光谱测试和分析，通过醋酸钾与溴节的反应，对各催化剂进行了活性评价，发现固载双中心相转移催化剂的活性明显高于各单中心固载相转移催化剂。 Using chloromethylated polystyrene as raw material, polyethylene glycol and pyridine were grafted successively to synthesize a dual-site immobilized phase-transfer catalyst-cross-linked polystyrene immobilized polyethylene glycol 400 and pyridine weng salt FTIR spectra and analysis were carried out on chloromethylated polystyrene resin, polystyrene immobilized polyethylene glycol resin, polystyrene supported pyridine weng resin and bidentate resin. The reaction of potassium acetate with bromine , The activity of each catalyst was evaluated and it was found that the activity of the immobilized bi-center phase transfer catalyst was significantly higher than that of the single center-supported phase transfer catalyst.
