摘要
用化学掺杂的方法,将钼钒磷杂多酸(HmPMo12-nVnO40HPA)固载于漆酚聚合物(UR-HPA)中。通过红外光谱、热重等测试手段对所制得的UR-HPA进行了表征。结果显示HPA和UR间进行了化学键合。同时以缩合反应为催化模型,考察了催化剂在缩酮反应中的催化活性,在UR-HPA催化剂存在下,环己酮乙二醇缩酮(CHGK)的得率为88.4%,催化剂重复使用15次后,CHGK得率仍有85.2%。
Urushiol resin catalyst doped chemically with molybdovanadophosphoric acid （UR-HPA） was prepared by polymerization method. The prepared resin was characterized by FT-IR and thermogravimetiy （TG-DTG）. The results showed that chemieal bond was formed between molybdovanadophosphoric acid and urushiol resin. The catalytic activity of the resin was investigated by synthesis of ketals. In the system of eyclohexanone-ethlene glycol ketal （CHGK） catalyzed by UR-HPA, CHGK yield is 88.4 %. The catalyst can be reused for fifteen times, keeping CHGK yield at 85.2 %.
