新型高分子相转移催化剂——多铵型催化剂的合成及其催化性能研究

HIGH POLYMER PHASE-TRANSFER CATALYSTS - Syntheses of Polyammounium Catalysts Study of Their Catalitic Activities.

近来有关高聚物三相催化剂的报道越来越多。作者合成了五个大孔型聚(苯乙烯-二乙烯苯)支载多铵的催化剂,并在醚合成、卤素交换反应中试验其催化性能,IR光谱证明了此类催化剂的结构。 1.催化剂的制备 (1)

This paper describes syntheses of five macroreticular poly(styren-divinylbenzene)-supported phase-tranfer catalysts. This kind of catalysts is used in the formation of ether and ester, in halide exchange. The results of the study indicate that the catalytic activities are good, and repetition is good.
