摘要:
制备了氯甲基化聚苯乙烯-二乙烯苯接枝磷钨杂多酸季铵盐催化剂,用红外光谱和电感耦合等离子体原子发射光谱对催化剂进行了表征.无溶剂下以H2O2(w(H2O2)=34.5%)和3-环己烯甲酸-3’-环己烯甲酯(简称A)为原料,催化合成3,4-环氧基环己基甲酸-3’,4’-环氧基环己基甲酯(简称AOO),探讨了催化剂用量、n(A):n(H2O2)、反应时间、反应温度等因素对反应的影响.获得了适宜的合成条件为(以60mmol A计):反应温度65 ℃,反应时间100 min,催化剂用量5.0 g,n(A):n(H2
Abstract:
Chloromethylated polystyrene divinylbenzene grafted quaternary ammonium salt of phosphor—tungsticheteropoly acid had been prepared as acatalyst.The catalyst had been characterized by IR spectrum and inductively coupled plasma atomic emission spectrometry. 3,4-Epoxycyclohexylmethyl一3’,4’一EpoxycyclohexaneCarboxylate(A00)had been synthesized by epoxidation of 3一Cyelohexenylmethyl 3 7-Cyclohexeneearboxylate(A)with hydrogen peroxide(W(H202)=34.5%)as oxidant under organic solvent—free condition.The maininfluence factors in the reaction,such as mole ration of A to H2 02,reaction time,temperature,amounts ofcatalyst and SO on,had been studied.The appropriate reaction condition are as fallows(based on 60 mmolA):reaction temperature 65℃,reaction time 100 minutes,catalyst 5.0 g,n(A):n(H202)=1:3.Underthe condition.average conversion of A is more than 99%and average yield of AOO is 78.9%.The averagerecovery of catalyst is over 93%.
