| 摘 要： | 以甲基丙烯酸甲酯和二甲氨基乙醇为原料,用二苯基二氯化锡作催化剂,用吩噻嗪作阻聚剂,通过酯交换反应制备了甲基丙烯酸二甲氨基乙酯(DMAEMA)。通过正交实验确定的较佳反应条件为:以w(二苯基二氯化锡)=1.0%,叫(吩噻嗪)=0.8%,n(甲基丙烯酸甲酯)∶n(二甲胺基乙醇)=3∶1;在此条件下,产率可达91.5%,催化剂和甲基丙烯酸甲酯可重复使用。

| Abstract: | The preparation of dimethylaminoethyl methacrylate(DMAEMA)by ester exchange reac- tion of methylmethaclylate with dimethyl-aminoethanol catalyzed by diphenyltin dichloride in the pres- ence of phenothiazine was described.The optimum reaction conditions were obtained as follows,n (methacrylate):n(dimethyl-aminoethano)=3:1,the amount of catalyst 1.0% and the amount of inhibitor 0.8%(both based on the total mass of reaction mixture).Under these conditions,the yield of N,N-dimethylaminoethyl methacrylate was above 91.5%.Unreacted methacrylate and the catalyst can be used repeatedly. |
