摘要
以对甲苯磺酸为催化剂，对苯二酚为阻聚剂，采用酸醇直接酯化新方法合成了二（甲基丙烯酸）乙二醇酯，二（甲基丙烯酸）二甘醇酯，二（甲基丙烯酸）聚乙二醇－２００酯。所得产物颜色浅，纯度及收率高。并对产物进行了ＧＣ、ＩＲ、１ＨＮＭＲ。
Glycol dimethacrylate,diethylene glycol dimethacrylate and polyglycol (200) dimethacrylate were synthesized by direct esterification when pmethylbenzene sulfonic acid was used as catalyst and pdihydroxybenzene as inhibitor.The products are light color,high purity and high yield.They were analysed by GC,IR,1HNMR and MS.
