摘要/Abstract

摘要： 通过与环己胺成盐的方法分离松香中的树脂酸，在催化剂对甲基苯磺酸存在下与马来酸酐进行Diels-Alder反应合成马来海松酸酐. 当松香、马来酸酐摩尔比为1.9∶1.0,反应温度180℃，反应时间4h时，MPA的收率可达70.3%.

Abstract: Resin acid was separated from rosin through salt formation with cyclohexylamine. In the presence of p-toluene sulfonic acid as a catalyst, resin acid reacted with maleic anhydride by Diels-Alder reaction. The final product of this reaction is maleopimaric acid anhydride. This reaction was carried out under the circumstances that the molar ratio of rosin to maleic anhydride is 1.9∶1.0, reaction temperature is 180℃, and reaction time is 4h. The synthetic efficiency of maleopimaric acid anhydride is 70.3%.

Key words: Diels-Alder reaction , maleic anhydride, rosin, maleopimaric acid anhydride(MPA)
