摘要
以离子液体[bmim]Br/AlCl3作为绿色反应介质,通过脱氢松香酸甲酯芳环上的Friedel-Crafts酰基化反应,合成了12-苯甲酰基脱氢松香酸甲酯,最佳合成条件为:脱氢松香酸甲酯、[bmim]Br、AlCl3、苯甲酰氯的摩尔比1∶4∶8∶8,反应温度40℃,反应时间2h。用IR、MS、NMR和元素分析等方法对目标产物进行了分析和表征。结果表明,该合成方法具有反应条件温和、反应时间短及环境友好等优点。
In the presence of the ionic liquid [ bmim] Br/AlCl3 as green reaction medium and catalyst, methyl 12- benzoyldehydroabietate was synthesized by the Friedel-Crafts acylation reaction on the aromatic ring of methyl dehydroabietate. The optimum synthetic conditions of the target product were found to be as follows： mole ratio of methyl dehydroabietate-to-[ bmim] Br-to-AlCl3-to-benzoyl chloride 1 ： 4 ： 8 ： 8, reaction temperature 40℃, reaction time 2h . The target product was analyzed and characterized by means of IR , MS, NMR and elemental analysis. The results showed that this new method had the advantages of mild condition, short reaction time and environmental benignity.
