摘要： 松香酸与三氯化磷反应制得松香酰氯,收率85%以上。松香酰氯与谷氨酸钠进行缩合反应合成了松香酰谷氨酸,通过正交试验优化的合成条件为:松香酰氯与谷氨酸摩尔比为 10.8,反应温度25～30℃,pH 7～8,反应时间2.5 h,以丙酮与水体积比1:1为混合溶剂,收率84%。并对松香酰谷氨酸双钠的表面活性进行了测定。

Abstract: Rosinoyl chloride was prepared from rosin acid and PCl3 at yield over 84%. Rosinoyl glutamic acid was synthesized by condensation of rosinoyl chloride with glutamic acid in 50%aqueous acetone. Orthogonal experiment result shows that the optimum synthetic conditions were as follows: molar ratio of rosinoyl chloride to glutamic acid 1:0.8,reaction time 2.5 h,reaction temperature 25～30℃,pH 7～8, yield 84%. Surfactant properties of sodium rosinoyl glutamate were also determined.

Key words: rosinoyl glutamic acid, rosin acid
