摘要：以松香、富马酸、亚硫酰氯为原料,制备了富马海松酸酰氯。以富马海松酸酰氯为油 溶性单体,二乙烯三胺为水溶性单体,在稳定的乳化体系中两种单体在两相界面发生缩聚反 应,生成立体网状结构的高分子聚合物囊壳,形成包油微胶囊。确定了富马海松酸酰氯制备反 应的最佳条件和微胶囊化过程中的最佳乳化条件、成囊条件及最佳芯壁比。实验得出当芯壁比为7:1。乳化 剂加入量为6％,乳化过程搅拌速度3000 r／min,成囊过程搅拌速度800 r／min时,得到微胶囊包埋率为 85．4％,包埋度为74．7％。
Fumaropimaric acid chloride was prepared through Diels-Alder reaction and chlorination with rosin, fumaric acid and SOCl2 as raw materials. Using fumaropimaric acid as water-soluble monomer and diethylenetriamine as oil-soluble monomer, interracial polymerization took place at the interface of two phases to produce the threedimensional reticulate polymer wall, and oil was enveloped in microcapsules. The conditions of preparation of fumaropimaric acid chloride, emulsification, microencapsulation, and the ratio of core to coating were optimized. At the ratio of core to coating 7 ： 1, emulgator dosage 6%, and stirring speed 3 000 r/min for emulsification and 800 r/min for microencapsulation, the embedding rate and embedding degree of microcapsules were 85.4% and 74.7%, respectively.
