新型基于水杨酸单甘油酯阳离子表面活性剂的制备

摘要

The ring-opening compound of epichlorohydrin was reacted with salicylic acid to synthese the esterification product ,and then the product was reaction with triethylamine to obtain the novel cationic surfactant .The optimum synthetic conditions of the surfactant were studied .The results show that the yield of the product was 84.6%when the reaction was processed in ethanol for 16 h at 70 ℃.%环氧氯丙烷与水杨酸开环酯化后与三乙胺反应，制备一种新型的水杨酸单甘油酯阳离子表面活性剂，探讨了最佳合成条件。结果表明，以乙醇为反应溶剂，在70℃反应16 h后经结晶，收率为84．6％。
