摘　　要：水杨酸在农业和医药领域均有着重要的应用,将水杨酸制备可聚合成季铵盐型阳离子表面活性剂可以进一步提高水杨酸的应用效果。以甲基丙烯酸二甲氨乙酯和环氧氯丙烷酯化改性的水杨酸为反应原料,乙腈为反应溶剂,在70℃的条件下反应12 h,得到可聚合的水杨酸季铵盐。通过对反应条件的探讨,得到最佳反应条件,获得最高收率为62.7%的淡黄色液体产物,并使用傅里叶变换红外光谱对其结构进行表征。Salicylic acid has important application in the fields of agriculture and medicine. The polymerizable salicylic acid quaternary ammonium salt cationic surfactant can improve the application effect of salicylic acid. Dimethylaminoethyl methacrylate epichlorohydrin esterification of salicylic acid was used to synthesize the novel quaternary ammonium salt at 70 ℃ for 12 h. Under the optimal conditions, the pale yellow liquid product was obtained with the highest yield of 62.7%. FT-IR was used to characterize the compound.
