摘　　要：季铵盐阳离子表面活性剂在造纸工业中应用广泛,它们是一种常用的纸张柔软剂。为了获得一种环境友好,柔软性能更佳的柔软剂,以十二烷基二甲基胺、环氧氯丙烷和己二酸为反应原料,制备了一种新型的双酯类的双阳离子表面活性剂反应产物,用傅里叶变换红外光谱进行特征基团的表征,并对这种双酯双阳离子表面活性剂的纸张柔软效果进行了系统的研究。Quaternary ammonium cationic surfactants have very important application in the papermaking industry, which is a series of important paper softening agents. In order to obtain an environment-friendly paper softening agent, a novel diester gemini quaternary ammonium salt cationic surfactant has been prepared. Dodecyldimethyl amine, epichlorohydrin and adipic acid were used as raw materials to synthesize the surfactant, and Fourier transform infrared spectroscopy was used to characterize the groups in reaction product. Moreover, the softening effect of the diester gemini quaternary ammonium salt cationic surfactant was studied in detail.
