摘　　要：制备了N-牛脂基-1,3-丙撑二胺基氯乙酸钠(N-EDSC),通过单因素实验和正交试验研究了合成N-EDSC的最佳条件:n(SD):n(N-ED)=1:1,催化剂的质量分数为2.5%,反应温度为70℃,反应时间为15 h。通过红外光谱对目标产物N-EDSC的结构进行分析,表明目标产物确为N-EDSC;对N-EDSC水溶液的表面张力进行测试,表明N-EDSC具有强亲水性,有利于其在水性体系中的分散。通过吸光度和粒径分析N-EDSC在水性油墨中的分散性,结果显示在水溶性油墨色浆中添加N-EDSC的质量分数为1.2%时,分散效果较佳。N-tallow-1,3-propylenediamine sodium chloroacetate(N-EDSC)was prepared,and the optimal conditions for synthesis of N-EDSC were studied through single factor experiment and orthogonal experiment.The optimum conditions were n(SD):n(N-ED)=1:1,the amount of catalyst of 2.5%,the reaction temperature of 70℃,and the reaction time of 15 h.Analysis of the structure of the target product N-EDSC by infrared spectroscopy showed that the target product was indeed N-EDSC.The surface tension test of the N-EDSC aqueous solution showed that N-EDSC had strong hydrophilicity,which was beneficial to its use in aqueous systems.The dispersibility of N-EDSC in water-based inks was analyzed in terms of absorbance and particle size,and the results showed that the dispersibility was better when the addition of N-EDSC was 1.2%in water-soluble ink.
