摘　　要：分别用妥尔油脂肪酸FA1和FA2与羟乙基乙二胺、3-氯-2-羟基丙磺酸钠反应,合成了妥尔油酸咪唑啉磺酸盐TOS-1和TOS-2,测试了物化性能。研究表明,TOS-1的表面张力γ_(cmc)为29.65 mN/m,临界胶束浓度cmc为8.75 mg/L,TOS-2的表面张力γ_(cmc)为29.64 mN/m,临界胶束浓度cmc为23.77 mg/L,TOS-1的临界胶束浓度小于TOS-2,润湿性、乳化性能均优于TOS-2,泡沫低于TOS-2,是一类稳泡性较好的表面活性剂。Tall oil-based hydroxyethyl imidazoline sulfonate(TOS-1)and TOS-2 was synthesized by Tall fatty acids FA1 and FA2,hydroxy ethylene diamine and sodium 3-chloro-2-hydroxypropanesulfonate,the physical and chemical properties were tested.The results showed that the surface tension cmc of TOS-1 was 29.65 mN/m,the critical micelle concentration cmc was 8.75 mg/L.The surface tension cmc of OS-2 was 29.64 mN/m,the critical micelle concentration cmc was 23.77 mg/L,and the critical micelle concentration of OS-1 was lower than that of OS-2.The wettability and emulsifying performance of TOS-1 are better than TOS-2,and the foam level of TOS-1 is lower than that of TOS-2.It is a kind of surfactant with good foam stability.
