一种羧酸盐型双子表面活性剂的合成及性能研究
Study on synthesis and properties of a kind of carboxylate gemini surfactant
摘要
Abstract
A kind of carboxylate gemini surfactant CGS - 2 was synthesized by using lauryl amine, dibromoethane and succinic anhydride as starting materials. Structure of the synthetic product was characterized by IR,1HNMR and elemental analysis. Surface activity of the CGS -2 product was investigated. Results showed that,under the optimum synthesis conditions,yield of the intermediate achieves 52.4% ,and the yield from the intermediate to the final product CGS - 2 achieves 91. 5%. Critical micelle concentration of the CGS - 2 product solution achieves 2. 23 × 10-5 mol · L-1 .which is lower than that of the conventional surfactants with order of magnitude of 3. Surface tension of the product can be minimized to 29. 49 mN · m-1.关键词
