摘要
本文以乙二胺、溴代十四烷和顺丁烯二酸酐等为主要原料,通过亲核取代、开环、中和等系列反应合成了一种阴离子型双子表面活性剂GMAS-14,采用红外光谱(IR)对中间体N,N'-双十四烷基乙二胺和目标产物GMAS-14进行了结构表征,并测试了GMAS-14的表面活性和起泡性能.红外光谱结果表明:合成的中间体及终产物的结构与设计相一致,可以确定合成的物质即为目标产物.GMAS-14性能测试表明:在25℃时,GMAS-14的临界胶束浓度cmc为0.048 mmol/L,对应的表面张力(γcmc)为27.5 mN/m;当临界胶束浓度下,10mL的GMAS-14溶液的最大起泡体积为23 mL,泡沫半衰期为590 s,表现出良好的起泡与稳泡性.
Abstract
An anionic gemini surfactant GMAS-14 was synthesized via series of reactions,such as nucleophilic substitution,ring opening and netrualization reaction by using ethylenediamine,1-bromotetradecane and maleic anhydride as raw materials.The structure of N,N'-(2-tetradecyl)-ethylenediamine and GMAS-14 was characterized by infrared spectroscopy (IR),and the surface activity and foaming properties of GMAS-14 were tested.The results of IR showed that,the structure of the intermediate and final products were consistent with the design,and it was determined that the substances were the target products.The performance test of GMAS-14 indicated that,at the temperature of 25℃,the critical micelle concentration (cmc) of the GMAS-14 was of 0.048 mmol/L and the surface tension (γcmc) of the GMAS-14 was of 27.5 mN/m.At the critical micelle concentration,the maximum foam volume of GMAS-14 solution of 10 mL was of 23 mL,and the half-life period of the foam was 590 s,presenting good foaming properties.
