摘要
本文报道了α-磺基月桂酸及其一些衍生物的制备和基本物理化学性质,以及它们与阳离子表面活性剂复配的混合体系表面活性的研究。结果表明:α-磺基月桂酸异丙酯钠盐表面活性最高,二钠盐的表面活性最低;与十烷基三甲基溴化铵(1:1)的混合物的表面活性比单一表面活性剂高得多,且易溶于水(超过cmc),尤其是二钠盐混合物,具有实际应用意义。
Abstract: α-Sulfolauric acid and some of its derivatives were synthesized and the surface-chemical properties were studied. Among them the ester(i-propyl)sodium salt possessed the highest surface activity and the di-sodium salt the lowest. It was found that their mixtures with decyltrimethylammonium bromide( 1 : 1 )were extremely surface-active in comparison with the single surfactant and still had a good solubility in water(quive ovre cmc ), especially for the disodium salt mixture, being of great significance in practical applications.
