摘要
本文系统地研究了羧酸钠同系物水溶液的表面化学性质。结果表明:由于水解生成自由羧酸,羧酸钠与同碳氢链长的一般表面活性剂相比,有较高的表面活性;首次在理论规定条件下计算了吸附量,由此得出表面层分子排列情况,又初步研究了羧酸钠-烷基季铵盐混合体系,表明羧酸钠中加入季铵盐可大大提高体系活性,但却降低了起泡性。
Abstract: The surface-chemical properties alkylcarboxylates of three homologous aqueous solutions have been studied systematically. It is shown that the alkylcarboxylate,owing to its hydrolysis in the aqueous solution to form the free carboxylic acid,has a higher surfcee activity than the common synthetic detergent with the same HC chain. The surface adsorption has been calculated under the conditions stipulated by theory for the first time, and then the moecular arrangement in the surface layer may be illustrated.The preliminary study of some characteristics of the mixed alkylcarboxylate-alkyltrimethylammonium systems has also been made.
