摘要
Abstract
Hexadecyl dimethyl tertiary amine and octadecyl dimethyl tertiary amine were separately used as starting material and to be reacted successively with hydrochloric acid and epichlorohydrin to prepare two intermediates,N -(3 - chloro - 2 - hydroxy)propyl - N,N - dimethyl hexadecyl ammonium chloride and N -(3 - chloro - 2 - hydroxy)propyl - N,N - dimethyl octadecyl ammonium chloride. Then ethylene di - amine reacted with the two intermediates successively in presence of sodium carbonate to obtain the product asymmetric Gemini surfactant (symbolized as 16 - X - 18). The intermediates and the product were characterized by IR and 1 H NMR as well as the surface activities of 16 - X - 18 were measured by conductivity method. Results showed that Krafft point of the product is below 0 ℃,and its cmc at 25 ℃ is 2. 935 × 10 - 5 mol/ L. The degree of combination with the counter - ion decreases as the temperature rises.关键词
