摘要
以24,-二异氰酸酯甲苯、N,N-二甲基乙醇胺、溴代烷等为原料合成了一种新的季铵盐型双子表面活性剂。考察了季铵盐型双子表面活性剂的表面活性,并与常用阳离子表面活性剂比较。结果表明,当溶液的表面张力达40 mN/m最低值时,季铵盐型双子表面活性剂的临界胶束浓度比常用阳离子表面活性剂的临界胶束浓度低1个数量级,说明季铵盐型双子表面活性剂有较高的表面活性,应用前景广阔。
A novel Gemini surfactant was synthesized using 2,4 - diisoeyanatetoluene,N,N - dimethylethanolamine,bromoalkane as raw materials. The surface activity of the Gemini surfactant was examined and compared with the conventional cationic surfactant. The result showed that when the surface tension of the so- lution reached the minium value of 40 mN/m,the CMC al cationic surfactant by 1 order of magnitute showing thus had brilliant prospects in future application. of Gemini surfactant was lower than that of convention- Gemini surfanctant had higher surfactant activity and
