| 摘 要： | 研究了阴离子表面活性剂正十二烷基磺酸钠(C12)与两性离子表面活性剂十二烷基二甲基氧化胺(OB-2)复配体系形成胶束能力和降低表面张力的协同增效作用,发现C12与OB-2摩尔比为6∶4~3∶7时增效作用明显。并考察了NaC l对复配体系表面活性的影响,结果表明,加盐能导致复配体系表面活性的提高,在NaC l含量为3%~4%时,对复配体系粘度有明显增强作用。

| Abstract: | The formation of ability of micelle,the ability of reducing surface tension and foaming perfermance has been investigated for the mixed system of anionic(C_(12)) and zwitterionic(OB-2) surfactant.It is found that when the mole ratio of C_(12) to OB-2 is about 6∶4～3∶7,the surface activity shows a maximum.The influence of NaCl on surface properties of the mixed system has also been studied.The surface activity is enhanced with the increase of NaCl concentration.It is also found that the viscosity of mixed system is enhanced when the NaCl concentration is 3%～4%. |

| Keywords: | C_(12)/OB-2 mixed system critical micell concentration surface tension |
