协同效应在WO型微乳液中的作用

Effect of Synergism on Microemulsion (W/O)

本文通过拟三元相图、增溶、电导和表面张力测定等方法,研究了烷基羧酸盐(CnH_(2n+1)COONa)与十六烷基三甲基溴化铵(CTAB)复配在正戊醇存在下对煤油—水体系W/O型微乳液形成的协同效应,发现在整个复配范围内同时出现协同效应和反协同效应。而且,发生协同效应的复配范围是在羧酸盐的高比例区,此时,体系的W/O型微乳区域面积扩大。

The synergism on formation of W/O type microemulsion of kerosenewater system by complex formulation of alkyl carboxylates (C_nH_(2n+1)COONa) and hexadecyl trimethyl ammonium bromide(CTAB) when the n-pentanol existing were investigated with pseudo-ternary phase, method of solubilized effect, method of conductivity and measuring surface tension in this paper. The synergism and anti-synergism were found in all ratio ranges of carboxylates to CTAB. The results indicate that the synergism takes place in high ratio region of carboxylates and the area of forming W/O type microemulsion in this system increases.
