摘要：

采用电导法研究了以二(2-乙基己基)琥珀酸酯磺酸钠(AOT)为表面活性剂、庚醇和癸醇分别与甲苯的混合溶剂为油相的反相微乳液体系在有无添加剂氯化钠时的电导行为。 结果表明，甲苯对水/AOT/癸醇体系电导渗滤有明显的抑制作用，而对水/AOT/庚醇体系没有影响；添加氯化钠对水/AOT/庚醇（癸醇）/甲苯体系的电导率基本无影响。

Abstract:

The conductivity behaviors of water-in-toluene-alkanol(heptanol, decanol) reverse microemulsions stabilized solely by sodium bis(2-ethylhexyl) sulfosuccinate(AOT) with and without the additives(sodium chloride) were investigated through conductance measurements. The results showed that the percolation phenomenon was apparently inhibited by toluene in the water/AOT/decanol system, while no effect in the water/AOT/heptanol system. The conductance of water/AOT/heptanol/toulene and water/AOT/decanol/toulene systems had a hardly change in the present of sodium chloride.

Key words: alkanol, toluene, percolation, bis(ethylhexyl) sulfosuccinate, additives
