CTAB/正丁醇/正庚烷/水微乳体系稳定性研究

制备了十六烷基三甲基溴化铵(CTAB)/正丁醇/正庚烷/水体系拟三元相图；通过电导法确定了十六烷基三甲基溴化铵(CTAB)/正丁醇/正庚烷/水微乳体系结构；研究了温度、酸度对微乳体系稳定性的影响。结果表明，在较大的表面活性助剂与表面活性剂的质量比值范围内（w(乳化剂)=m（C4H9OH）/m（CTAB）），体系能在较大的组成范围内形成微乳区,该微乳区对温度变化不敏感。随着体系水相酸度的增加，微乳体系的含水量呈不规则变化。

Stabilization of CTAB/C4H9OH/C7H16/H2O micro-emulsion system

Phase diagrams of the pseudo-ternary -component of CTAB/C4H9OH/n-C7H16/H2O system were plotted by the dilution method. The structures of micro-emulsions in the system of CTAB/C4H9OH/n-C7H16/H2O were determined by conductance measurement. The effect of temperature and acidity on micro-emulsion was evaluated. The result indicates that micro-emulsion regions can be formed within larger composition variation of w(Emulsifier)=m（C4H9OH）/m（CTAB） value (the mass ratio of co-surface and surface). In addition, the micro-emulsion regions are insensitive to temperature change. With increasing aqueous acidity, the water content of the micro-emulsion system shows irregular changes.
