微乳液形成的必要条件为π_δ-σ_((O/W)α) ＞0，充分条件为π_O~′(?)π_W~′或者σ_(O/W)(?)σ_(W/M)。本文研究的体系为AS/C_4H_9CH/C_8H_(18)/H_2O和SDS/C_4H_9OH/C_8H_(18)/H_2O。当油含量增加时，增大丁醇在界面膜上解吸，使得σ_((o/w)α)数值明显上升，不利于微乳液生成，似三组分相图上微乳液区域面积减少，甚至消失。温度影响取决于增加膜压和降低膜强度的综合结果。对SDS体系，在0～60℃范围内，区域总面积A_t增加。对AS体系，t＜30℃，A_t随着温度增加；t＞30℃，温度对A_t影响甚微。
The necessary condition for the formation of microemulsion is π_δ-σ_ (O / W) α)> 0, and the sufficient condition is π_O ~ (?) Π_W ~ ’or σ_ (O / W) (?) Σ_ (W / M). The system studied in this paper is AS / C_4H_9CH / C_8H_ (18) / H_2O and SDS / C_4H_9OH / C_8H_ (18) / H_2O. As the oil content increases, desorption of butanol on the interface membrane increases, making the value of σ_ ((o / w) α) increase obviously, which is unfavorable to the microemulsion formation. disappear. The temperature effect depends on the combined result of increased membrane pressure and reduced membrane strength. The SDS system, in the range of 0 ~ 60 ℃, the total area A_t increased. For AS system, t <30 ℃, A_t increases with temperature; t> 30 ℃, temperature has little effect on A_t.
