醇对乙草胺微乳液相图的影响

用拟三元相图法研究了醇醚糖苷（AEG）/醇醚羧酸盐（AEC）/醇/乙草胺/水体系的微乳液相行为，讨论了不同链长的醇对乙草胺微乳液拟三元相图相图的影响，并通过电导率测定研究了乙草胺微乳液的微观结构转变。结果表明：随着助表面活性剂醇碳链的增长，乙草胺微乳液的微乳区面积逐渐变小，而液晶区从无到有并逐渐增大；固定醇的种类为正丁醇时，醇的含量对微乳区面积有一个最佳值。

Effect of Alcohol on Phase Behavior in Acetochlor Microemulsion

The phase behavior of the microemulsion for the quaternary system of the alkylethoxyglucoside (AEG) / alkylethercarboxylate (AEC) / alcohol / acetochlor / water has been studied with ternary phase diagram, the effects of different alcohols and different alcohol-contents on acetochlor microemulsion were discussed and transformation of microstructure of the acetochlor microemulsion was studied by means of conductivity measurement. The results show that the area of microemulsion region decrease as the carbon chain of alcohol molecules increasing, and the liquid crystal region form and increase. When alcohol is n-butanol, the biggest microemulsion region area is corresponds to a certain content of n-butanol.
