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,讨论了不同碳链长度的醇对乙草胺微乳液拟三元相图的影响,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;以正丁醇为助表面活性剂时,正丁醇的质量分数〔m(正丁醇)/m(AEG+AEC+正丁醇)〕对微乳区面积有一个最佳值。 The microemulsion phase behavior of AEG / AEC / acetochlor / water system was studied by quasi-ternary phase diagram method. The effects of different alcohol chain length alcohols Amine microemulsion pseudo-ternary phase diagram of the impact, and measured by conductivity, the acetochlor microemulsion microstructure changes. The results showed that with the increase of carbon chain of co-surfactant, the area of ​​microemulsion of acetochlor microemulsion gradually became smaller and the area of ​​liquid crystal increased from scratch. With n-butanol as cosurfactant , The mass fraction of n-butanol [m (n-butanol) / m (AEG + AEC + n-butanol)] has an optimum value for the area of ​​the microemulsion.
