研究了单（２─乙基己基）磷酸钠盐─醇─有机溶剂─水体系微乳液的形成条件，用稀释法测定了热力学函数△Ｇ０→ｉ，并求得了酸式盐ＮａＨＡ─醇－正己烷－水体系微乳液的结构参数，讨论了有机溶剂、醇、温度对△Ｇ０→ｉ的影响及醇碳链长度与微乳液结构参数的关系。
The conditions for the formation of microemulsion of mono (2-ethylhexyl) phosphate sodium salt-alcohol-organic solvent-water system were studied. The thermodynamic function △ G0 → i was determined by dilution method and the acid salt NaHA-alcohol- The effects of organic solvents, alcohols and temperature on △ G0 → i and the relationship between alcohol-carbon chain length and the structure parameters of microemulsion were discussed.
