表面活性剂和醇对中相微乳状液相行为的影响

Effect of Surfactants and Alcohol on Middle Phase Microemulsion Behavior

用均匀实验设计法求得阴离子表面活性剂十二烷基硫酸钠（ＳＤＳ）／阳离子表面活性剂十六烷基三甲基溴化铵（ＣＴＡＢ）／正丁醇／正庚烷／盐水体系中相微乳状液形成的最佳条件．系统研究了ＮａＣｌ浓度、ＳＤＳ和ＣＴＡＢ摩尔比、正丁醇浓度。

Sodium dodecyl sulfate(SDS) and cetyltrimethylammonium bromide(CTAB) can form the middle phase microemulsion in the present of alcohol,heptane and brine.Using uniform design,the best conditions of microemulsion forming are found out,and the influence of molar ratio of SDS to CTAB,salinity,concentrations and kinds of alcohol on the formation and characteristics of middle phase microemulsion is investigated.
