CTAB～n-C_4H_9OH/c-C_6H_(12)/H_2O体系W/O微乳液稳定性研究

Study on the Stabilizing Conditions of W/O Microemulsion for CTAB～n-Butanol/Cyclohexane/Water System

对CTAB～n＿C4H9OH/c＿C6H12/H2O体系微乳液的相组成和性质进行研究。结果表明,当CTAB与n＿C4H9OH质量比为2∶3时,具有较宽范围的W/O微乳液相区域,且该微乳液体系对温度变化不敏感,当pH≥2时,有较强的pH值稳定性,并探讨了液晶相出现的原因。

In this paper water-in-oil microemulsion phase and properties of CTAB～n-butanol/cyclohexane/water system were studied.It shows that when CTAB and n-butanol is in weight ratio of 2∶3,this water-in-oil microemulsion system has extansive and stable microemulsion phase regions which is not changed at varying pH value from 2 to 14,and this system is insensitive to temperatures.At the same time,the occuring reasons of fluid crystals was analyzed.
