W/O型环己烷微乳液的研究

Study on W/O Cyclohexane Microemulsion

考察了不同种类醇、表面活性剂用量和配比对环己烷微乳液增溶水量和电导率的影响;探讨了电解质对环己烷微乳液相行为的影响。实验结果表明:正戊醇为最佳助剂,助剂与表面活性剂碳链比适中更易形成微乳液;随着表面活性剂质量分数的增加,体系增溶水量增大,电导率下降;电解质对环己烷微乳液有重要的影响,随着NaC l质量分数的逐渐增大,体系从下相微乳液过渡到中相微乳液,进而形成上相微乳液。

The effects of different kinds of alcohol , amount and ratio of surfactants on the amount of solubilized water and conductivity of cyclohexane microemulsion were investigated at the same time. The effect of electrolyte on phase behavior of cyclohexane microemulsion was discussed. The results show that n -pentanol is optimal assistant ,when the moderation carbon chains ratio of assistant and surfactant are preferential for the formation of microemulsion. Along with rise of surfactant weight fraction , the amount of solubilized water increases and conductivity decreases ; The effect of electrolyte is also important, the system of upper - phase microemulsion is gradually formed from down - phase to middle - phase microemulsion with increasing of NaCL weight fraction.
