摘要
为选择适于甲苯增溶吸收微乳体系,研究了以甲苯为油相、以正丁醇或正辛醇为助表面活性剂分别与典型阳离子、阴离子、非离子表面活性剂形成的微乳液的相行为,用相图法分析了微乳体系的稳定性.以相图微乳区面积为指标,考察了影响微乳液增溶甲苯的因素.结果表明,在实验条件下6种微乳液可以自发形成;以十六烷基三甲基溴化铵为表面活性剂、正辛醇为助表面活性剂、表面活性剂与助表面活性剂质量比为3:2、温度为30℃时,微乳区面积最大(64%),可作为甲苯增溶吸收微乳液.
In order to optimize the absorption microemulsion system for solubilization toluene, the phase behavior of the microemulsion system was investigated in the presence of oil phase （toluene）, typical surfactant （cation, anion and nonionic surfactant）, cosurfactant （n-butanol, n-octanol）. By analyzing phase diagram the stability of the microemulsion system was analyzed. Using phase diagram microemulsion area as index, the factors influencing the solubilization of toluene for microemulsion were investigated. In all six conditions investigated in this study, microemulsion could be formed spontaneously. The optimum absorption microemulsion system for solubilization toluene was cetyltrimethylammonium bromide as surfactant, n-octanol as cosurfactant, and the mass ratio of surfactant with cosurfactant was 3：2 with the temperature 30℃, the microemulsion area were greatest （64%）. It could be the toluene solubilization absorption microemulsion.
