【摘要】 以AS/C12-4-C12.2Br/ROH/己烷/盐水系统为对象,研究了表面活性剂配比,表面活性剂用量,醇的种类,醇度,盐度等对系统相态的影响,结果显示:AS/C12-4-C12.2Br复配具有较好的协同效应,以AS/C12-4-C12.2Br复配物为表面活性剂所制备的中相微乳液的最佳体积比用单一表面活性剂形成中相微乳液体积大,形成中相微乳液的较佳条件是:以丁醇为助表面活性剂,w(AS)∶w(C12-4-C12.2Br)复配比为10∶1,c(NaCl)=14%∶c(ROH)=4%,中相微乳液的体积达到3.3 mL。更多还原

【Abstract】 The system of（dodecyl sulfonic acid sodium salt）AS/C₁₂-4C₁₂·2Br/ROH/hexane/brine was studied.The influence of mass ratio of surfactant,dosage of surfactant,type and concentration of alcohol and salinity on the phase state was investigated.A higher synergism was observed when combining the C₁₂-4-C₁₂·2Br surfactant with As,and the volume of middle phase microemusion of the mixed surfactant was bigger than that of the single surfactant,The optimal formation conditions of middle phase microemulsions of AS/C₁₂-4-C₁₂·2Br/ROH/hexane /brine were obtained as follows : n-butanol was used as cosurfactant, w（AS） ∶ w(C₁₂-4-C₁₂·2Br)=10 ∶1,c（NaCl）=14%,c（ROH）=4%,and the volume of middle phase microemusion reached 3.3 mL.更多还原
