摘　　要：以十二烷基二甲基甜菜碱、十二烷基苯磺酸钠、十二烷基氯代吡啶和异十八醇聚氧乙烯 (15 )醚为乳化剂 ,制备了几种不同的煤油 水乳状液 ,探讨了同种表面活性剂在不同浓度下 ,煤油 水的比为 1∶1(V V)的乳状液中富油相 (上相 )和富水相 (下相 )的电导率变化规律 ,以及不同表面活性剂在相同浓度下 ,体系富油相和富水相的电导率变化规律 ;并且测定了不同表面活性剂复配后 ,体系富油相和富水相的电导率变化 ,从中找出了表面活性剂浓度、种类及复配类型对乳状液稳定性的影响规律 。It was studied on the system of kerosene water emulsions, the surfactants were SDBS, DPEO, C 12 BE and CPDC. Under the same conditions,the different types and concentrations of surfactants were determined emulsions with different stabilities.The electrical conductance was measured in the upper and the lower part of the emulsion respectivity, the variational curves of electrical conductance virus time were achieved, in order to study the stabilities of these emulsions.
