通过最大增溶水量法、电导率法选择合适微乳液体系组分及最佳配比，制备出以仲烷基磺酸钠（SAS60）和壬基酚聚氧乙烯醚（TX-4）为表面活性剂（S）、正丁醇（As）为助表面活性剂、石油醚（O ）为油相的反相（W/O ）型微乳液．考察了高速离心、盐度、温度对其稳定性的影响．结果表明：当正丁醇、仲烷基磺酸钠、TX-4、石油醚的质量比为2．5∶2∶3∶7．5时，可得到稳定的W/O型单相微乳液；该微乳体系具有良好的机械稳定性．盐度在0．6％～0．8％时对该体系几乎无影响，但随着温度的升高稳定性变差．

In this paper an W/O microemulsion that consists of non-ionic surfactant TX-4 , Anionic surfactant SAS60 ,n-butyl alcohol as co surfactant ,petroleum ether as oil phase with increasing water and conductivity was developed .The influences of temperature ,salinity as well as high-speed centrifugation method on the stability of microemulsion systems .The re-sults showed that the stable micro-emulsion (W/O) could be formed ,when the ratio of n-butyl alcohol ,SAS60 ,TX-4 ,petroleum ether was 2 .5∶2∶3∶7 .5 .The micro-emulsion sys-tem had good mechanical stability without phase separation .Salinity has hardly influences on the micro-emulsion regions ,but the micro-emulsion region decreases slightly with tempera-ture .
