摘　　要：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 results showed that the stable micro-emulsion（W/O）could be formed,when the ratio of nbutyl alcohol,SAS60,TX-4,petroleum ether was 2.5∶2∶3∶7.5.The micro-emulsion system had good mechanical stability without phase separation.Salinity has hardly influences on the micro-emulsion regions,but the micro-emulsion region decreases slightly with temperature.
