Phase diagrams of the LAS/TX-10/butanol/fenobucarb syst em were presented. The weight ratios of LAS to (LAS+TX-10) and butanol to (LAS +T X-10) had a significant influence on the phase region.The higher the ratio of LAS to ( LAS +TX-10),the bigger the liquid crystal region;and the lower the rat io,the bigger the emulsion region.The lower the weight ratio of butanol to ( LAS +TX-10),the bigger the liquid crystal region;and the higher the ratio,the smal ler the region.Microstructure was studied by conductivity measurement.When the w eight ratio of butanol to (LAS+TX-10) was 1,and the weight ratio of LAS to TX- 10 were 1/9 or 6/4,the microstructure underwent a continuous change,namely from W/O structure through bicontinuous structure to O/W structure.When the weight r atio of LAS to TX-10 was 9,there was a liquid crystal region after bicontinuous .
