摘    要:By the orthogonal design,the optimal formation conditions for the middle-phase microemulsions in the system dioctadeeyldimethylammornum chloride (DODMAC)/ sodium dodecyl sulfate (SDS)/n-butanol/n-hep-ane/brine were obtained as follows.Investigations have been made on the effects of the concentrations of NaCl and n-butanol(1.0%-14.0%),the rantos of W to Wshs and the kinds of alcohols (n-propanol,n-butanol,and n-pentanol) on the formation,the phase behavtour,the ultralow interfacial tensions,the optimal salinity (S*),and the length of salinity (S).Some rules and data were worked out about the formation and characteristics of the middle-phase microemulsions.The mi-crostruenres of the middle-phase microemulsions were also studied by using FT-IR,ESR,and freeze fracture electron microscopy techmques The results from the three methods show that the microstructures of the middle-phase mi-croemnlsions undergo the change from O/W to bicontinuous(B C.) and to W/O.The distribution rule of the orga-mzed molecule ass
