EN The interfacial composition, ther mo dy namic prop er ties and struc ture pa ram e ters of the microemulsion systems con tain ing surfactant-like ionic liquid have been investigated with the dilution method of the W/O microemulsions. The interfacial parameters of Xa i , thermodynamic properties K, –Delta Go i o rghtwards arrow and structure parameters Re, Rw, Nd, Ns, Na have been calculated and discussed for microemulsion systems surfactant-like ionic liquid C12mimBr (C14mimBr, C16mimBr) / alcohol / alkane / water. The effects of water content, alcohols, alkanes, salinity and temperature on above parameters were dis cussed. The results show that with the in crease insalinity and the carbon chain length of both surfactant and alcohol, or with the decrease in the carbon chain length of the alkanes, the molar fraction of the alcohol at the interfacial layer (Xa i ) decreases, the formation of the micro - emulsion is more spontaneous in thermodynamics, and the droplets of the W/O microemulsion were enlarged. The size of the microemulsion droplets is sensitive to the water content, and increases significantly with increasing water content.
