Abstract

Abstract Alkane and α-olefin sulfonates can be used to produce optimal microemulsion formulations having very high salinity tolerance (including divalent ion) while maintaining large solubilization parameters and low inter-facial tensions (IFT's). Such molecules require elevated temperatures or higher alcohol concentrations to suppress liquid crystal formation. As in other species, solubilization is inversely related to width of the three-phase regime, and IFT and solubilization are strongly coupled.
