Abstract

Results are reported on the thermal analysis of biphasic hexadecane/n-hexanol/K-oleate and water samples with composition falling outside the domain of existence of homogeneous and isotropic microemulsion systems. The very first appearance of macroscopic phase separation of the samples into an isotropic w/o microemulsion and a birefringent mesophase, was investigated by differential scanning calorimetry (DSC). The partitioning of the hydrocarbon and of the “free” water in the two phases of biphasic samples was analyzed.
