ABSTRACT
Mixed systems containing fluorocarbons (FC) phase separate below certain temperatures. The liquid-liquid coexistence curves show upper critical solution temperatures (Tc/K), that depend on the nature of the components. In this work we report the phase separation measurements of mixtures obtained from short chain linear perfluoroalkanes (perfluorohexane, perfluoroheptane, and perfluorooctane) with some n-alkanes, cyclohexane, benzene, ethers and chlorinated solvents. The results are discussed in terms of the chemical nature and polarizability of the components.
