Phase Separation in Binary Mixtures Containing Linear Perfluoroalkanes

Mixed systems containing fluorocarbons (FC) phase separate below certain temperatures. The liquid−liquid coexistence curves show upper critical solution temperatures ( T c ) 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.
