Liquid-Liquid Equilibria for the Ternary Systems of Perfluamine plus Hydrofluoroether plus Benzene, Toluene, or Xylene at 298.15 K or 313.15 K

Abstract

A fluorous biphasic system consists of a fluorinated solvent and an organic solvent. The mutual solubility data of fluorous biphasic systems were analyzed for common organic solvents such as benzene, toluene, and xylene with perfluamine. Fluorous/organic amphiphilic ether solvents such as HFE7300 and HFE7500 were added to the fluorous biphasic system. The equilibrium tie lines for ternary systems were determined at two different temperatures, and the equilibrium data sets were correlated with the nonrandom two-liquid and universal quasichemical models.
