Abstract
A study is performed of using quinolinium salt as a separating agent for double azeotropic mixtures in the process of extractive distillation. Gas chromatography is employed to study the liquid–vapor equilibrium in a methanol–benzene–chloride N-benzylquinolinium system at 101.3 kPa and different concentrations of organic salt. It is established that a 0.25 concentration (in mole fractions) of chloride N-benzylquinolinium or more is needed to destroy the azeotrope and separate the mixed solvent into components.Keywords
