Using gasliquid chromatrography to choose solvents for separation of biazeotropic benzene – perfluorobenzene mixture by extractive rectification

Abstract

Gas-liquid chromatography was used for estimating the selectivity of solvents for the separation of biazeotropic benzene - perfluorobenzene mixture based on extractive rectification.The selected optimal solvents enable two theoretically feasible variants of the mixture separation
