Abstract

A process of extractive distillation of a mixture of interchangeable organic compounds, whose procedure consists of being able to contact said mixture in contact with a selective solvent in an extractive distillation column, to increase the volatility difference of said compounds and extractively distill said mixture in presence of said selective solvent to form a head stream comprising the most volatile of said compounds and a bottoms stream comprising the least volatile of said compounds and said selective solvent and to condense at least a part of said head stream to form a reflux stream that is returned to the column, said process being characterized in that the reflux ratio is regulated to maintain two non-miscible liquid phases only in the upper part of said column, said two non-miscible liquid phases being a phase rich in solvent and a phase rich in components of the feed material.
