Separate isomers via supercritical gas extraction.

Process for separating isomeric mixtures

A method removing water from aqueous alkali metal hydroxide solutions by contacting the solution with an organic liquid at elevated temperatures and pressures to form an organic liquid-water phase and a hydroxide solution phase and thereafter separating the organic water phase from the hydroxide solution phase.
