ABSTRACT:
A solvent system composed essentially of sulfolane and a ketone, e.g., sulfolane and methyl ethyl ketone is employed in a liquid-liquid extraction operation to separate a low boiling olefin, e.g., pentene-2, hexene-1, octene-1, etc., from a corresponding close boiling paraffin, e.g., n-pentane, n-hexane, and n-octane, respectively, and wherein solvent is recovered by employing a portion thereof in a drying or stripping column.
