Abstract: PURPOSE: To simplify a raffinate fractionating by separating a solvent remainder incorporated in a paraffin based hydrocarbon at an auxiliary fractionating column arranged at an upper part of a solvent influent tray of an extractive distillation column. CONSTITUTION: A starting material to be separated in a liq. state is introduced to an intermediate part of the extractive distillation column 2 provided with the tray, etc., by interposing a conduit. The solvent is introduced to the extractive distillation column 2 by interposing the conduit 3 and the olefin is absorbed to the solvent when the solvent is made to flow downward by interposing an incorporated member of the column. The auxiliary fractionating column 4 is arranged at an upper part of a solvent supply tray at the upper part of an influent point of the conduit 3, and a paraffin vapor rising from the extractive distillation column 2 reaches directly the auxiliary fractionating column 4.  In this case, the solvent remainder supplied by interposing the conduit 16 and present in the parrafin by reflux is made to flow, and the parrafin is discharged in a pure state by interposing the conduit 15 through an overhead of the column.
