Abstract: PROCESS FOR WORKING UP A BOTTOM STREAM WHEREIN HIGH BOILERS AND IONIC LIQUID FROM AN EXTRACTIVE RECTIFICATION IN WHICH THE IONIC LIQUID IS USED AS ENTRAINER. THE PROCESS INCLUDES FEEDING THE BOTTOM STREAM TO AN EVAPORATION STAGE WHICH IS OPERATED AT A PRESSURE OF LESS THAN 0.05 MPA (500 MBAR) OR TO A STRIPPER WHICH IS OPERATED THROUGH USE OF INERT GAS OR STEAM, AND THE MAJOR PART OF THE HIGH BOILER PRESENT IS SEPARATED OFF IN VAPOR FORM FROM THE IONIC LIQUID.
