Abstract: The invention relates to a method for separating close-boiling homo and heteroazeotropic mixtures using ionic liquids. The method is superior to conventional extractive rectification in terms of cost-effectiveness and exergetic aspects as a result of the selectivity and the unusual characteristic profile of the ionic liquids.

Abstract: THE INVENTION RELATES TO A PROCESS FOR SEPARATING CLOSE-BOILING, HOMO-AND HETEROAZEOTROPIC MIXTURES BY USING IONIC LIQUIDS. DUE TO THE SELECTIVITY AND UNUSUAL COMBINATION OF PROPERTIES OF THE IONIC LIQUIDS THE PROCESS IS SUPERIOR TO CONVENTIONAL EXTRACTIVE RECTIFICATION FROM THE POINT OF VIEW OF COSTS AND ENERGY.(FIGURE 1)
