IONIC LIQUIDS AS SELECTIVE ADDITIVES FOR THE SEPARATION OF CLOSE-BOILING OR AZEOTROPIC MIXTURES

摘要

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.
