Comparative evaluation of liquid–liquid equilibria for extraction of 2,2,3, 3‐tetrafluoro‐1‐propanol from water by a ZIF‐8‐porous ionic liquid

BACKGROUND 2,2,3,3‐Tetrafluoro‐1‐propanol (TFP) is a benign solvent and widely used in the electronics industry as a cleaning agent. Because water and TFP can form an azeotropic mixture, it consumes energy to separate TFP from its aqueous mixtures using conventional distillation. RESULTS In this work, the zeolitic imidazolate framework‐8 porous ionic liquid (ZIF‐8‐PIL) and the ionic liquid (IL) N ‐butyl pyridinium bis(trifluoromethyl sulfonyl)...
