Theoretical and Experimental Studies on Extraction of Carboxylic Acids from Aqueous Solution Using Ionic Liquids

Abstract—This study is aimed to investigate the ability of ionic liquids (green solvents) for the recovery of various acids such as Itaconic-, Glycolic-, Tartaric-, Oxalic-, Propionic-, Lactic-, Acetic-, Acrylic-, Glyoxylic- and Nicotinic- acids from aqueous solutions as simulated fermentation broths. Selectivity and capacity of ionic liquids for extraction of acids are predicted by using the COSMOtherm software version C3.0 Release 12.01. C4MIMTF2N is used as a model ionic liquid to verify the extraction ability of ionic liquids with experimental results. The effects of solvent, anions and cations of ionic liquids, and the length of carbon chain on the selectivity and capacity are also determined. The results indicate that sulfate anions in imidazolium based ionic liquids are comparatively better than other anions available in the database. It is also observed that with the increase in the length of carbon chain the selectivity decreases where as the capacity increases.

Index Terms—Ionic Liquids, extraction, carboxylic acids, equilibria, cosmotherm.
