Experimental and Theoretical Studies on the Effectiveness of Phosphonium-Based Ionic Liquids for Butanol Removal at T = 298.15 K and p = 1 atm

Biobutanol obtained via an acetone–butanol–ethanol (ABE) fermentation process is now considered a potential biofuel. In recent times low density phosphonium cations were found to remove butanol from aqueous solutions. In this regard, low density phosphonium-based ionic liquids (ILs) trihexyl(tetradecyl)phosphonium dicyanamide [TDTHP][DCA] and trihexyl(tetradecyl)phosphonium decanoate [TDTHP][DEC] have been used for the separation of 1-butanol...
