Liquid-liquid extraction of styrene from ethylbenzene using ionic liquids

The performance of the 3-(2-methoxyethyl)-1-methylimidazolium dicyanamide ([(C2OCH3)MIM][DCA]), 1-(4-methoxy-4-oxobutyl)-3-methylimidazolium dicyanamide ([(C3COOMe)MIM][DCA]) and choline dicyanamide ([Chol][DCA]) ionic liquids (ILs) as alternative solvents in the liquid–liquid extraction of styrene from ethylbenzene was evaluated at temperature T = 298.15 K and ambient pressure. This work is a continuation of selection of [DCA]− based ILs for...
