Coupling the capabilities of different complexing agents into deep eutectic solvents to enhance the separation of aromatics from aliphatics
(Liquid + liquid) extraction of ethylbenzene from n-octane by using tetrabutylammonium bromide-based deep eutectic solvents (DESs) containing pyridine, ethylene glycol, or a mixture of both complexing agents was investigated at 25 degrees C and atmospheric pressure. The performance of each DES was d...
