In this work, separation of aromatic hydrocarbons from aromatic/aliphatic mixtures by deep eutectic solvents (DESs) at room temperature was developed. It was found that DES formed by levulinic acid as hydrogen bond donor and tetrabutylphosphonium bromide (TBPB) as hydrogen bond acceptor could efficiently separate aromatic hydrocarbons from aromatic/aliphatic mixtures. Levulinic acid/TBPB mole ratio,...
