Liquid liquid equilibrium studies have been carried out for five multicomponent systems comprising aromatics, paraffins and selected solvents (tetraethylene glycol, sulfolane, dimethyl sulfoxide, N-methylpyrrolidone and trimethyl phosphate). The experimental equilibrium data were fitted by empirical correlations suggested by Hand, Othmer-Tobias, Bulatov-Yachmenev and Rod. The best fit was obtained with the relation by Rod. The solvent capacities and selectivities are also compared.
