ABSTRACT
New vapour-liquid equilibrium data for binary and ternary mixtures formed by dibutyl ether (DBE), toluene and cyclohexane at 313.15 K have been measured. A static method using an isothermal total pressure cell (Van Ness' technique) has been employed. The systems studied presented a slight deviation from ideal behaviour. None of them show azeotrope. The VLE data have been satisfactorily correlated with the equations of Margules,Wilson, NRTL and UNIQUAC for binaries andWohl expansion,Wilson, NRTL and UNIQUAC for the ternary system. Predictions with UNIFAC group contribution methods are included.
