DENSITIES AND EXCESS MOLAR VOLUMES OF THE TERNARY MIXTURE (1-BUTANOL PLUS N-HEXANE PLUS 1-CHLOROBUTANE) AT 298.15 AND 313.15 K - APPLICATION OF THE ERAS MODEL

Densities of the liquid mixtures (n-hexane + 1-chlorobutane) and (1-bu tanol + n-hexane + 1-chlorobutane) have been measured by the vibrating tube technique at 298.15 K and 313.15 K. With these densities, excess molar volumes were calculated. An extended version of the so-called E RAS model has been used for describing VE Of the complete ternary syst em at 298.15 K. Qualitatively the ERAS-model gives an adequate represe ntation of this system, being similar the shapes of both the experimen tal and the predicted curves. (C) 1998 Elsevier Science B.V.
