ABSTRACT

Experimental densities for the ternary mixtures x1 1-chlorobutane + x2 n-heptane +( 1- x1 - x2).2-butanone or 2-pentanone and five corresponding binary systems have been measured at T = (288.15 , 303.15 and 313.15) K and atmospheric pressure , using a DMA 5000 Anton Paar densimeter . Excess Molar volumes have been calculated using the measured experimental densities of the pure liquids and mixtures .The VE results were correlated and fitted by the Redlich-Kister equation for binary mixtures and by the Nagata and Tamura equation for ternary mixtures, as a function of mole fraction. Several predictive empirical relations were applied to predict the excess volumes of ternary mixtures from the binary mixing data . Of three fixed composition Ri = x1/x2, the excess molar volumes for the two ternaries are positive over the entire range of composition .
