ABSTRACT

The excess molar volume, VE and speed of sound u of ternary {1-methyl pyrrolidin-2-one (i) + benzene (j) + methyl benzene, or cyclohexane (k); 1-methyl pyrrolidin-2-one (i) + methyl benzene (j) + cyclohexane (k)} and the excess molar volume, VE, excess molar enthalpy, HE, and speed of sound, u, of binary {1-methyl pyrrolidin-2-one (i) + benzene, or methyl benzene, or cyclohexane (j)} mixtures have been measured over the entire range of composition at T = 308.15 K. Speeds of sound of binary and ternary mixtures data have been utilized to determine the excess isentropic compressibility, kappaE . The observed VE, HE, and kappaE results of binary and ternary mixtures have been analyzed in terms of the (1) Graph theory and (2) Prigogine-Flory-Patterson theory. It has been observed that VE, HE, and kappaE values predicted by Graph theory for binary and ternary mixtures compare well with their corresponding experimental values.
