The molar excess enthalpies and molar excess volumes of carbon tetra- chloride + hexafluorobenzene have been measured at 298.15 K and 308.15 K. The values for the equimolar mixture at 298 15 K are 490 J mol-1 and 0.875 cm3 mol-1 respectively. The results are compared with the values for other liquid mixtures containing a fluorocarbon as one component, and discussed in terms of solubility parameter theory.

Molar Excess Volumes

Molar excess volumes, VE at 298.15 and 308.15 K, molar excess enthalpies HE at 308.15 K, and total vapour pressure at 298.15 and 308.15 K. have been measured for binary mixtures of 1,2-dichloroethane with aromatic hydrocarbons. The VE and HE data for an equimolar mixture at 308.15 K only have been utilized to predict VE, HE, and TSE values (using Sanchez and Lacombe theory) for these mixtures as a function of temperature and composition. The agreement between the predicted and the corresponding experimental values is good so far as VE and HE data are concerned but the same is not true of the TSE values.

Flory’S Theory

Molar excess volumes, [Formula: see text], and molar excess enthalpies, [Formula: see text], of nitrobenzene (i) + benzene (j) + cyclohexane (k), nitrobenzene (i) + benzene (j) + n-hexane (k), and nitrobenzene (i) + benzene (j) + n-heptane (k) ternary mixtures have been determined dilatometrically and calorimetrically as a function of composition at 298.15 K. The data have been analyzed in terms of (i) the graph-theoretical approach and (ii) Flory's Theory. It has been observed that [Formula: see text], data calculated by graph theoretical as well as Flory's approach compare well with their corresponding experimental values. Keywords: molar excess volumes, molar excess enthalpies, specific interactions, molar volume interaction parameter, molar interaction enthalpy parameter.

Flory’S Theory

Molar excess volumes (VEijk) of 1,3-dioxolane (i) + benzene (j) + cyclohexane (k); 1,3-dioxolane (i) + benzene (j) + n-hexane (k); and 1,3-dioxolane (i) + benzene (j) + n-heptane (k) ternary mixtures have been measured dilatometrically as a function of composition at 298.15 K. The observed data have been analysed in terms of (i) Graph theoretical approach; (ii) Flory's theory; and (iii) Lacombe and Sanche's theory of liquid mixtures. It has been observed that VEijk values predicted by graph theoretical approach compare better with the corresponding experimental values than with the VEijk data predicted by other approaches.Key words: molar excess volumes, molar volume interaction parameters, connectivity parameter of third degree 3ξ.
