Topological studies of the molecular species that characterize lower alkanol + methylene bromide mixtures: molar excess volumes and molar excess enthalpies

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.

Parameter Theory

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.

Theoretical Analyses

Molar excess volumes and molar excess enthalpies for various (i + j) binary methylene bromide (i) + aniline or N-methyl aniline and + N,N-dimethyl aniline (j) mixtures have been determined as a function of composition at 308.15 K. The data have been analysed in terms of the graph-theoretical approach and Sanchez and Lacombe theory. The graph-theoretical analyses of VE data suggest that aniline, N-methyl aniline, and N,N-dimethyl aniline exist as equilibrium mixtures of monomer and dimer and that these mixtures contain 1:1 molecular complexes. The IR studies lend further credence to the nature and extent of interaction along with support for the proposed structure of molecular species in these mixtures.

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.
