Molar excess volumes for the binary mixtures of cyclohexanone with benzene and some monosubstituted benzenes, namely, toluene, ethylbenzene, isopropylbenzene, tertiary butylbenzene, chlorobenzene, bromobenzene, iodobenzene, N,N-dimethylaniline, nitrobenzene, benzaldehyde, and benzonitrile have been calculated from the precise and accurate experimental density data at 298.15 K over the entire composition range. The results have been discussed in terms of the strength of molecular interactions in the binary mixtures.

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.

Densities at 20 °C and molar excess volumes calculated from them are reported in the work for the mixtures of the substances: propionic acid-n-heptane, propionic acid-benzene, trifluoroacetic acid-benzene, propionic acid-cyclohexane, acetic acid-cyclohexane, acetic acid-trifluoroacetic acid, acetic acid-propionic acid, and propionic acid-trifluoroacetic acid. For the last system mentioned, a strange dependence of excess volume on composition was found which is noted for three local extremes. The dependences of excess volume on composition are correlated by the Redlich-Kister polynomial.

Molar excess volumes of binary mixtures of tetrahydrofuran with n-propylbenzene, isopropylbenzene, 1,3,5-trimethylbenzene, 1,2,3,4-tetramethylbenzene, diphenylmethane, n-hexane, n-octane, 2,2,4-trimethylpentane, n-nonane, 3,3-diethylpentane, n-dodecane, 2,2,4,6,6-pentamethylheptane, cyclohexane, and methylcyclohexane at 313.5 K have been computed from the experimental density data. The systematic variation of VE with the change in size, substitution, and molecular geometry of the hydrocarbon has been discussed.
