Excess volumes of mixing, VE, for binary mixtures of eyelohexanone with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-dodecane, n-tetradecane, and n-hexadecane at 25 °C were determined from the precise and accurate experimental density data. The sign and magnitude of VE were discussed in terms of the strength of the unlike interactions present in the binary mixtures.Excess volumes of mixing of equimolar concentration [Formula: see text] were also obtained. Attempts were made to interpret [Formula: see text] in terms of the size and polarity of the constituent molecule. The two effects could not be separated, but a good linear relation between [Formula: see text] and the solubility parameter was found.

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.

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.

Densities of binary mixtures of 2-methoxyethanol (2-MeO-EtOH) and 2-ethoxyethanol (2-EtO-EtOH) with hexylamine (HLA), diethylamine (DEA), triethylamine (TEA), tert-butylamine (TBA), aniline (ANL), and benzylamine (BLA) have been determined at varying compositions of the alkoxyalkanols at 298.15 K. The excess molar volumes, VE, of the binary mixtures were calculated from the experimental density data of the mixtures and the component single solvents. The calculated excess molar volumes were fitted into the Redlich-Kister polynomial to obtain the fitting coefficients and standard deviations. The excess molar volumes of the binary mixtures of all the solvent systems investigated were negative over the entire range of the solvents composition. The negative values were attributed to stronger hydrogen bond formations between the unlike molecules of mixtures than those between the like molecules of the pure components. The magnitude of the excess molar volumes of the binary mixtures of 2-methoxyethanol and the aliphatic amines were in the order TBA > TEA > DEA > HEA. For the two aromatic amines, the magnitudes were in the order BLA > ANL. For binary mixtures of the amines and 2-ethoxyethanol, the magnitudes were in the order DEA > TEA > TBA > HEA at compositions where the mole fraction of 2-EtO-EtOH was ≤0.5 and TBA > TEA > DEA > HEA above 0.5 mole fraction of 2-EtO-EtOH.
