Binary mixtures of 2-ethyl-1-hexanol with various functional groups (benzyl chloride, 3-methylaniline, 3-methoxyaniline and 2,6-dimethylcyclohexanone)

In the binary mixtures of 2-ethyl-1-hexanol with various functional groups (benzyl chloride, 3-methyl aniline, 3-methoxy aniline and 2,6-dimethyl cyclohexanone) densities, speeds of sound and viscosities including those of pure liquids were measured over the entire composition range at different temperatures (303.15, 308.15 and 313.15) K and atmospheric pressure 0.1 MPa. Using this experimentally determined data, the excess/deviation parameters (molar volume, isentropic compressibility and deviation in viscosity) partial molar volumes, partial molar isentropic compressibilities of these components at infinite dilution were calculated. The results are discussed in terms of intermolecular forces between different component molecules in the binary mixture are more than the average intermolecular forces existing between the similar molecules of pure components.
