an experimental study of the thermodynamic properties of different binary mixtures

Interactions between binary mixtures of isobutanol + cyclohexylamine and 2-methylcyclohexanol and aniline were investigated by thermodynamic properties. the densities of the binary mixtures were measured for different mole fractions at temperatures of 293.15, 298.15, 303.15, 308.15 and 313.15 k and atmospheric pressures by experimental. excess molar volumes were calculated from this data. excess molar volumes have been negative due to the deviation from the ideal state of the mixtures.
