Abstract
The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results were discussed in terms of intermolecular interactions and structure of studied binary mixtures. Free-volume theory coupled with the Peng–Robinson–Stryjek–Vera equation of state has been applied for calculation of viscosities of pure compounds and the binary liquid mixtures. The Agreement between experimental data and theoretical values was satisfactory.
