Thermodynamics of molecular interactions between nitromethane and aromatic hydrocarbons

Abstract

Excess volumes of mixing VE, excess enthalpies HE, and excess Gibbs free energies of mixing GE, of binary mixtures of nitromethane with aromatic hydrocarbons have been measured at 303.15 and 313.15 K. The VE, HE, and GE data, which are positive throughout the entire range of concentrations, have been examined with Winnick's theory. The calculated VE, HE, and GE values compare reasonably well with the corresponding experimental values. The theory also correctly predicts the influence of temperature on these excess functions.
