Acoustic Data on Molecular Interactions in Mixtures of Nitromethane and Nitroethane in Acetone at 303–318 K

Resumo

Densities and ultrasonic velocities of binary mixtures of (nitromethane + acetone) and (acetone + nitroethane) in the volumes fraction range 0.1–1 at 298–318 K were measured. The obtained data were used to compute adiabatic compressibility, intermolecular free length, acoustic impedance, molar volume, molar sound velocity, molar compressibility, relative association, excess volume, and excess adiabatic compressibility. The results were discussed in terms of the existence of dipole–dipole and dipole induced molecular interactions between the compounds in the liquid mixture under study. A comparative study has been established between two liquid mixtures under investigation.
