Abstract

The densities were measured over the entire molefraction range for the binary liquid mixtures of Cyclohexanol with 2-Nitrotoluene & 3- Nitrotoluene at four different temperatures (303.15 K, 308.15 K, 313.15 K, 318.15 K). From the experimental data, excess molar volumes ( E ) m V values were calculated. These values are negative for Cyclohexanol + 2-Nitrotoluene and positive for Cyclohexanol + 3-Nitrotoluene. The excess molar volumes ( E ) m V values are analysed on the basis of molecular interactions between unlike non-electrolyte molecules.
