| Abstract: | Molecular interaction, adiabatic compressibility, intermolecular free length, molar volume, available volume and free volume have been computed by measuring ultrasonic velocity and density at 23°C in three ternary liquid mixtures with p-xylene as common component. The systems are I p-xylene-acetone-carbon tetrachloride, II p-xylene-acetone-cyclohexane and III p-xylene-benzene-cyclohexane. Molecular interaction is maximum when the mole fraction of acetone is 0.5 in I and 0.6 in II. It remains almost constant in III indicating no interaction in this case. The excess properties have also been given and the interactions explained. |
