The experimental values of density, viscosity, and ultrasonic velocity for the binary mixtures of cyclohexane + nitrobenzene, cyclohexanone + nitrobenzene, and cyclohexane + cyclohexanone are determined at (298.15, 303.15, and 308.15) K over the entire composition range. The excess molar volume (V-E), deviation in viscosity (Delta(eta)), and excess isentropic compressibility (K-S(E)) have been calculated.
