Measurement of densities ( ρ ), viscosities (η) and ultrasonic speeds of sound ( u ) has been carried out for binary mixtures of acetophenone with butylamine, cyclohexylamine, dipropylamine, and dibutylamine at T = (303.15, 308.15 and 313.15) K. The experimental data have been used to calculate the excess molar volumes (VE), deviation in viscosity (Δη,), isentropic compressibility (Ks), deviation in speeds of sound (∆u) and deviation in isentropic compressibilities (∆Ks). These excess properties were correlated with Redlich-kister polynomial equation. Further the predictive ability of some selected viscosity models (Tamura-Kurata, Heric, McAllister (4-body)) was tested. The Speeds of sound data were also correlated using Vandel- Vangeel, and Jouyban- Acree models. The results were interpreted in terms of inter molecular interactions.
