The density and viscosity of binary and ternary mixtures of 2,5 Hexandione with cyclopentanol and cyclohexanol were measured at 298.15, 303.15, 308.15 and 313.15 K, from using this data (density and viscosity) the excess molar volume VE, Viscosition deviation ∆ɳ and activation excess parameters ∆G*E, ∆H*E and ∆S*E have been calculated. The results were fitted by Redlich-Kister equations. Negative and positive deviations are obtained for both the binary and ternary Systems at temperatures under study. This expose that the presence of intermolecular interactions in the binary and ternary mixtures.
