Excess molar volume, excess isentropic compressibility, deviation in viscosity and excess Gibbs free energy for activation of viscous flow for binary mixtures of 4-hydroxy-4-methyl-2-pentanone e (DAA) with 1-butanol (B 1 ), 2-butanol(B 2 ) and 2-methyl-2-propanol(B 3 ) components selected compositions were determined from the measured values of densities ( ρ ), viscosities (), and speeds of sound ( u ) of pure components and their mixtures at from 303.15 K to 313.15 K. The results are analysed in terms of intermolecular interactions or hydrogen bonding or hetero-association interactions in the binary mixtures. Prigogine-Flory-Patterson (PFP) theory is applied to identify the predominant molecular interaction. Jouyban-Acree model results are discussed in terms of mean relative deviation (MRDs) and individual relative deviation (IRD) between calculated and experimental densities, speeds of sound and viscosities as an accuracy criterion
