%X The experimental density (¦Ñ), viscosity (h) and velocity (U) have been measured for ternary mixtures of alcohols(1-propanol and 1-butanol) + acetonitrile + dimethylsulphoxide at different temperatures. These data were used to determine the excess molar volume, excess viscosity, excess relaxation time and excess acoustic impedance. The variation of these parameters with compostion of mixture indicates the nature and extent of interaction between unlike molecules. The non-ideal behaviour of the systems studied was explained on the basis of hydrogen bonding. Available thermal energy breaks the bonds between the associated molecules into their respective monomers on increasing the temperature.
