In the present study acoustic impedance (Z) was computed for weakly interacting liquid mixture of 1-butanol and dodecane over the entire concentration range and atmospheric pressure from 288.15-318.15K. Flory’s statistical liquid state model based on non-association process and models based on association process such as Ramaswamy- Anbananthan (RS) and Gilinsky have been applied for the computation of aforesaid acoustical parameters and compared with the experimental work of J. Peleterio. McAllister multibody interaction model based on Eyring’s theory of absolute reaction rate was used to correlate the experimental results in terms in terms of numerical coefficients and standard deviation. Theoretical results calculated from association process deals a good agreement with experimental results in comparison to non-association process.
