This article presents densities, ρ, and speeds of sound, u, of 1-butoxy-2-propanol CH 3 (CH 2 ) 3 OCH 2 CH(OH)CH 3 with alcohols, viz., 1-hexanol CH 3 (CH 2 ) 5 OH, 1-octanol CH 3 (CH 2 ) 7 OH, and 1-decanol CH 3 (CH 2 ) 9 OH at 293. 15, 298.15, 303.15, 308.15, and 313.15 K over the entire composition range. These experimental data of density and speed of sound were used to calculate the values of excess molar volumes, V m E , excess molar isentropic compression, κ S,m E , and deviation in speeds of sound, μ D . The calculated excess properties are discussed in terms of molecular interaction between present investigated binary mixtures and with Fourier transform infrared spectroscopy. These excess functions and their deviations in sound velocity have also been correlated using Redlich−Kister type polynomial equation by the method of least-squares for the estimation of the binary coefficients and the standard errors. The calculated properties were interpreted in terms of molecular interactions and structural effects.
