This paper reports densities (rho) and speeds of sound (u) of 2-butoxy ethanol CH3(CH2)(3)OC2H4OH, 1-propanol CH3(CH2)(2)OH, 2-propanol (CH3)(2)CHOH, 1-butanol CH3(CH2)(3)OH and 2-butanol CH3CH2CH(OH)CH3 and their binary mixtures with 2-butoxy ethanol as a common component, measured at 293.15, 298.15, 303.15, 308.15 and 313.15 K and viscosities (eta) measured at 298.15, 303.15 and 308.15 K over the entire composition range. These experimental data were used to calculate the values of excess molar volume (V-m(E)), excess molar isentropic compressibility (K-s,m(E)), excess Gibbs free energy (Delta G*(E)) and deviation in speed of sound (u(D)) at all mole fractions of 2-butoxy ethanol. The observed variations of these properties, with composition and temperature, are discussed in terms of molecular interactions due to physical and chemical effects between the unlike molecules of the binary mixtures. These properties, especially excess functions, are found to be quite sensitive towards the intermolecular interactions in liquid mixtures. These excess functions and deviations 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. FT-IR and H-1 NMR studies of these mixtures are also reported. (C) 2013 Elsevier B.V. All rights reserved.
