The thermophysical parameters, viz. excess molar volume (VE), viscosity (η), speed of sound (u) and spectroscopic parameter (FTIR) have been measured for binary mixtures of 3-chloroaniline with isomeric butanols (1-butanol, 2-butanol and 2-methyl-2-propanol) over the entire range of mole fraction at 303.15, 308.15, 313.15K and 318.15K. The excess isentropic compressibility, deviation in excess viscosity and excess Gibbs energy of activation of viscous flow have also been estimated and analyzed. The spectroscopic measurement confirms that the interaction between unlike molecules takes place through hydroxyl groups of isomeric butanols. A good agreement is obtained between excess quantities and spectroscopic data. •VE, κsE and Δη were calculated using the experimental data.•VE, κsE, and Δη were fitted to the Redlich–Kister equation.•Hydrogen bonding interaction between 3-chloroaniline and organic solvent is supported by the FTIR spectra.•The experimental temperature ranges from 303.15.15 to 318.15K.
