Density (rho), viscosity (eta), and ultrasonic velocity (U) have been measured for binary mixtures of methyl formate with 1-butanol, 1-pentanol and 1-hexanol at 303 K. From the experimental results, adiabatic compressibility (beta), acoustic impedance (Z), viscous relaxation time (tau), free length (L (f)), free volume (V (f)), internal pressure (pi(i)), and Gibbs free energy (Delta G) have been determined. Excess values of various parameters have also been calculated and interoperated in terms of molecular interactions. The deviations in the parameters show that strength of intermolecular interactions between methyl formate with selected 1-alcohols have been observed in the order of 1-butanol < 1-pentanol < 1-hexanol.
