摘要：

Density (rho), viscosity (eta) and ultrasonic velocity (U) have been measured for a ternary mixture composed of ethyl formate, 1-propanol and benzene have been determined at 303 K. The adiabatic compressibility (beta), free length (L (f)), free volume (V (f)) and internal pressure (pi(i)) have been calculated. The excess values of adiabatic compressibility (beta(E)), excess free length (L (f) (E) ), free volume (V (f) (E) ) and internal pressure (pi (i) (E) ) have also been computed by using the experimental data at 303 K. The deviation in the excess values reveal that intermolecular interactions obtaining in the solution.
