The present paper reports the experimental data for density, rho, viscosity, eta, and speed of sound, u, for the binary mixtures of phenylacetonitrile (PAN) with aliphatic esters [ethyl acetate (EA), ethyl chloroacetate (ECA), and ethyl cyanoacetate (ECNA)] over the miscibility region (0 < x(1) < 1) at temperatures of (303.15, 308.15, and 313.15) K. The experimental data have been used to calculate various properties like the excess molar volume V(E) and deviation in isentropic compressibility Delta kappa(s). These properties are used to interpret the molecular interactions in the binary mixtures. The Redlich-Kister polynomial equation was fitted to the experimental data to derive binary coefficients and standard deviations.
