Molecular interactions in binary mixtures of ethyl benzoate + ethers at (303.15, 308.15 and 313.15) K

The density, viscosity and speed of sound at temperatures (303.15, 308.15 and 313.15) K were measured for the binary mixtures of ethyl benzoate with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether over the entire range of mixture composition. From these data excess volume, VE, isentropic compressibility, Ks, intermolecular free length, Lf, internal pressure, πi and free volume, Vf, have been calculated. The computed excess quantities were fitted to the Redlich-Kister equation. This work also provides a test of Katti and Chaudhri and McAllister's (3-body and 4-body) equations for correlating the viscosities of the binary mixtures.
