Description 409-412
Densities, viscosities, refractive indices of binary liquid mixtures composed of methyl formate and o-, m- and p-xylenes were determined at 303.15K and atmospheric pressure for the whole range of composition. From the experimental results the deviation in viscosity (Δη), excess Gibbs free energy of activation of flow (ΔG*E), and the deviation in molar refraction (ΔR) were deduced. The deviation in viscosities were correlated with Redlich-Kister polynomial equation. The Δη values are negative while the values of ΔG*E are positive and the ΔR values are both positive and negative over the entire range of composition for all the studied systems. The ability of different one parameter and two parameter empirical models to pre-dict mixing viscosities was also studied.
