ABSTRACT

Dynamic viscosities, exp for the binary mixtures of methanol with isomeric (o-, m-, and p- derivatives) xylenes were measured at T = (303.15, 308.15, 313.15, 318.15, and 323.15) K and atmospheric pressure. The viscosity deviation, that has been derived from the exp was correlated using a Redlich-Kister type equation. The exp values were compared with the calculated viscosities, cal obtained using generalized correlation models, such as Bingham, Arrhenius, Kendall-Monroe, Grunberg-Nissan, and Andrade/DIPPR. The changes in the exp of solvent mixtures than the pure fluids, or deviations from the cal have been discussed in terms of the molecular interactions and structural effects due to the component molecules. Furthermore, the quantum chemical density-functional theory calculations were used to predict the optimized geometry and total energies of the pure fluids and their binary mixtures.
