Viscosity, second pVT virial coefficient, and diffusion of binary mixtures of small alkanes CH4, C2H6, C3H8, n-C4H10, i-C4H10, n-C5H12, i-C5H2, and C(CH3)(4) predicted by means of an isotropic temperature-dependent potential
The isotropic (n-6) Lennard-Jones temperature-dependent potential (LJTDP) together with the Hohm-Zarkova-Damyanova mixing rules is used to predict second interaction pVT virial coefficients B-AB(T), interaction viscosities eta(AB)(T), and diffusion coefficients D-AB(T) for all 28 binary mixtures of the alkanes CH4, C2H6, C3H8, n-C4H10, i-C4H10, n-C5H12, i-C5H12 and C(CH3)(4) at low densities. Where possible, the obtained equilibrium and transport data are compared to existing measurements. In general, good agreement is found between experiment and theory. On the basis of these findings, fitting formulas and tables are presented which allow for a fast and reliable estimation of the aforementioned properties in the temperature range between (180 and 1200) K.
