DYNAMIC VISCOSITIES OF (METHYL ACETATE OR METHANOL) WITH (ETHANOL, 1-PROPANOL, 2-PROPANOL, 1-BUTANOL, AND 2-BUTANOL) AT 298.15K

Viscosities have been measured for the binary mixtures methyl acetate + (methanol, or ethanol, or L-propanol, or 2-propanol, or l-butanol an d 2-butanol), and methanol + (ethanol, or l-propanol, or 2-propanol, o r l-butanol and 2-butanol) and their viscosity deviations were evaluat ed at 298.15 K and atmospheric pressure over the entire composition ra nge. Several semiempirical relations have been proposed to estimate dy namic viscosity, and the results were compared with the experimental d ata. The UNIFAC-VISCO group contribution method, Lobe's volume fractio n exponential model, and the group contribution thermodynamics viscosi ty model (GC-UNIMOD) have been used to predict the dynamic viscosity.
