ABSTRACT

Viscosities have been determined for the binary mixtures dimethyl carbonate (DMC) + hexane, + heptane, + octane, and + cyclohexane and diethyl carbonate (DEC) + hexane, + heptane, + octane, and + cyclohexane at (293.15, 298.15, 303.15, and 313.15) K and atmospheric pressure. Viscosity deviations for the binary systems were fitted to the Redlich-Kister equation. From these experimental data, the interaction parameters (CH3-OCOO), (CH2-OCOO), and (CH2cy-OCOO) have been determined for their application in the UNIFAC-VISCO method, based on contribution groups, to predict the dynamic viscosities of the binary mixtures. Root-mean-square deviations are also gathered.
