EVALUATION OF EXCESS PARAMETERS FROM DENSITIES AND VISCOSITIES OF BINARY-MIXTURES OF ETHANOL WITH ANISOLE, N,N-DIMETHYLFORMAMIDE, CARBON-TETRACHLORIDE, AND ACETOPHENONE FROM 298.15 TO 313.15K

Densities and viscosities of four binary mixtures containing ethanol have been measured at 298.15, 303.15, 308.15, and 313.15 K over the entire mole fraction scale. These results are used to calculate excess molar volume and apparent values of excess viscosity and excess Gibbs energy of activation of flow. Efforts have also been made to compute the excess isobaric thermal expansivity of liquid mixtures by using the refractive index mixing rules. Such results when compared with experiments agreed reasonably well. © 1990, American Chemical Society. All rights reserved.
