ABSTRACT

Densities, speeds of sound, and viscosities have been measured for the binary mixtures dimethyl carbonate + cyclopentane and diethyl carbonate + cyclopentane or methylcyclohexane at T = (293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric pressure. Excess molar volumes, viscosity deviations, and deviations in isentropic compressibility for the above systems have been derived. Derived quantities have been fit to a polynomial equation as a function of mole fraction and temperature. The obtained fitting parameters are listed. Correlated equations have been proposed, and the results in terms of root-meansquare deviations are shown. The UNIFAC-VISCO group contribution method has been used to predict the dynamic viscosities at the above temperatures for the binary mixtures.
