Abstract
Density, refractive index on mixing, and speed of sound at 293.15 K, 298.15 K, 303.15 K, and 313.15 K and atmospheric pressure have been measured over the whole composition range for dimethyl carbonate (DMC) + methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and 1-pentanol. Excess molar volumes, changes of refractive index on mixing, and deviations in isentropic compressibility for the above systems have been calculated. The Redlich−Kister equation has been used to estimate the binary fitting parameters, and root-mean-square deviations from the regression lines are shown. The excess molar volumes were fitted as a function of the mole fraction and temperature to a polynomial equation.
