摘要：

The densities, refractive indexes, and sound velocities for mixtures of ethanol + methanol + dibutyl ether at 25 degrees C and atmospheric pressure, were determined and used to calculate molar volumes, molar refractions, and isentropic compressibilities. The excess molar volumes and the deviations of molar refractions and isentropic compressibilities from mole fraction and volume fraction averages, respectively, of these properties of the pure components were satisfactorily correlated with the composition data by means of the Redlich-Kister polynomial.
