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