Densities, refractive indices, speeds of sound, and isentropic compressibilities of water plus methanol plus 2-methoxy-2-methylbutane at 298.15 K

The densities, refractive indices, and speeds of sound of homogeneous mixtures of water + methanol + 2-methoxy-2-methylbutane at 298.15 K were determined and used to calculate excess molar volumes (V-E), molar refractions (R), and isentropic compressibilities (k(s)). The V-E data and the deviations of R(Delta R) and k(s)(Delta h(s)) from mole fraction and volume fraction averages, respectively, of these properties of the pure components, were satisfactorily correlated with the composition data using the Redlich-Kister polynomial.
