Physical properties of the ternary system 1-butanol plus methanol plus 2-methoxy-2-methylpropane at 298.15 K: Measurement and prediction

Densities, refractive indices, speeds of sound, excess molar volumes (V-E), and deviations in molar refractions (Delta R) and isentropic compressibili ties (Delta kappa(s)) were determined for the system 1-butanol + methanol 2-methoxy-2-methylpropane at 298.15 K and atmospheric pressure. The values of V-E, Delta R, and Delta kappa(s) were satisfactorily correlated by the Redlich-Kister polynomial. These values were also predicted using several e mpirical equations from the values of their constituent binary subsystems, and the best results were obtained with the Kohler and the Radojkovic equat ions.
