Property changes of mixing for the 1-butanol plus methanol plus 2-methoxy-2-methylbutane system at 298.15 K and atmospheric pressure

Densities, refractive indices, and speeds of sound at 298.15 K and atmosphe ric pressure for the l-butanol + methanol + 2-methoxy-2-methylbutane ternar y system have been measured. Excess molar volumes, molar refraction, and is entropic compressibility changes of mixing were determined from experimenta l measurements. The results were fitted to the Redlich-Kister equation to o btain the coefficients. These property changes were also predicted using se veral empirical equations from the values of their constituent binary subsy stems, and the best results were obtained with the Kohler equation.
