Changes of Refractive Indices for the Ternary Mixture Acetone + Methanol + N-Hexane at 288.15 and 298.15 K

Abstract

The refractive indices of the ternary mixture acetone + methanol + n-hexane have been measured at 288.15 and 298.15 K and atmosphere in the whole composition diagram. Parameters of polynomial equations which represent the composition dependence of physical and derived property are gathered. the use of a multicomponent extension of Heller equation in order to predict excess molar volumes from refractive indices on mixing are tested against literature data, a comparative accuracy with currently available models being obtained.
