Abstract
The FHN equation of state proposed in a previous paper has also been applied to mixtures of n-alkanes. The values of excess enthalpy, volume, and chemical potential obtained from the FHN equation using the reduction parameters independent of temperature were somewhat different from those derived from the Flory theory which uses reduction parameters dependent on temperature. The interaction parameters χ and excess volumes VE calculated from six equations of state including the FHN equation, were compared with each another for solutions of poly(dimethylsiloxane) in various solvents, under the assumption that the combining rule for mixing given by Flory is valid. No equations gave agreement between the observed and calculated values of χ and VE.
