The thermodynamics of alcohols-hydrocarbons mixtures

Abstract

The thermodynamic properties of alcohol‐hydrocarbon mixtures are explained on the basis of association of the alcohol to form polymers of all orders from two to infinity. Our treatment differs from that of Redlich and Kister in using the Flory‐Huggins expression for free energy, and an equilibrium constant in terms of concentrations rather than mole fractions. The equations derived are in satisfactory agreement with vapor‐pressure data for several systems. They also agree with the experimental energy of mixing and excess entropy for ethanol‐methylcyclohexane solutions. For mixtures of alcohols with aromatic hydrocarbons, it is necessary to assume that each alcohol monomer or polymer can combine with one molecule of hydrocarbon.
