✦ Synopsis

This article critically reconsiders a continuous linear association model based on the work of Flory and Scatchard. The model is used to reduce experimental equilibrium data for solutions of alcohols and saturated hydrocarbons;

special attention is given to recent extensive enthalpy data of Van Ness which cover a broad range of composition and temperature. The model gives an excellent representation of the experimental results for solutions concentrated in alcohol. However, for dilute solutions, or for high temperatures, where the degree of association is small, the assumptions used by Flory do not apply and the model fails.
