Several equations for predicting vapor-liquid equilibria from the physical properties of the components have been proposed in the literature. Two equations of this type proposed by O. Redlich and others have been investigated to determine their utility.

Results indicate the two equations give fairly satisfactory results for nearly ideal solutions, but are unsatisfactory for non-ideal solutions. Knowledge of molecular interactions in the solution would be necessary before the predictions could be used with confidence.
