ASSOCIATION MODEL OF FLUIDS - SIMULTANEOUS REPRESENTATION OF EXCESS GIBBS ENERGIES AND EXCESS-ENTHALPIES FOR LIQUID-MIXTURES WITH ALKANOLS

The binary excess Gibbs energies and excess enthalpies of liquid mixtu res of alkanols and hydrocarbons, acetone, methyl acetate, acetonitril e, organic acid, etc., are simultaneously correlated with a new associ ation model whose equilibrium constants are defined in terms of the mo dified segment fractions of chemical species. The model predicts terna ry vapor-liquid, liquid-liquid equilibria and excess molar enthalpies of those mixtures well using only binary parameters. (C) 1997 Elsevier Science B.V.
