ASSOCIATION MODEL OF FLUIDS - PHASE-EQUILIBRIA AND EXCESS-ENTHALPIES IN MIXTURES CONTAINING ALCOHOL AND ACETONITRILE

The binary vapor-liquid, liquid-liquid equilibria and excess molar ent halpies of mixtures including alcohol and acetonitrile are correlated well with a new association model whose equilibrium constants are defi ned in terms of the modified segment fractions of chemical species. Th e model shows a good performance in predicting the ternary phase equil ibria and excess molar enthalpies for mixtures containing alcohol, ace tonitrile, and benzene or chlorobenzene or toluene from only binary pa rameters.
