摘要：

An associated solution theory based on the UNIQUAC equation is developed to describe the excess properties of the alcohols in unassociated active components. The theory includes two association constants: the one for the alcohols, the other for alcohol-unassociated active component complexes. The theory reproduces well the activity coefficients of the ethanol-trichloromethane system having a maximum and a minimum and it also fits very skewed excess enthalpy curves for alcohol-benzene, alcohol-tetrachloromethane, etc. Prediction of ternary vapor-liquid and liquid-liquid equilibrium and excess enthalpy data has been carried out with good accuracy from binary parameters without adding any ternary constant. © 1979.
