✦ Synopsis

An associated soIut~on theory based on the UNIQUAC equation IS developed to descnbe the excess propeties of the alcohols m unassociated active components The theory mcludes two association constants the one for the alcohots, the other for alcohol-unassociated active component complexes The theory reproduces well the activity coefficients of the ethanol-tnchloromethane system havmg a maxunum and a mnnmum and rt also fits very skewed excess enthalpy curves for alcohol-benzene, alcohol-tetrachloromethane, etc Prediction of ternary vapor-hquld and hqmd-hqmd eqmhbrmm and excess enthalpy data has been carried out with good accuracy from bmary parameters w&out addmg any ternary constant
