Abstract

Based on a quasilattice model of a multicomponent soln., 3 equations are derived relating component activity coeffs. to the compn. of a liq. mixt. The equations also apply to systems showing limited miscibility. Temp. dependence of activity coeffs. is built in. The equations were tested for 16 binary systems, 5 of which show limited miscibility, and for 4 ternary systems. The enthalpic Wilson equation, one of the 3, gives the best prediction of binary vapor-liq. equil. Both the enthalpic Wilson equation and the Orye equations give good results of comparable accuracy for the ternary systems. [on SciFinder (R)]
