An isomorphic generalization of the law of corresponding states for binary mixtures

Abstract

An isomorphic equation of state for binary mixtures has been obtained on the basis of an asymmetric scaled equation for one-component liquids. To extend this equation to the whole range of concentrations a new isomorphic generalization of corresponding states was introduced. The resulting equation has been applied to methane-ethane mixtures and describes experimental P,V,T,X data in a wide region above the critical line. Good agreement with experimental data is observed.
