Generally, excess properties in binary liquid mixtures exhibit positive or and/or negative deviation and tend to zero at infinite dilution (pure component). The expression is written in generally as : Yex = x1.x2.polynomial on (x1-x2) which can be re-expressed as: Yex = x1.x2.Qy,exp where Qy,exp is the experimental Reduced Redlich-Kister excess property which can be plotted using the relationship : Qy,exp = Yex / x1.x2.
Nevertheless, when we plot the mathematical product Pix = +/- x1.x2, we obtain similar curves to those of Yex property (zero at infinite dilution, etc...).
Can we conclude that the observed deviation of Yex is due principally to the mathematical factor Pix and Qy,exp becomes an interesting specific indicator of molecular interactions of the studied binary mixture ?
