The equation of state derived in a previous publication[ll is used to correlate vapour-liquid, liquidliquid, and gas-gas equilibria in biiy mixtures. Special mixiig rules for the parameters of the equation of state are derived from a quasichemical lattice model. It is possible to describe phase equi

✦ Synopsis
Abhwt
-A semiempirical equation of state has been developed for non-polar and weakly polar fluid substances from the square well model of the inter-molecular pair potential. The equation of state has three adjustable parameters and contains corrections for non-spherical molecular shape, "soft" repulsion potential, and three-body effects.

We have employed a theoretical equation of state for the calculation of the properties of real quadrupolar fluids whose interactions can be represented by a square-well with an embedded point quadrupole. This equation has only four disposable parameters: depth, range, diameter, and quadrupole moment
