Abstract

The method determining pure substance constant for three-parameter cubic equation of state has been presented. The analytical correlations for calculating pseudocritical mixture parameters obtained on the basis of the critical conditions for pure substance have been given. The fitting parameter for the equation of state dependence on the compressibility coefficient and acentric factor at the critical point has been analyzed.
