Abstract
A new temperature-dependence is proposed for the depth of the square-w ell parameter in the Christoforakos-Franck equation of state. A compar ison of theory with experiment is reported for the vapour-liquid equil ibria of 30 one-component fluids including the noble gases, alkanes, c yclic hydrocarbons, ketones, alkanols and chlorocarbons, which indicat es that the modified equation can be accurately employed at sub-critic al conditions. The results are also compared with available data for t he simplified perturbed hard-chain theory equation of state.
