Abstract

A correlation of salt effect on vapour‐liquid equilibria for nonaqueous binary system is presented. The correlation is applicable to systems in which the salt is dissolved in only one of the volatile components. Assumptions are made to obtain a correlation on the basis of a simplified mechanism of salt effect. The main feature of this correlation is that it does not require an experimental parameter for the salt effect. The applicability of this method is examined by using new experimental salt effect data on benzene‐ethanol azeotropic mixture for the addition of lithium chloride, calcium chloride and zinc chloride. It was found from the examinations that the prediction of the vapour phase composition was successful.
