Abstract

Vapor-liquid equilibrium calculations often ignore the nonideal behavior of the vapor phase. In this paper, the justification of neglect is investigated on measured P-v-T data of pure organic solvents and their binary mixtures, and on published data. Except for systems containing components strongly associating in the vapor phase, vapor correction was found to be essential only for activity coefficient values in the liquid phase close to unity, and for polar molecules. P-v-T data were determined in a Boyle's apparatus. Mathematical statistical methods are used to establish and develop the test method and to evaluate the results.
