Abstract

Vapor-liquid equilibria were measured isothermally in the two title systems at 333.15, 343.15, and 353.15 K. A dynamic equilibrium still, allowing for the recirculation of both liquid and vapor phases was used. The data were correlated by means of the standard NRTL equation while considering the real behavior of the vapor phase, and with the use of the maximum likelihood procedure. Both the systems exhibited azeotropic behavior.
