A study of the volumetric and phase behavior of binary systems. Part I. Critical properties of propane-perfluorocyclobutane mixtures

The volumetric and phase behavior of propane-perfluorocyclobutane mixtures has been determined in the critical region. This system exhibits a minimum temperature point in its critical locus curve and forms a positive critical azeotrope. The measured critical points in this system and their correlation using an extended corresponding states principle are reported in this paper.
