Isothermal vapor-liquid equilibria for the binary systems of chlorine with difluoromethane, chlorodifluoromethane, and dichlorodifluoromethane at 10 degrees C

摘要

Isothermal vapor-liquid equilibria for difluoromethane + chlorine, chlorodifluoromethane + chlorine, and dichlorodifluoromethane + chlorine have been measured. The experimental data are correlated with the Peng-Robinson equation of state, and the relevant parameters are presented. All of the binary systems form minimum boiling homogeneous azeotropes at the experimental conditions. The correlation of the vapor-liquid equilibria was found to be in good agreement with the experimental data. [References: 8]
