Isothermal Vapor−Liquid Equilibria for the Binary Systems of Chlorine with Difluoromethane, Chlorodifluoromethane, and DiChlorodifluoromethane at 10 °C
Journal of Chemical & Engineering Data, 1998Co-Authors: Yun Whan KangAbstract: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.

Journal of Chemical & Engineering Data, 1996Co-Authors: Yun Whan Kang, Kun Yong ChungAbstract:Isothermal vapor−liquid equilibria for the three binary systems (difluoromethane + Chlorodifluoromethane, difluoromethane + diChlorodifluoromethane, and difluoromethane + chloromethane) have been measured at 10.0 °C. The experimental data for the binary systems are correlated with the Wilson equation and the relevant parameters are presented. The difluoromethane + diChlorodifluoromethane system forms a minimum boiling azeotrope, but the others do not.

Bubble point pressures for Chlorodifluoromethane + 1,2-dichloro-1,1,2,2-tetrafluoroethane, bromotrifluoromethane + 1,2-dichloro-1,1,2,2-tetrafluoroethane, and bromotrifluoromethane + chloropentafluoroethane
Journal of Chemical & Engineering Data, 1993Co-Authors: Kenji Mishima, Masaru Hongo, Toshiharu Takagi, Yasuhiko AraiAbstract:The bubble point pressures for Chlorodifluoromethane (R22) + 1,2-dichloro-1,1,2,2-tetrafluoroethane (R114), bromotrifluoromethane (R13B1) + 1,2-dichloro-1,1,2,2-tetrafluoroethane (R114), and bromotrifluoromethane (R13B1) + chloropentafluoroethane (R115) were measured by a static method. Measurements were made at various compositions at temperatures from 298.15 K to near their critical temperature. The uncertainty of the pressures was estimated to be no greater than [plus minus]0.3%. The bubble point pressures for pure substances were correlated by the Wagner equation, and those for the mixtures were also correlated by the Wagner equation, using a corresponding states principle.

adsorption of diChlorodifluoromethane Chlorodifluoromethane chloropentafluoroethane 1 1 difluoroethane and 1 1 1 2 tetrafluoroethane on silica gel
Journal of Chemical & Engineering Data, 1994Co-Authors: Marc Frère, Karl Berlier, Jacques Bougard, Roger JadotAbstract:The CFC's (chlorofluorocarbons) are used as working refrigerants fluids. The most commonly used are R12, R22, and R502 (48.8% R22 and 51.2% R115). Recent concerns of the effects of CFC's on the ozone layer require the development of efficient recovery methods. One technique is to adsorb the fluids onto a porous medium such as silica gel. Thermodynamic data on the adsorption of diChlorodifluoromethane (R12), Chlorodifluoromethane (R22), chloropentafluoroethane (R115), 1,1-difluoroethane (R152a), and 1,1,1,2-tetrafluoroethane (R134a) on silica gel are required for the design of recovery units. The results are presented here.

clathrate phase equilibria for the water deuterium oxide carbon dioxide and water deuterium oxide Chlorodifluoromethane r22 systems
Journal of Chemical & Engineering Data, 1996Co-Authors: Moonkyoon Chun, Ji Ho YoonAbstract:Clathrate phase equilibria for two ternary water + deuterium oxide + carbon dioxide and water + deuterium oxide + Chlorodifluoromethane (R22) systems were measured at several different mass % of water and deuterium oxide mixtures. Equilibrium dissociation pressures of these two ternary systems at the three-phase (clathrate−liquid−vapor) boundaries range (1.43 to 4.86) MPa and (0.141 to 0.886) MPa, respectively. The temperature range occupied by the three-phase boundary of the water + deuterium oxide + R22 system is a little larger than that of the water + deuterium oxide + carbon dioxide system. The dissociation pressures at the quadruple points were found to steadily increase with deuterium oxide composition.
