Experimental P-T-p and enthalpy-increment measurements of trichlorofluoromethane, R-11 (x=0.83), plus chlorodifluoromethane, R-22 (1-x) Academic Article

abstract

• We have measured experimental liquid densities for R-11 (x = 0.83 nominal) + R-22 (1 - x) using a continuously weighed pycnometer (for liquid densities) and a semi automated, isochoric apparatus (for measurements in the vapor and liquid regions). We calculate phase boundaries from the isochoric measurements, A thermoelectric flow calorimeter was used to measure enthalpy differences in the vapor and liquid regions. The temperature range for all measurements is (230 to 425) K. The experimental pressures range up to 69 MPa for the pycnometer, 9 MPa for the isochoric apparatus, and 6.5 MPa for the calorimeter.
