Density of HCFC 142b and of its mixture with HCFC 22. "Fluid Phase Equilibria", 80: 213-225.0378-3812http://hdl.handle.net/10400.3/1284Copyright © 1992 Published by Elsevier B.V.The density of the binary mixture 40/60 wt% of monochlorodifluoromethane (HCFC 22) and 1-chloro-1,1-difluoroethane (HCFC 142b) in the liquid phase, has been measured between 300 and 370 K and pressures up to 19 MPa, with an oscillating fork sendimeter, operating in a relative mode. Toluene and vacuum have been used as calibrating fluids. The accuracy of the data is 0.08 %. An equation for the dependence of density in temperature and pressure for HCFC 142b and for this mixture is also presented.engBinary MixtureDensityDensimeterMonochloro-difluoromethane1-chloro-1,1-difluoroethaneEquation of StateLiquidjournal article
