- Density of HCFC 142b and of its mixture with HCFC 22Publication . Sousa, Ana T.; Fialho, Paulo; Nieto de Castro, Carlos A.; Tufeu, R.; Le Neindre, B.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.
