Thermodynamic properties of 1,1-dichloro-1-fluoroethane (R141b) were m
easured using a vibrating-tube densimeter and two different ebulliomet
ric techniques. The densimeter was used to measure compressed liquid d
ensities, and the ebulliometers were used to study the vapor pressure.
Measurements of the density were made between 278 and 369 K and betwe
en 100 and 6000 kPa. The vapor pressure was measured from 253 to 355 K
at pressures from 10 to 449 kPa. Both the compressed liquid and the v
apor pressure results are compared with other published data. Our resu
lts for the vapor pressure have been combined with results already pub
lished to obtain a correlation for the vapor pressure from 253 K to th
e critical point.
