ABSTRACT

Critical parameters and vapor pressures of five possible replacement compounds for chlorofluorocarbonssfour hydrofluoroketones and a hydrofluoroamineswere measured with an accuracy of +/- 10 mK, 0.5 kPa, and 1 kg.m-3. Critical temperatures, pressures, and densities were in the ranges from 450 to 500 K, from 2.3 to 3 MPa, and from 450 to 550 kg.m-3, respectively. Among the five compounds examined, one of the hydrofluoroketones, HFK-354pc (CHF2CF2C(=O)CH3), was relatively unstable.
