abstract
This paper reports densities of compressed R134a (1,1,1,2-tetrafluoroethane) determined by using a contiuously weighed pycnometer at 20 K intervals between 180 and 380 K at pressures from slightly greater than the vapour pressure to 70 MPa. The results are accurate to within 0.1%. Saturated liquid densities derived by extrapolation from the experimental values agree with other reported values to within 0.3%. 1992.
