ABSTRACT
This paper reports PVT data measured with a high-pressure, single-sinker, magnetic-suspension densimeter (MSD) from (298 to 450) K up to 200 MPa. The MSD technique yields accurate data, with less than 0.05 % relative uncertainty, over the pressure range of (10 to 200) MPa. The Bcker and Wagner equation of state as implemented in RefProp 8.0 compares well to the experimental data. RefProp 8.0 has a relative uncertainty of (0.02 to 0.03) % up to 30 MPa. The equation predicts data with almost the same uncertainty as the experimental data up to 200 MPa. These PVT data also allow reliable determination of both second and third virial coefficients.
