Gaseous pressure-volume-temperature properties of 1,1,1,2,3,3,3-heptafluoropropane
One-hundred and forty-one pressure-volume-temperature data points for 1,1,1,2,3,3-heptafluoropropane (HFC-227ea) in the gaseous phase have been measured using Burnett/isochoric methods. Burnett expansion measurements were made both at 363.15 K and 318.15 K. On the basis of the pressure-density relationships established at 363.15 K and 318.15 K, data were collected along nine isochores for temperatures from 283 to 377 K and pressures form 0.26 to 2.5 MPa. The maximum temperature uncertainty and maximum pressure uncertainty in this work were estimated to be within {plus{underscore}minus}10 mK and {plus{underscore}minus}500 Pa, respectively. On the basis of the present data and results from the literature, the parameters of a virial equation of state were determined to represent the gaseous thermodynamic properties of HFC-227ea. The purity of the sample used in this work is 99.9 mol %.
