The isobaric specific heat capacity of Refrigerant 13B1 (CBrF3) has been measured by the flow calorimeter. Thirty-four measurements were obtained in the gaseous region for temperatures 283 to 383 K up to 3 MPa including the region near the saturation line. The sample purity used was 99.99 wt%. The uncertainty of the measurements was estimated to be less than 1.3% and the reproducibility has been confirmed to be less than 0.7%. The present results reveal the bahavior of the isobaric specific heat capacity of R 13B1 in the gaseous region.
The present results were compared with the values calculated by the available equations of state. The comparison shows that no equation of state describes the present results with satisfactory accuracy.
