Densities of 2,2,2-trifluoroethanol in the temperature range from 310 K to 420 K II. Compressed-liquid densities at pressures up to 200 MPa

Density measurements at given temperatures and pressures in the compressed liquid phase for 2,2,2-trifluoroethanol were carried out with a metal-bellows variable volumometer. The results cover the high-density region from 1111 kg·m −3 to 1553 kg·m −3 along 15 isotherms between 310 K and 420 K at pressures from 0.1 MPa to 200 MPa. The experimental uncertainties of temperature T , pressure p , and density ρ , were estimated to be ≯ |3 mK|, |0.0010· p |, and |0.0010· ρ |, respectively. On the basis of the present results, the isothermal compressibility and the isobaric expansivity were calculated.
