VAPOR-PRESSURE OF CHLORINE TRIFLUORIDE FROM 300 K TO 317 K

Vapor pressure of chlorine trifluoride was measured by a static-type a pparatus from 300 K to 317 K with corresponding pressures from 0.1848 MPa to 0.3349 MPa. The uncertainty of the measurement was less than +/ -0.03 K in temperature and +/-0.3 kPa in pressure. The purity of the s ample was more than 99.9999 mass %. The vapor pressure at 313.15 K was -0.2947 MPa. The experimental data were correlated by the Antoine and Frost-Kalkwarf equations. The correlated deviations of both equations were less than +/-0.05%.
