Experimental vapor pressure data and a vapor pressure equation for trifluoroiodomethane (CF3I)

Sixty four vapor pressure data points for trifluoroiodomethane (CF3I) have been measured for the temperature range from 243.15 to 393.15 K. The maximum total pressure uncertainty of these data is estimated to be within ± 1.0 kPa. The purity of the sample used in this work is 99.95% with 3.4 ppm of water. Based on this data set, a vapor pressure equation for CF3I has been developed. This equation contains four coefficients and correlates the measured vapor pressures within ± 0.03%.
