The vapor pressure of CF, has been measured from 86-146K. The equation log ptorr 8.5019 - 769.89T represents the data for the solid. Above the triple point, 89.55K, the vapor pressure is represented by the equation, log ptorr 6.836841 - 511.69474T - 15.7744. The heat of vaporization calculated by the Clapeyron equation from the data ranges from 3.4 to 2.8 kcalmole from the triple point to the normal boiling point, 145.12K. Author
