Solid Vapor Pressure and Enthalpy of Sublimation for Ammonium Perfluorooctanoate

, 2016
A modified gas saturation method was used to directly determine the solid vapor pressure of ammonium perfluorooctanoate (APFO). Measurements were made over the temperature range from (45 to 60) °C. Pressures ranged from (0.04 ± 0.007) Pa to (0.17 ± 0.028)
