Solubility of Iodine in Sub/Supercritical Carbon Dioxide
The solubility of iodine in sub- and supercritical carbon dioxide was studied using a
flow-type extraction setup. It is shown that at 20—80 °C and 60—350 atm, the solubility
of iodine increases at rising temperature and CO2 pressure and the mole fraction of
iodine in its saturated solution ranges from 0,12 · 10-3 to 1,42 · 10-3.
