Abstract
A process for preparation of crystal iodine with minimal content of organic admixtures from iodine-raw product, wherein iodine sublimation is carried out in two stages: on the first stage iodine is sublimated in the flow of atmosphere air in the presence of sulphuric or orthophosphoric acid, on the second stage the obtained iodine is sublimated in the flow of atmosphere air in the presence of water and alkali reagent (sodium carbonate, sodium bicarbonate or sodium hydroxide).
