colorless or light yellow hexagonal crystal or powder, bitter taste. Melting point 740 °c I Boiling point 1100 °c. It has deliquescence. Absorption of carbon dioxide in the air, the decomposition of free iodine and yellow. Soluble in water, aqueous solution is neutral, soluble in methanol, ether, acetone, soluble in acid that is decomposed, free iodine or hydroiodic acid.
Iodine reacts with iron filings to generate ferrous iodide, and then interacts with calcium hydroxide to generate calcium iodide, which is obtained by separation, filtration, concentration, decolorization and evaporation and crystallization. Alternatively, hydrogen iodide is obtained by the action of hydrogen sulfide and iodine, and hydrogen iodide is reacted with calcium hydroxide or calcium carbonate to obtain a calcium iodide solution. The solution may be concentrated by heating and cooled to crystallize.
It is used as a substitute for potassium iodide in the field of medicine, and can also be used as a photographic emulsifier, a fire extinguishing agent, a desiccant for hydrogen iodide, and an analytical reagent.
