개요
Cobalt(II) iodide is a iodide of cobalt. It is used to detect the presence of water. Cobalt is a metallic element with the atomic number 27. It is found naturally in rocks, soil, water, plants, and animals. In small amounts cobalt is an essential element for life, as it is part of vitamin B12. However, excess exposure is known to exhibit toxic effects. (L29, L30, L33)

Metabolism/Metabolites
Cobalt is absorbed though the lungs, gastrointestinal tract, and skin. Since it is a component of the vitamin B12 (cyanocobalamin), it is distributed to most tissues of the body. It is transported in the blood, often bound to albumin, with the highest levels being found in the liver and kidney. Cobalt is excreted mainly in the urine and faeces. (L29)

General Manufacturing InformationCobalt iodide (CoI2): ACTIVE
응용 분야
개요Cobalt iodide appears as black crystals with a slight ‘iodine’-like odour. When heated to decomposition, it may emit toxic fumes of iodine and oxides of nitrogen. Anhydrous cobalt (II) iodide is sometimes used to test for the presence of water in various solvents. Cobalt (II) iodide is used as a catalyst, for example, in carbonylations. It catalyses the reaction of diketene with Grignard reagents, useful for the synthesis of terpenoids.
용도Cobalt(II) iodide is used as a moisture and humidity indicator. It is also used as a catalyst.
제조 방법
Cobalt(II) iodide is prepared by heating cobalt powder in a stream of hydrogen iodide at 400 to 450°C: Co + 2HI → CoI2 + H2 The product obtained is the black crystalline α-form. Cobalt(II) iodide also may be made by heating cobalt powder with iodine vapor.
