概要

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)

毒性情報

TreatmentTreatment of cobalt poisoning is symptomatic. (L29)

Health EffectsExposure to high amount of cobalt can cause heart, lung, kidney, and liver damage. Skin contact is known to result in contact dermatitis. Cobalt may also have mutagenic and carcinogenic effects. (L29, L30)

Adverse EffectsSkin Sensitizer - An agent that can induce an allergic reaction in the skin.

Exposure RoutesInhalation (L29) ; oral (L29) ; dermal (L29)

Toxicity Summary · 1 件

Cobalt is believed to exhibit its toxicity through a oxidant-based and free radical-based processes. It produces oxygen radicals and may be oxidized to ionic cobalt, causing increased lipid peroxidation, DNA damage, and inducing certain enzymes that lead to cell apoptosis. Cobalt has also been shown to block inorganic calcium channels, possibly impairing neurotransmission. Cobalt can also chelate lipoic acids, impairing oxidation of pyruvate or fatty acids. In addition, cobalt may inhibit DNA repair by interacting with zinc finger DNA repair proteins, and has also been shown to inhibit heme synthesis and glucose metabolism. Cobalt may activate specific helper T-lymphocyte cells and interact directly with immunologic proteins, such as antibodies (IgA and IgE) or Fc receptors, resulting in immunosensitization. (L29)

Signs and SymptomsCobalt inhalation can cause asthma-like breathing problems. Skin contact is known to result in contact dermatitis, which is characterized by irritation and rashes. Ingesting large amounts of cobalt may cause nausea and vomiting. (L2090)

Metabolism/Metabolites · 1 件

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)

説明Cobalt 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.

使用Cobalt(II) iodide is used as a moisture and humidity indicator. It is also used as a catalyst.

調製方法 · 1 件

製造方法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.
