Potassium iodide

요오드화 칼륨 C화학적 특성, 용도, 생산

화학적 성질

White crystals, granules, or powder; strong, bitter, saline taste. Soluble in water, alcohol, acetone, and glyc- erol.

용도

manufacture of photographic emulsions; in animal and poultry feeds to the extent of 10-30 parts per million; in table salt as a source of iodine and in some drinking water; also In animal chemistry. In medicine,potassium iodide is used to regulate the thyroid gland.

용도

Potassium Iodide is a source of iodine and a nutrient and dietary supplement. it exists as crystals or powder and has a solubility of 1 g in 0.7 ml of water at 25°c. it is included in table salt for the preven- tion of goiter.

용도

Potassium iodide is a white crystal, granule or powder made by the reaction of iodine with hot potassium hydroxide solution followed by crystallization. It is very soluble in water, alcohol, and acetone. Potassium iodide was first used as the primary halide in Talbot’s calotype process, then in the albumen on glass process followed by the wet collodion process. It was also used as a secondary halide in silver bromide gelatin emulsions.

정의

potassium iodide: A white crystallinesolid, KI, with a strong bittertaste, soluble in water, ethanol, andacetone; cubic; r.d. 3.13; m.p. 681°C;b.p. 1330°C. It may be prepared bythe reaction of iodine with hot potassiumhydroxide solution followed by separation from the iodate (which isalso formed) by fractional crystallization.In solution it has the interestingproperty of dissolving iodine to formthe triiodide ion I3-, which is brown.Potassium iodide is widely used as ananalytical reagent, in photography,and also as an additive to table salt toprevent goitre and other disordersdue to iodine deficiency.

정의

A compound that contains pentavalent iodine, which is usually ionically bound to electropositive atoms.

상표명

Iosat (Anbex); Thyro-Block (Medpointe); Thyrosafe (R R Registrations); Thyroshield (Fleming).

공기와 물의 반응

Water soluble.

반응 프로필

Bromine trifluoride rapidly attacks the following salts: barium chloride, cadmium chloride, calcium chloride, cesium chloride, lithium chloride, silver chloride, rubidium chloride, potassium bromide, potassium chloride, Potassium iodide, rhodium tetrabromide, sodium bromide, sodium chloride, and sodium iodide [Mellor 2, Supp. 1:164, 165. 1956].

건강위험

May irritate eyes or open cuts.

Clinical Use

Potassium iodide is used to treat the cutaneous lymphatic form of sporotrichosis, although newer agents are also effective in this disorder and may be better tolerated tolerated. The drug is also used for erythema nodosum and nodular vasculitis.

Safety Profile

Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. Human teratogenic effects by ingestion: developmental abnormalities of the endocrine system. Experimental teratogenic and reproductive effects. Mutation data reported. Explosive reaction with charcoal + ozone, trifluoroacetyl hypofluorite, fluorine perchlorate. Violent reaction or ignition on contact with dazonium salts, diisopropyl peroxydicarbonate, bromine pentafluoride, chlorine trifluoride. Incompatible with oxidants, BrF3, FClO, metaltic salts, calomel. When heated to decomposition it emits very toxic fumes of K2O and I-. See also IODIDES.

Purification Methods

Crystallise it from distilled water (0.5mL/g) by filtering the near-boiling solution and cooling. To minimise oxidation to iodine, the process can be carried out under N2 and the salt is dried under a vacuum over P2O5 at 70-100o. Before drying, the crystals can be washed with EtOH or with acetone followed by pet ether. It has also been recrystallised from water/ethanol. After 2 recrystallisations, ACS/USP grade had Li and Sb at <0.02 and <0.01 ppm respectively. [Lingane & Kolthoff Inorg Synth I 163 1939.]
