General
Chemical Name: potassium iodide (KI)
Chemicals Description:
Chemical formula KI. Type the volume of 166.01. Colorless or white cubic crystal. Density of 3.13 grams / cm 3. Melting point 686 ℃, boiling point 1330 ℃. Highly soluble in water, ethanol, acetone and glycerol, aqueous light event of discolored, and precipitation of free iodine.
Uses: used to produce such as organic compounds and chemical reagents. Medical treatment for prevention and treatment of thyroid Arsenazo (large neck disease) and hyperthyroidism surgery. Also can be used for medicine and expectorant.
Content: This product is calculated according to the dry goods content of not less than 99.0 percent.
Characters:This product is colorless, transparent or white translucent hexagonal crystal or white granular powder, odorless, taste salty, bitter with a slight wet primer. In the wet air, easy deliquescence. Event of light and air can precipitate free iodine and yellow, in the acidic aqueous solution more yellowing; easily soluble in water, dissolved when the significant absorption of heat; soluble in ethanol, acetone, methanol, glycerol and ammonia; micro-soluble ether; potassium iodide aqueous solution was neutral or slightly alkaline.
Specification:CP2000
Uses
1, potassium iodide in the field of dermatology has some special purpose. Its mechanism was partly due to enhanced dissolution of necrotic tissue and digestion. KI also has antifungal activity. Clinical use it to treat Sporothrix disease, coloring bud Rhizobacteria disease, persistent erythema nodosum and nodular vascular go far. When the use of potassium iodide should also pay attention to its side effects, it will cause pustules, blisters, redness, eczema, urticaria and so on, acne can also increase, of course, can cause gastrointestinal reactions and mucosal symptoms.
2, in the medicine used for prevention and treatment of endemic goiter, and promote the absorption of vitreous opacity and expectorant. Preparation of iodide and potassium iodide is a dye material. Emulsifier used as a photo-sensitive, food additives, iodine and some insoluble metal iodide cosolvent. Can also be used as analytical reagents, chromatography analysis and point analysis of pain.
3, potassium iodide as a stabilizer and cosolvent.
4, feed grade potassium iodide as feed processing iodine supplements.
5, potassium iodide tablets.
6, measurements of ozone concentration, replacement of iodine starch blue, the reaction is as follows:
O3 +2 KI + H2O = 2KOH + O2 + I2
