Iodic acid potassium salt

요오드산 칼륨 C화학적 특성, 용도, 생산

화학적 성질

white crystals or powder

용도

Oxidizer used recently to form 2-styrylchromones from o-hydroxy-ω-cinnamylideneacetophenones by oxidative cyclization.1

용도

Oxidizing agent in volumetric chemical analysis; as maturing agent and dough conditioner.

용도

Potassium Iodate is a source of iodine made by reacting iodine with potassium hydroxide. it is a crystalline powder which is more stable than iodide. it has a solubility of 1 g in 15 ml of water. it is used as a fast-acting dough improver; it is used with potassium bromate as an oxidizing agent to modify the protein in bread flour which pro- motes loaf volume and shape. it is used in baked goods.

정의

A white solid formed either by adding iodine to a hot concentrated solution of potassium hydroxide or by the electrolysis of potassium iodide solution. No hydrates are known. It is a source of iodide and iodic acid. When treated with a dilute acid and a reducing agent, the iodate ions are reduced to iodine.

정의

potassium iodate: A white crystallinesolid, KIO3, soluble in waterand insoluble in ethanol; monoclinic;r.d. 3.9; m.p. 560°C. It may be preparedby the reaction of iodine withhot concentrated potassium hydroxideor by careful electrolysis ofpotassium iodide solution. It is anoxidizing agent and is used as ananalytical reagent. Some potassiumiodate is used as a food additive.

주요 응용

Potassium iodate is a fairly strong oxidizing agent that may be used in the assay of a number of pharmaceutical substances, for instance : benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride and the like. Under appropriate experimental parameters the iodate reacts quantitatively with both iodides and iodine. It is, however, interesting to observe here that the iodate titrations may be carried out effectively in the presence of saturated organic acids, alcohol and a host of other organic substances.
The oxidation-reduction methods with potassium iodate invariably based on the formation of iodine monochloride (ICl) in a medium of strong hydrochloric acid solution.

Food additive

Iodine can be added to salt in the form of potassium iodide (KI) or potassium iodate (KIO3). Because KIO3 has higher stability in the presence of salt impurities, humidity, and porous packaging, it is the recommended form.
Potassium iodate, which is formed as a secondary product, is reduced by activated carbon. The product is purified by crystallization from water. Alternatively, iron (II) iodide, prepared by using iron powder and iodine, can be treated with potassium carbonate to obtain potassium iodide. High-purity potassium iodide can be prepared by the reaction of a potassium bicarbonate with hydriodic acid.

Safety Profile

Poison by ingestion and intraperitoneal routes. A trace mineral added to animal feeds. Potentially explosive reaction with charcoal + ozone, metals (e.g., powdered aluminum, copper), arsenic carbon, phosphorus, sulfur, alkali metal hydrides, alkaline earth metal hydrides, antimony sulfide, arsenic sulfide, copper sulfide, tin sulfide, metal cyanides, metal thiocyanates, manganese dioxide, phosphorus. Violent reaction with organic matter. When heated to decomposition it emits very toxic fumes of I and K2O. See also IODATES.

Overdosage

Overdose of potassium iodate, an iodized salt used for iodine supplementation in areas endemic for goiter, has been shown to cause profound visual loss and extensive retinal pigmentary abnormalities.78 FA reveals RPE window defects and ERG and VEP testing show marked impairment of retinal function. Visual acuity may improve slowly over several months.

Purification Methods

It has been crystallised twice from distilled water (3mL/g) between 100o and 0o, dried for 2hours at 140o and cooled in a desiccator. Analytical reagent grade material dried in this way is suitable for use as an analytical standard.
