화학적 성질

Potassium bromate is a white crystalline solid.

용도

Potassium Bromate is a dough conditioner that exists as white crystals or powder and is soluble in water. it exists in the anhydrous form as white granular powder and in the hydrated form as small white crystals or granules. it is used to age and improve the baking properties of flour. it is used with potassium iodate and azodicarbon- amide to modify the protein in bread flour to promote the desired properties of loaf volume and shape. it is used in baked goods.

일반 설명

A white crystalline solid.

공기와 물의 반응

Water soluble.

반응 프로필

Potassium bromate is a strong oxidizing agent. Forms very flammable mixtures with combustible materials. Such mixtures may be explosive if the combustible material is finely divided and are often ignitable by friction. A mixture with finely divided aluminum can explode by heat, percussion, and friction [Mellor 2:310. 1946-47]. Reacts explosively with selenium [Mellor 2 Supp1:763. 1956]. Prolonged exposure to fire or heat can result in an explosion .

위험도

Dangerous fire risk in contact with organic materials, strong irritant. Possible carcinogen.

건강위험

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

화재위험

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. A poison by ingestion. A powerful oxidzer. An irritant to skin, eyes, and mucous membranes. Mutation data reported. Wxtures with sulfur may ignite. Violent reaction with Al, Al + dmitrotoluene @ 290°, As, C, Cu, Pb(C2H3O2)2, metal sulfides, organic matter, P, S. Aqueous solutions react violently with selenium. When heated to decomposition it emits very toxic fumes of Brand K2O. See also BROMIDES.

잠재적 노출

Potassium bromate is used as animal feed additive, food additive; flavor and packaging material; as a laboratory reagent; an oxidizing agent.

UN1479 Potassium bromate, Hazard Class: 5.1; Labels: 5.1-Oxidizer.

Purification Methods

Crystallise KBrO3 from distilled H2O (2mL/g) between 100o and 0o. To remove bromide contamination, a 5% solution in distilled H2O, cooled to 10o, is bubbled with gaseous chlorine for 2hours, then filtered and extracted with reagent grade CCl4 until colourless and odourless. After evaporating the aqueous phase to about half its volume, it is cooled again slowly to about 10o. The crystalline KBrO3 that separates, is washed with 95% EtOH and dried in a vacuum [Boyd et al. J Am Chem Soc 74 237 1952]. Another way to remove Br-ions is by stirring several times in MeOH and then drying at 150o [Field & Boyd J Phys Chem 89 3767 1985].

비 호환성

A strong oxidizer.Violent reaction with many compounds, including reducing agents; chemically active metals; combustible materials, strong acids, alkaline earth sulfides, aluminum carbides, aluminum, amines, calcium sulfide, carbides, chlorine trifluoride, glycerin, hydrides, hydrochloric acid, hydrogen peroxide, hydrogen sulfide, hydroxylamine, magnesium, metal powders, metal sulfides, molybdenum, phenylhydrazine, phosphorous red/ friction, phosphorous trichloride, silicon, sulfides, sulfur, sulfur dioxide, sulfur/friction, sulfuric acid, tungsten, hydrogen trisulfide. Incompatible with aluminum, copper.
