Chemische Eigenschaften
Chromium nitrate is a crystalline substance, variously stated to be green brown or purple and existing in various hydrated forms.
Verwenden
Catalyst, corrosion inhibitor.
Definition
ChEBI: An inorganic nitrate salt consisting of chromium and nitrate in which the ratio of chromium (in the +3 oxidation state) to nitrate is 1:3
Hazard
May ignite organic materials on contact;
may be explosive when shocked or heated; powerful
oxidizer. Very toxic.
Sicherheitsprofil
Poison by
intraperitoneal route. Moderately toxic by
subcutaneous and ingestion routes.
Mutation data reported. Questionable
carcinogen. When heated to decomposition
it emits toxic fumes of NOx and Cr.
mögliche Exposition
Chromium nitrate is used in the preparation of chrome catalysts, in textile printing operations; and as a corrosion inhibitor. Used to make other chemicals.
Versand/Shipping
UN2720 Chromium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer
läuterung methode
Filter off the salt and wash it with CCl4 in a closed system under N2, and dry it in vacuo. It is very soluble in H2O, EtOAc and Me2SO but insoluble in *C6H6, CCl4 and CHCl3. The deliquescent powder reacts vigorously with Et2O. [Addison & Chapman J Chem Soc 539 1964.] Cr(VI) ions are carcinogenic as they cause DNA breaks, and Cr(III) ions affect DNA synthesis.
Inkompatibilitäten
This chemical is a strong oxidizer. Contact with reducing agents; fuels, ethers, and other flammable and combustible materials cause a fire and explosion hazard. Violent reaction with many compounds, including reducing agents; alcohols, 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 Chromium Nitrate 845 dioxide, sulfur/friction, sulfuric acid, tungsten, hydrogen trisulfide
Waste disposal
Precipitate chromium as the hydroxide. Dewater the sludge and dispose of in singlepurpose dumps.
