| | Chromic nitrate Usage And Synthesis |
| Description | Chromium nitrate is a crystalline substance, variously stated to be green brown or purple and existing in various hydrated forms. Molecular weight =238.03; 400.21(nonahydrate); Freezing/Melting point =60-100℃, depending on the degree of hydration. Hazard Identification (basedon NFPA-704 M Rating System): Health 1, Flammability 0,Reactivity 0. Soluble in water | | Chemical Properties | Chromium nitrate is a crystalline substance, variously stated to be green brown or purple and existing in various hydrated forms. | | Uses | 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. | | Safety Profile | 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. | | Potential Exposure | Chromium nitrate is used in the preparation of chrome catalysts, in textile printing operations; and as a corrosion inhibitor. Used to make other chemicals. | | First aid | If chromium nitrate gets into the eyes, removeany contact lenses at once and irrigate immediately for atleast 15 min, occasionally lifting upper and lower lids.Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and washimmediately with soap and water. Seek medical attentionimmediately. If this chemical has been inhaled, removefrom exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. | | storage | Color Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flammables and combustibles. Color Code—Blue: HealthHazard/Poison: Store in a secure poison location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Chromium nitrate must bestored to avoid contact with strong reducing agents, fuels,and ether since violent reactions occur. Store in tightlyclosed containers in a cool, well-ventilated area away fromflammable and combustible materials. A regulated, markedarea should be established where this chemical is handled,used, or stored in compliance with OSHA Standard1910.1045. See OSHA Standard 1910.104 and NFPA 43ACode for the Storage of Liquid and Solid Oxidizers fordetailed handling and storage regulations. | | Shipping | UN2720 Chromium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer | | Purification Methods | 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. | | Incompatibilities | 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. |
