Description
Chromic nitrate, also known as chromium trinitrate, is 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. It is a crystalline substance, variously described as green, brown, or purple, and exists in various hydrated forms.
Uses
Used in Chemical Industry:
Chromic nitrate is used as a catalyst for various chemical reactions due to its ability to facilitate and increase the rate of these reactions without being consumed in the process.
Used in Industrial Applications:
Chromic nitrate is used as a corrosion inhibitor, particularly in the protection of metals from corrosion. Its ability to form a protective layer on metal surfaces helps to prevent the oxidation and degradation of these materials, making it a valuable additive in various industrial applications.
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.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 13548-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,4 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13548-38:
(7*1)+(6*3)+(5*5)+(4*4)+(3*8)+(2*3)+(1*8)=104
104 % 10 = 4
So 13548-38-4 is a valid CAS Registry Number.
