Chromyl chloride Usage And Synthesis
Chemical PropertiesDEEP RED LIQUID
Chemical PropertiesChromyl chloride is a dark red fuming liquid with a musty, burning odor.
Physical propertiesDark red, fuming liquid; reddish yellow vapors; musty buring odor; density 1.91 g/mL; freezes at -96.5°C; boils at 117°C; reacts with water; soluble in chloroform, carbon tetrachloride, benzene, carbon disulfide and nitrobenzene.
UsesIn organic oxidations and chlorinations; as a solvent for chromium oxide; in making chromium complexes and dyes
UsesCatalyst for polymerization of olefins; oxidation of hydrocarbons; in the Etard reaction for production of aldehydes and ketones; in the preparation of various coordination complexes of Cr.
UsesHighly spin-polarized chromium dioxide (CrO2) thin films were deposited on 100 TiO2 substrates by chemical vapor deposition using chromyl chloride as a precursor. Chromyl chloride (Cr02C12) reacts with cyclohexane solvent at 75 OC to give a dark precipitate along with chlorocyclohexane and a small amount of cyclohexene (in 10.0 and ca. 0.3% yields based on chromium). Chromyl chloride, CrO2C12, oxidizes cyclooctane, isobutane, and toluene under mild conditions (25-60" C). The reactions give chlorinated products (chlorocyclooctane, tert- butyl chloride, and benzyl chloride) and a dark chromium-containing precipitate. Used for Organic oxidations and chlorination, chromium coordination complexes, catalyst for polymerization of olefins. Chromyl chloride in carbon tetrachloride solution reacts in the cold with cyclohexene, cyclopentene, and 1-hexene to give the various isomeric chlorohydrins as the major products.
PreparationChromyl chloride is prepared by reacting chromium(III) chloride with hydrochloric acid:
CrO3 + 2HCl → CrO2Cl2 + H2O
Also, it may be prepared by warming potassium dichromate with potassium chloride in concentrated sulfuric acid:
K2Cr2O7 + 4KCl + 3H2SO4 → 2Cr2O2Cl2 + 3K2SO4 + 3H2O.
DefinitionA dark red covalent liquid prepared either by distilling a dry mixture of potassium dichromate and sodium chloride with concentrated sulfuric acid or by the action of concentrated sulfuric acid on chromium(VI) oxide dissolved in concentrated hydrochloric acid. Chromyl chloride is hydrolyzed by water, and with solutions of alkalis it undergoes immediate hydrolysis to produce chromate ions. It is used as an oxidizing agent in organic chemistry. Chromyl chloride oxidizes methyl groups at the ends of aromatic side chains to aldehyde groupings (étard’s reaction).
General DescriptionA dark red fuming liquid with a pungent odor. Corrosive to tissue.
Reactivity ProfileChromyl chloride is a powerful and often violent oxidizing agent. Reacts readily with many inorganic and organic materials in the absence of a dilutent. Contact with hydrogen sulfide or phosphine can cause ignition. Contact with phosphorus tribromide, acetone, ethanol, ether, and turpentine causes ignition. Contact with moist phosphorus or with phosphorus trichloride leads to explosive reaction. Contact with ammonia causes incandescence. Reacts with sodium azide to form chromyl azide, which is explosive in the absence of a dilutent. Causes ignition of flowers of sulfur and of urea on contact. [Bretherick, 1979, p. 822-823].
HazardCorrosive to tissue. Strong oxidizing agent. Skin and upper respiratory tract irritant. Probable carcinogen.
Health HazardInhalation causes severe irritation of upper respiratory system. Contact with eyes or skin causes irritation and burning. Ingestion causes burning of mouth and stomach.
Fire HazardBehavior in Fire: Vapors are very irritating to eyes and mucous membranes. May increase severity of fire.
Safety ProfileSuspected carcinogen. Probably a poison by various routes. Mutation data reported. Corrosive. A strong irritant. Hydrolyzes to form chromic and hydrochloric acids. A strong oxidner and chlorinating agent. Violent reaction with water. Reacts violently with alcohol, ether, acetone, turpentine. Ignites or explodes on contact with nonmetal halides (e.g., disulfur dichloride, phosphorus trichloride, and phosphorus tribromide), nonmetal hydrides (e.g., hydrogen sulfide and hydrogen phosphide), flowers of sulfur, moist phosphorus, sodium azide, and urea. During preparation can violently explode. Incompatible with ammonia, disulfur dichloride, organic solvents, phosphorus, phosphorus trichloride, sodium azide, and sulfur. When heated to decomposition it emits toxic fumes of Cl-. See also CHROMIUM COMPOUNDS.
Potential ExposureChromium oxychloride is used in making chromium complexes and dyes; and used in various organic oxidation and chlorination reactions
ShippingUN1758 Chromium oxychloride, Hazard class: 8; Labels: 8-Corrosive material.
Purification MethodsPurify it by distillation under reduced pressure. It hydrolyses violently with H2O and is a powerful oxidant which explodes with P, and ignites in contact with S, NH3, EtOH and many organic compounds. TOXIC.
IncompatibilitiesContact with water is violent and forms hydrochloric and chromic acids, and chlorine gas. A powerful oxidizer. Reacts violently with acetone, alcohol, ammonia, ether, fuels, organic solvents, moist phosphorus, phosphorus trichloride; sodium azide; sulfur, reducing agents; turpentine. Contact with nonmetal halides, such as disulfur dichloride, phosphorus trichloride; and phosphorus tribromide; nonmetal hydrides, such as hydrogen sulfide; hydrogen phosphide, and urea, causes a danger fire and explosion hazard
