Chromium(III) fluoride Chemical Properties,Uses,Production
Chemical Properties
Chromium(III) fluoride [7788-97-8], CrF3, Mr 108.99. The anhydrous compound forms highly refractive rhombohedral crystals. It melts above 1000°C and is distinctly volatile between 1100 and 1200 °C. Chromium(III) fluoride is insoluble in water if no divalent chromium is present. Double compounds are formed with other metal fluorides, e.g., green CrF3 · 2KF·H2O.
Hydrates are known which contain three [16671-27-5] to nine [68374-27-6] molecules of water. The violet hexaaquochromium(III) fluoride, [Cr(H2O)6]F3, and its trihydrate, [Cr(H2O)6]F3 · 3H2O, can be obtained from hexaaquochromium(III) salt solutions and alkali fluorides. Products containing lesswater are green. The composition of the industrial product corresponds approximately to CrF3 · 3.5H2O and the product contains about 30 % chromium.
For the production of chromium(III) fluoride hydrate, chromium(III) oxide hydrate is dissolved in hot aqueous hydrofluoric acid and the green salt crystallizes. Chromium(III) fluoride is used in the textile industry for mordanting wool, for chromating dyestuffs, and in vigoureux printing. Chromium(III) fluorides have also found application in rust-prevention paints as corrosion inhibitors.
Uses
Some important uses are in printing and dyeing woolens; mothproofing of woolen materials; metal polishing; coloring marbles; and as a catalyst in halogenation reactions.
Preparation
Chromium(III) fluoride may be prepared by heating chromium trichloride under a stream of hydrogen fluoride:
The compound may be prepared by the reaction of chromium hydroxide with hydrofluoric acid:
Chemical Properties
Green crystalline powder or crystals
Physical properties
Dark green needles (anhydrous salt) or green hexagonal crystals (trihydrate); density 3.8 g/cm3 (anhydrous fluoride), 2.2 g/cm3 (trihydrate); anhydrous salt melts at 1,100°C and sublimes above this temperature; practically insoluble in water and ethanol (anhydrous salt); trihydrate sparingly soluble in water; soluble in HCl forming a violet solution.
Uses
Printing and dyeing woolens, moth-proofing, halogenation catalyst.
Uses
Used in the preparation of a mixed-metal fluoride catalyst for synthesis of HFC-134a.
General Description
Chromic fluoride solution is a green crystalline solid dissolved in water. CHROMIUM(III) FLUORIDE is corrosive to metals and tissue.
Air & Water Reactions
Water soluble.
Reactivity Profile
Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas.
Hazard
Irritant to skin and eyes, especially in solution.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Flammability and Explosibility
Not classified
Safety Profile
A poison by ingestion. A corrosive. When heated to decomposition it emits toxic vapors of Cr and F-.
