Chromium(III) acetylacetonate Chemical Properties,Usage,Production

Uses

Chromium(III) acetylacetonate is a useful research chemical.

Chemical Properties

PURPLE CRYSTALLINE POWDER

Uses

Catalyst in the oxidation of methacrylic esters by hydrogen peroxide, MOCVDChromium(III) 2,4-pentanedionate is used in the reduction of detonation of nitromethane. It is also used in NMR spectroscopy as a relaxation agent due to its solubility in nonpolar organic solvents and its paramagnetism. Further, it is involved in the modification of the surface properties of solid polyurethanes.

Uses

Chromium(III) acetylacetonate may be used as an active site in the formation of redox systems for the fabrication of flow batteries. It may also be used as a precursor for chromium nitride based metallic coatings.

General Description

Chromium(III) acetylacetonate is an acidopentamminechromium (111) salt, which is a crystalline material that can be prepared by treatment of precipitated hydrous chromium(III) oxide with acetylacetone.

Flammability and Explosibility

Not classified

Safety Profile

Moderately toxic by ingestion. Mildly toxic by s h contact. When heated to decomposition it emits acrid smoke and irritating fumes. See also CHROMIUM COMPOUNDS.

Purification Methods

Purify it by dissolving 6g in hot *C6H6 (20mL) and adding 75mL of pet ether slowly. Cool to room temperature then chill on ice, filter off and dry in air to give 2.9g. It also crystallises from EtOH. It is soluble in heptane, *C6H6, toluene and pentane-2,4-dione at 20-40o. It forms a 1:2 complex with CHCl3.
