Application

Chromium(III) chloride hexahydrate serves multiple purposes due to its versatile chemical properties. As greenish-black to violet deliquescent crystals, it is soluble in water and ethanol, with limited solubility in acetone and insolubility in ether. This compound is primarily used as a catalyst in various chemical reactions, such as the iodovinylation of aldehydes through the Takai reaction and the synthesis of chromium(III) complexes of tetradentate Schiff bases. Additionally, it plays a crucial role in creating Cr(III)-fatty acid complexes that act as catalysts in producing 1-monoacylglycerols, and in conjunction with choline chloride as a deep eutectic solvent, it facilitates the esterification of formic and acetic acid with alcohols. Chromium(III) chloride hexahydrate is also employed as a mordant and a chromium additive, contributing significantly to trivalent chromium plating and serving as a foundational material in the production of other chromium salts and chromium-containing pigments.
