Beschreibung

Anwendung

Chromium(III) chloride (CrCl₃. 6H₂O) hexahydrate can be used:

• As a source of chromium(II), which is in turn used as a catalyst in iodovinylation of aldehydes (Takai reaction).
• In the synthesis of chromium(III) complexes of tetradentate Schiff bases.
• In the preparation of Cr(III)-fatty acid complexes which can further be used as a catalyst for the synthesis of 1-monoacyIgIyceroIs.
• In combination with choline chloride as a deep eutectic solvent, which can be utilized as a catalyst for the esterification of formic and acetic acid with alcohols.
