Usage

Chemical Properties

red-brown to dark brown crystalline powder, easily soluble in water, hydrochloric acid, alcohol and alkali solution, insoluble in ether and aqua regia, lose crystal water by strong heat and become insoluble, and then decompose into rhodium and chlorine.

Uses

Rhodium(III) chloride hydrate is used as a catalyst to prepare acetic acid. It is also used as a catalyst for the isomerization of alkenes, the reduction of aromatic rings, the oxidation ofalkenes, the hydration of acetylene. It is involved in the hydrosilylation of α,β-unsaturated esters to form dimethylketene trimethylsilyl acetals.

Application

Rhodium(III) chloride is often used in synthetic chemistry as a hydrogenation catalyst. Rhodium(III) chloride is also used to make transition metal complexes, some of which are used as reagents in the decarbonylation dehydration reactions of fatty acids to alkenes.
