Rhodium (III) chloride trihydrate

Description

Rhodium trichloride is an odourless, red-brown to black crystalline powder. It is corrosive to steel and aluminium. It is hygroscopic and absorbs moisture or water from the air. It is incompatible with strong oxidising agents. On decomposition, rhodium trichloride emits hydrogen chloride, carbon monoxide, carbon dioxide, and rhodium/rhodium oxides.

Chemical properties

Rhodium trichloride is a red-brown or black, odorless solid or liquid

Potential Exposure

Rhodium trichloride is used in hydro- silylation, hydrogenation, carbonylation, oxidation, aryla- tion. See also “Rhodium Metal.” In plating operations and in catalyst preparation, the metal will be used as the trichloride.
