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