 Rhodium trichloride (CAS NO.10049-07-7) can be used as catalysts.

 Rhodium trichloride (CAS NO.10049-07-7) is produced by the action of hydrochloric acid on hydrated rhodium(III) oxide. RhCl₃(H₂O)₃ can be crystallized from a solution in concentrated hydrochloric acid. This method helps to remove nitrogen-containing impurities. RhCl₃ is prepared by reaction of chlorine with rhodium sponge at 200-300°C. The corresponding reaction in molten sodium chloride affords Na₃RhCl₆.
