Anwendungen & Verwendung
Verwenden
Rhodium(III) Chloride is used in homogeneous catalysis, for example in the industrial prodcution of acetic acid. It is used to coat optic fibres and optical mirrors, and for crucibles, thermocouple elements and headlight reflectors. manufacture of rhodium trifluoride.
Herstellung & Synthese
synthetische
Rhodium trichloride is prepared by heating rhodium with chlorine gas at 250°C:2Rh + 3Cl2 → 2RhCl3Also, the chloride salt may be obtained by treating the yellow hydrous oxide, Rh2O3.5H2O, with hydrochloric acid. The solution is carefully evaporated to form a dark red and water-soluble salt, rhodium trichloride tetrahydrate, RhCl3.4H2O. Heating the tetrahydrate in a stream of hydrogen chloride gas at 180°C forms the anhydrous salt, RhCl3.
