Chemical Properties

Rhodium(III) Chloride, also known as rhodium trichloride, is a red-brown or black crystalline powder that is easily deliquescent. poisonous! Molecular weight 209.26 (anhydrous), melting point 450~500°C (decomposition). Boiling point 800°C (sublimation). To 600°C above to generate polyfluoride. It can be reduced by hydrogen at 70°C. Insoluble in water, acid, aqua regia, soluble in methanol and cyanide solution. In concentrated acid (nitric acid, sulfuric acid) heating decomposition. When heated, it can interact with metals such as sodium, aluminum, magnesium, and iron.

Physical properties

Brownish-red powder; deliquescent; decomposes on heating at 450 to 500°C; sublimes at 800°C; insoluble in water, water-solubility, however, depends on the method of preparation; soluble in alkali hydroxide or cyanide solutions; soluble in aqua regiaThe trihydrate is a dark red powder; deliquescent; loses water at 100°C; very soluble in water; soluble in alcohol and hydrochloric acid; insoluble in ether.

Uses

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.

Application

Rhodium(III) chloride precursor may be used to dope graphene with Rh nanoparticles to prepare hybrids for electrocatalysis in energy, sensing and biomedical sectors. It can be used to prepare [Rh(NH3)6]Cl3.

Preparation

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.

Reactions

Catalyst in conjunction with "pybox" for the asymmetric hydrosilylation of ketones.C-C bond forming reactions.

Hazard

Toxic by ingestion.

Safety Profile

Poison by ingestion, intraperitoneal, and intravenous routes. Experimental reproductive effects. Questionable carcinogen with experimental carcinogenic data. Mutation data reported. Incompatible with pentacarbonyl iron + zinc. When heated to decomposition it emits toxic fumes of Cl-. See also RHODIUM and CHLORIDES

Potential Exposure

Rhodium trichloride is used in hydrosilylation, hydrogenation, carbonylation, oxidation, arylation. See also “Rhodium Metal.” In plating operations and in catalyst preparation, the metal will be used as the trichloride.

Shipping

UN3260 Corrosive solid, acidic, inorganic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

Purification Methods

Probable impurities are KCl and HCl. Wash the chloride well with small volumes of H2O to remove excess KCl and KOH and dissolve it in the minimum volume of conc HCl. Evaporate it to dryness on a steam bath to give wine-red coloured RhCl3.3H2O. Leave it on the steam bath until the odour of HCl is lost-do not try to dry further as it begins to decompose above 100o to the oxide and HCl. It is not soluble in H2O but soluble in alkalis or CN solutions and forms double salts with alkali chlorides. [Anderson & Basolo Inorg Synth VII 214 1963.]

Incompatibilities

Sensitive to humidity. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materi- als, strong bases, strong acids, oxoacids, and epoxides.

Waste Disposal

Recovery and reclaiming wherever possible in view of high economic value. See “Rhodium Metal.”

Check Digit Verification of cas no

The CAS Registry Mumber 10049-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10049-07:
(7*1)+(6*0)+(5*0)+(4*4)+(3*9)+(2*0)+(1*7)=57
57 % 10 = 7
So 10049-07-7 is a valid CAS Registry Number.

Separation and characterization of new transition metal complexes of some chromone derivatives

Youssef, Nabil S.

, p. 225 - 238 (2000)

Transition metal complexes of two new ligands derived from the condensation of 6-formyl-7-hydroxy-5-methoxy-2-methylchromone with barbituric acid (H2L1) and 6-formyl-5,7-dihydroxy-2-methylchromone with thiobarbituric acid (H3/s

Kinetic studies on the oxidation of dichlorotetracarbonyldirhodium(I) by hydrogen peroxide

Chipperfield, John R.,Shana'a, May,Webster, David E.

, p. 511 - 522 (1988)

Kinetic measurements on the oxidation of dichlorotetracarbonyldirhodium(I) by hydrogen peroxide in ethanol/hydrochloric acid indicate that reaction proceeds through the intermediate "".The reaction rate is first order with respect to the rhodiu

Thermodynamic Properties of Ruthenium and Rhodium Chlorides

Tagirov,Makarov,Bryukvin

, p. 919 - 921 (2008/10/08)

Thermodynamic properties of ruthenium and rhodium trichlorides were studied by high-temperature mass spectrometry from 591 to 724 and 500 to 683 K, respectively. RuCl3 and RhCl3 dissociate to metal at these temperatures. The dissociation pressures of RuCl3 and RhCl3 were measured. No ruthenium or rhodium chlorides were found in the gas phase.
