| Physical and Chemical Properties | Ruthenium trichloride is a red-brown or black leaf-like crystal, which is easily deliquescent. Relative density of 3.11, more than 500 deg C when the solution to the simple matter. Insoluble in cold water and carbon disulfide, hot water decomposition, difficult to dissolve in ethanol, soluble in hydrochloric acid. And potassium iodide solution to generate iodide precipitation, hydrogen sulfide into the solution when the precipitation of ruthenium trisulfide, with ammonia, potassium cyanide and potassium nitrite and other complexing agents to form the corresponding ammonia, cyanide, and nitroso complexes, with sodium amalgam or titanium trichloride is reduced to a blue divalent ruthenium ion. |

Ruthenium (Ⅲ) chloride - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Quality index | ruthenium content is the main index of ruthenium trichloride product, which is the basis of the dosage of ruthenium trichloride in use. The solid trifluoro-nail crystals have one or two crystal forms of α-and β, whereas the α-form of ruthenium trichloride is insoluble and inactive. Ruthenium trifluoride used in the production of metal anode coatings must be soluble. Active beta-form. The control of one or two crystal forms of ruthenium trichloride of α-and β is completely determined by the preparation process. If the ruthenium content is too high, insoluble α-type ruthenium trichloride may be produced. Because solid ruthenium trichloride is easy to absorb moisture, the water contained is uncertain. When the ruthenium content is lower than a certain value, the water content is large, so that ruthenium trichloride is easy to be attached to the wall, which is not conducive to use. General production units are controlled according to 36% ~ 37%, taking into account the use and production of two factors, determine the solid ruthenium content of ruthenium trifluoride requirements in 35% ~ 38%. |
| Use | use as a spectral purity reagent use 1, A catalyst for the oxidative cyclization of 7-dienes to form oxo-heterocycloheptanediol. The tertiary hydrocarbon bond of the cyclic ether is hydroxylated with periodate or bromate. |
| production method | 1.Α-rucl3 (1) in a borosilicate heat-resistant glass reaction tube, the mixture of chlorine and carbon monoxide (Cl2: CO = 3: 1, volume ratio) was introduced into 0.25~3g of metal ruthenium powder, and heated at 600 ℃ for 12h, the product was washed with ethanol to remove about 0.2% of the Ru2OCl6, followed by heating at 600 °c for 3H in a stream of chlorine. (2) the first synthesis of β-RuCl2, and then in the flow of chlorine or argon heating (argon 450 deg C for 8H, chlorine 650 deg C for 2H). (3) in a borosilicate heat-resistant glass reaction tube, 2g of the synthesized β-RuCl3 was placed and heated at 650 ° C. In a stream of chlorine gas. At this temperature, traces of Ru2OCl6 (purple) will sublimate. After that, α-RuCl3 was sublimated at 730 ° C., and crystals were precipitated after separation from Ru2OCl6. 2.Β-rucl3 in The borosilicate heat-resistant glass reaction tube, put 0.5g of sponge-like metal ruthenium, and inject mixed gas of chlorine and carbon monoxide (Cl2: CO = 3: 1)(volume ratio), at the same time in 330~340 deg C when heating 4~6H. The resultant was crushed gently, heated in a mixed gas at 330 to 340 ° C. For 6 to 8H, and then cooled. Preferably, it is carried out in a stream of chlorine gas upon heating to the reaction temperature or upon cooling. In the product obtained by this method, unreacted Ruthenium was not detected, but the content of α-RuCl3 therein was about 1% to 2% (estimated value based on measurement of magnetic susceptibility). |
