RHENIUM(III) CHLORIDE

Dark-red solid, on heating emits green vapor from which the metal may be deposited, non- electrolyte in solution, soluble in water and glacial acetic acid.

It is used as a starting material for synthesis of rhenium complexes. ReCl3can react with peralkylated benzene-metal complexes that act as electron reservoirs.

reagent type: catalyst
core: rhenium

Poison by intraperitoneal route. When heated to decomposition it emits toxic fumes of Cl-. See also RHENIUM and CHLORIDES.

A rhenium trichloride preparation method: rhenium powder is evenly filled in the atmosphere furnace, the thickness is maintained at 2cm, the furnace temperature is raised to 100 , held for 2h, through the chlorine, control the gas flow rate of 1m3/h, and then, with a heating rate of 20 /min, slowly raised to 300 , reaction 10h, natural cooling, when the temperature is lowered to 200 , to stop the passage of chlorine, replaced by the passage of nitrogen When the temperature was lowered to 200, the chlorine gas was stopped and replaced by nitrogen gas, the gas flow rate of nitrogen was 3m3/h, the reaction was 3h, and the reaction was naturally cooled to room temperature, and the product was rhenium trichloride analyzed by X-ray diffraction detection and the yield was 85%.
Thermal decomposition of rhenium pentachloride in nitrogen gas: ReCl5 ReCl3 + Cl2. direct sunlight should be avoided, otherwise chlorine oxides will be generated. Yield is generally about 60% to 65%.
