Tungsten oxychloride can be obtained by heating tungsten oxide tungsten (Ⅵ) and tungsten chloride (Ⅵ) to a certain temperature; it is long red needles, extremely sensitive to atmospheric moisture, may be harmful to the environment, and the water should be given attention.
Property and Stability of Tungsten Oxychloride
1. Tungsten oxychloride can relatively dissolve in organic solvents;
2. Generate a dark red solution in dioxane and acetone;
3. Generate blue-green solution in cyclohexanone;
4. It gives off hydrogen chloride and generate a clear solution in the ethanol and dimethoxyethanol;
5. Tungsten oxychloride (Ⅵ) will react violently and form a colorless solution in ammonia or sodium hydroxide solution;
6. It will react with water, hydrochloric acid and nitric acid to produce a yellow-green precipitate;
7. It is soluble in CS2, S2Cl2, benzene, and decomposed in cool and hot water.
