Selenium dioxide Application
1.Oxidant and catalyst for making high-purity selenium and other selenium compounds, organic synthetic drugs.
2. Used as a special reagent for plant alkaloids, which can be used to precipitate zirconium, hafnium and prepare selenium compounds
3. Used as an organic compound oxidant, catalyst, chemical reagent, raw material for the manufacture of various inorganic selenium compounds. Can be used in copiers, rectifiers, etc.
4. Manufacture of other selenium compounds, alkaloid test, oxidizing agent. It reacts with ammonia to form nitrogen and selenium, in alcohol solution it generates ethyl ammonium selenite [NH₄ (C₂H5) SeO₃], and hydrazine generates nitrogen and black amorphous selenium , With hydroxylamine hydrochloride to form nitrogen and red-brown amorphous selenium, and nitric acid to generate selenite.
