What is VANDEX?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is SeO2 which has developed particularly rapidly in recent years. Do you know about SeO2?
- The official answer: Selenium dioxide, an oxide with the chemical formula SeO2, is a white crystalline powder with yellow-green vapour, soluble in water and polar organic solvents, used as an oxidizer for organic compounds, catalysts, chemical reagents, and raw materials for the manufacture of various inorganic selenium compounds.
What’s the application of VANDEX?
1, used in the production of electrolytic manganese metal 2, used in the production of sodium selenite 3, selenium dioxide used as an organic compound oxidizer, catalyst, chemical reagent, raw materials for the manufacture of various inorganic selenium compounds. Used as a special reagent of plant alkali, also can be used to precipitate zirconium, hafnium and preparation of selenium compounds and ammonia reaction to generate nitrogen and selenium, in the alcohol Chemicalbook solution to generate ethyl ammonium selenite [NH? (C?H5)SEO?], and hydrazine to generate nitrogen and black amorphous selenium, and hydroxylamine hydrochloride to generate nitrogen and red-brown amorphous selenium, and nitric acid to generate selenite. 4, selenium dioxide is used to make high-purity selenium and other selenium compounds. Also used in copiers, rectifiers, etc.
