Selenium dioxide
CAS No.7446-08-4
Alias:Selenious acid anhydride;SELENIOUS ANHYDRIDE;SELENIUM AA/ICP CALIBRATION/CHECK STANDARD;SELENIUM AA SINGLE ELEMENT STANDARD;
Molecular formula：O2Se
Molecular weight：110.96
Structural formula：
1. Performance and use:
White or light yellow monoclinic or tetragonal crystal system crystals, hygroscopic and irritating acidic smell. Soluble in water, ethanol, acetone, acetic acid and benzene.
Uses Used in the production of high-purity selenium and other selenium compounds, or organic synthesis of drugs oxidants and catalysts Used as organic compounds oxidants, catalysts, chemical reagents, a variety of inorganic selenium compounds manufacturing raw materials. It is also used in photocopiers and rectifiers.
Uses 1, used in the production of electrolytic manganese metal 2, used in the production of sodium selenite 3, selenium dioxide is used as organic compounds oxidants, catalysts, chemical reagents, a variety of inorganic selenium compounds manufacturing raw materials. Used as a special reagent for plant bases, can also be used for the precipitation of zirconium, hafnium and the preparation of selenium compounds and ammonia to generate nitrogen and selenium, in alcohol solution to generate ethylammonium selenite [NH?(C?H5)SeO?], with hydrazine to generate nitrogen and black amorphous selenium, with hydroxylamine hydrochloride to generate nitrogen and reddish-brown amorphous selenium, nitric acid and selenous acid.4, selenium dioxide is used in the production of high-purity selenium and other selenium compounds. It is also used in photocopiers and rectifiers.
Used in the manufacture of other selenium compounds, alkaloid determination, oxidising agent. React with ammonia to generate nitrogen and selenium, in alcohol solution to generate ethylammonium selenite [NH4(C2H5)SeO3], with hydrazine to generate nitrogen and black amorphous selenium, with hydroxylamine hydrochloride to generate nitrogen and reddish-brown amorphous selenium, with nitric acid to generate selenious acid.
