Basic Information
Product Name: Selenium dioxide
CAS Number: 7446-08-4
Molecular Formula: SeO2
Molecular Weight: 110.96
Appearance: It is a white or slightly red - colored, shiny, acicular crystal with a pungent odor.
Density: 3.954 g/cm³.
Melting Point: 340 - 350ºC.
Solubility: It is highly soluble in water, forming selenous acid. It is also soluble in organic solvents such as ethanol and acetone.
Uses
Inorganic Synthesis: It serves as an important reagent in inorganic synthesis, being used to prepare various selenium - containing compounds. For example, it can be used to synthesize selenates and selenites.
Organic Synthesis: In organic chemistry, it is widely employed as an oxidizing agent. It can oxidize alcohols to aldehydes or ketones, and is also used in some specific reactions to introduce oxygen - containing functional groups. For instance, it can oxidize the α - methyl group of ketones to form α - keto acids.
Glass Industry: Added to glass, it can act as a decolorizing agent and a clarifying agent. It helps to remove the greenish - yellow color of glass caused by iron impurities, thereby improving the transparency and quality of the glass.
Electronics Industry: It is used in the production of some electronic components. For example, it is involved in the manufacturing process of semiconductor materials, where it can be used for doping or surface treatment to adjust the electrical properties of the materials.
Safety Information
Toxicity: Selenium dioxide is toxic. Inhalation, ingestion, or skin contact with it can cause harm to the body. It may irritate the respiratory tract, eyes, and skin, and long - term exposure can lead to selenium poisoning, which affects the nervous system, liver, and other organs.
Protective Measures: When handling selenium dioxide, appropriate protective equipment should be worn, including gloves, goggles, and masks. Operations should be carried out in a well - ventilated environment to avoid inhalation of its dust or vapor.
Storage: It should be stored in a cool, dry, and well - ventilated place, away from flammable and combustible materials, and kept separate from reducing agents to prevent chemical reactions.
