About Copper nitrate
The copper nitrate character is Dark blue granular crystals. The density is 2.23g/cm3. Melting point 114.5 C. It is soluble in water and ethanol, and the water solution is acidic. A mixture of copper nitrate and acetic anhydride (Menke condition), named after the Dutch chemist who discovered it, is a useful nitrifier in organic synthesis and is used in the nitrification of aromatic compounds. Copper nitrate loaded onto clay (montmorillonite), known as Claycop, can be used to oxidize mercaptan to disulfide, convert thiotaldehyde to carbonyl compounds, and nitroaromatic compounds to avoid environmental contamination from heavy use of mixed acids. Can be combined with ammonia water synthesis of nitric acid tetraammonia copper (TACN, a kind of energetic material.).
Copper nitrate soluble in concentrated ammonia water, forming copper tetramine dinitrate complex, heating explosion occurs. Easy to absorb moisture, toxic!The toxic data of copper nitrate is copper salt makes person chronic when toxic, expression is nervous system function disorder, liver kidney function obstacle, nose septum ulcer forms and perforation. Acute poisoning, nausea, vomiting, abdominal pain, diarrhea, in plasma and urine soon appear hemoglobin, jaundice, anemia, red blood cell resistance. Irritating to skin; Dust can irritate the eyes and cause corneal ulcers. The maximum permissible concentration is 1 mg/m in copper.
It is a strong oxidant. Paper immersed in copper nitrate ethanol solution can spontaneously ignite dry scrap paper. When heated to 114.5 C, it decomposes and escapes nitric acid to form insoluble alkaline salts. When heated to intense burning, it transforms into copper oxide. Heating, friction or impact with carbon dust, sulphur or other combustible substances can cause combustion and explosion. Toxic and irritating nitrogen peroxide is produced during combustion. The enamel industry is used as a colouring agent. Electroplating industry is used as copper plating bath. Chemical industry is used as oxidant. In addition, it is also used in the manufacture of pesticides, dyes and so on.
