| Hazard Information | Back Directory | 【General Description】
Reddish lustrous malleable odorless metallic solid. | 【Reactivity Profile】
COPPER(7440-50-8) combines violently with chlorine trifluoride in the presence of carbon [Mellor 2, Supp. 1, 1956]. Is oxidized by sodium peroxide with incandescence [Mellor 2:490-93, 1946-1947]. Forms an unstable acetylide when acetylene is passed over samples that have been heated enough to form an oxide coating. Reacts more rapidly in powdered or granular form. Subject to explosive reaction then mixed in finely divided form with finely divided bromates chlorates and iodates of barium, calcium, magnesium, potassium, sodium, or zinc; these reactions are initiated by heat, percussion, and occasionally light friction [Mellor 2:310, 1946-1947]. A solution of sodium azide in COPPER(7440-50-8) pipe with lead joints formed COPPER(7440-50-8) azide and lead azide, both of these compounds can detonate [Klotz, 1973]. | 【Air & Water Reactions】
Solid pieces are very slowly oxidized by air to give a green basic carbonate. Solid pieces become covered by a black oxide when heated in air. Insoluble in water. |
