| overview | chemical formula Cu(NO3)2, white powder. Easy deliquescence, easy to dissolve in water, solubility is 45g at 0 ℃, add concentrated nitric acid, can sink again. Red hot time into nitrogen oxides and copper oxide, which are decomposed by hydrochloric acid. Common hydrates are hexahydrate Cu(NO3)2 · 6H2O and trihydrate Cu(NO3)2 · 3H2O. The former is a blue crystal with a relative density of 2.074. When the temperature is 26.4 ℃, it loses three molecules of crystal water to form trihydrate, and decomposes to form basic salt at 65 ℃. The latter is dark blue triangular crystal with 241.60 molecular weight, melting point 114.5 ℃, blue columnar crystal and density 2.32g/cm3. Easily soluble in water and ethanol, concentrated solution green, dilute solution light blue, easy deliquescence. Dissolve in its crystalline water at 114.5 ℃, lose nitric acid when heated to 170 ℃ to form basic copper nitrate, and decompose into copper oxide when heated to 200 ℃. It is oxidizing, and it is easy to explode or burn when mixed with carbon, sulfur and other substances. Used for copper plating, pesticide making, enamel and dyes. Dissolved in medium concentration nitric acid, copper nitrate can be produced by copper oxide or copper block and dilute nitric acid. |

| production method | production method Cu + 3N 2 O 4 → Cu(NO 3) 2N 2 O 4 + 2NO Cu(NO 3) 2N 2 O 4 → Cu(NO 3 ) 2 + N 2 O 4 releases 20mL N 2 O 4 from the cylinder into the reaction tube a in the figure. Then copper strips and 20mL ethyl acetate were added and left at room temperature for 4 hours. precipitated Cu(NO 3 ) 2N 2 O 4 was precipitated. the reaction tube was removed to quickly remove unreacted metal copper and 20mL N 2 O 4 was added. Reinstall the reaction tube, pump the instrument upside down, remove reaction tube A, and wash the precipitate with 15mL N 2 O 4. Remove the filtrate tube C and pour the generated Cu(NO 3 ) 2N 2 O 4 into another drying tube A. Plug a small piece of glass wool above the crystal, connect the tube to a high vacuum line, heat to 120 ℃ in an oil bath (immersed above the glass wool) at 1.33Pa, decompose the compound into anhydrous Cu(NO 3) 2, slowly heat to 200 ℃ and sublimate copper nitrate above the tube wall for collection. The refining method uses hot fuming nitric acid to recrystallize commercially available copper nitrate trihydrate to obtain anhydrous copper nitrate. When the commercially available copper nitrate trihydrate is recrystallized with about 3% dilute nitric acid, hexahydrate is precipitated under cold and trihydrate is precipitated above 30 ℃. |
