Method:
Copper carbonate hydroxide
Copper sulfate method; formulate the baking soda into solution of relative density of 1.05, first add to the reactor, at 50 ° C, under stirring, add refined copper sulfate solution and control the reaction temperature of 70~80 ° C. The reaction takes the change of the precipitate color to peacock green as the turning point with the pH being maintained at 8. After the stopping of the reaction, after standing and sedimentation, use 70~80 ℃ water or no ion-water to wash to until the lotion has no SO42-anymore, followed by centrifugal separation, drying to obtain the finished product of cupric carbonate base. The reaction is:
2CuSO4 + 4NaHCO3 → CuCO3 • Cu (OH) 2 + 2Na2SO4 + 3CO2 ↑ + H2O
Copper nitrate: after the electrolytic copper is reacted with concentrated nitric acid to produce copper nitrate, and then have reaction with the mixture solution of sodium carbonate and sodium bicarbonate to generate cupric carbonate basic. The precipitate is subjecting to washing, separation and dehydration, drying to yield the final products. The reaction processes are:
Cu + 4HNO3 → Cu (NO3) 2 + 2NO2 ↑ + 2H2O
2Cu (NO3) 2 + 2Na2CO3 + H2O → CuCO3 • Cu (OH) 2 + 4NaNO3 + CO2 ↑
2Cu (NO3) 2 + 4NaHCO3 → CuCO3 • Cu (OH) 2 + 4NaNO3 + 3CO2 ↑ + H2O
Chemical properties
Copper carbonate hydroxide appears as peacock green small amorphous powder. It can’t be dissolved in cold water and alcohol, being soluble in acid to form the corresponding copper salt. It is soluble in the cyanide, ammonia, ammonium salt and alkali metal carbonate aqueous solution.
