1.3 Synthetic Route
1. Copper sulfate method: the baking soda is prepared into a solution with a relative density of 1.05, first added to the reactor, at 50 °C, the refined copper sulfate solution is added under stirring, the reaction temperature is controlled at 70~80 °C, the reaction is precipitated into peacock green as the degree, the pH value is kept at 8, after the reaction is static, sedimentation, washed with 70~80 °C water or ionized water until the washing solution is SO2-4, and then centrifuged and separated, dried to obtain a basic copper carbonate product.
Copper nitrate method. Operation method: electrolytic copper and concentrated nitric acid react to generate copper chamber acid, and then react with the mixture of sodium carbonate and sodium bicarbonate to generate basic copper carbonate, and the precipitation is washed, separated, dehydrated and dried to obtain a finished basic copper carbonate product.
