Description

Copper carbonate and cupric carbonate basic are actually not presented. The addition of sodium carbonate to the dilute copper sulfate solution, or the introduction of carbon dioxide into the suspension of copper hydroxide can both give the precipitate of cupric carbonate basic. Cupric carbonate basic can be seen as consisting of the copper hydroxide and copper carbonate. Actually there are two types of copper hydroxides with both combination with one copper carbonate and two copper carbonates

Basic copper carbonate Use and Manufacturing

Methods of Manufacturing

Copper sulfate method. Reaction equation: 2CuSO4+4NaHCO3→CuCO3·Cu(OH)2+2Na2SO4+3CO2↑+H2O Operation method: mix baking soda into a solution with a relative density of 1.05, add it to the reactor first, and add it under stirring at 50℃ Refined copper sulfate solution, the reaction temperature is controlled at 70 ~ 80 ℃, the reaction changes from precipitation to malachite green, the pH value is maintained at 8, after the reaction is allowed to stand and settle, use 70 ~ 80 ℃ water or deionized water Wash until the washing liquid is free of SO2-4, and then centrifugal separation and drying to obtain the finished basic copper carbonate. Copper nitrate method. Reaction equation: Cu+4HNO3→Cu(NO3)2+2NO2↑+2H2O2Cu(NO3)2+2Na2CO3+H2O→CuCO3·Cu(OH)2+4NaNO3+CO2↑ 2Cu(NO3)2+4NaHCO3→CuCO3·Cu( OH)2+4NaNO3+3CO2↑+H2O Operation method: after the electrolytic copper reacts with concentrated nitric acid to produce copper acid, then it reacts with the mixture of sodium carbonate and sodium bicarbonate to produce basic copper carbonate. The precipitate is washed, separated and dehydrated. After drying, the finished basic copper carbonate is obtained.

Uses

Basic copper carbonate is used in the industries of fireworks, pesticides, pigments, feed, fungicides, and antiseptics. It can also be used in electroplating, antiseptics, and analytical reagents. Specifically, Basic copper carbonate is used in agriculture as a preventive agent for plant smut, an antidote for phosphorus poisoning, and a fungicide for seeds. Basic copper carbonate mixed with asphalt can prevent livestock and wild mice from chewing on seedlings. It is also used as a copper additive in feed, as a dealkalizer when storing crude oil, and as a raw material for producing copper compounds.
