Physical property


Character:The peacock green tiny amorphous powderInsoluble in water and alcohol. Soluble in acid, ammonia and potassium cyanide solution.

  1. Stable at room temperature under normal pressure

  2. Avoid material acid.Insoluble in cold water and alcohol, decomposition in the hot water, soluble in acid and copper salt accordingly.Soluble in cyanide and ammonia, ammonium salt and alkali metal carbonate in aqueous solution, forming the complex of copper.Boil in alkali metal carbonate solution, the formation of brown copper oxide.The hydrogen sulfide instability.Heated to 200 ℃ decomposition black copper oxide, carbon dioxide and water.Instability in the hydrogen sulfide gas.In the water solubility of 0.0008%.Copper carbonate dust resistance, should avoid contact with skin and eyes and inhalation.

  3. Insoluble in water, soluble in ammonia water generated in the copper ammonia complex ion.Decompose when heated to 220 ℃.Composition is 2:1 alkali type copper carbonate crystallization for sky blue powder.If long placed in the air, moisture absorption and release of carbon dioxide, slowly become a 1:1 alkali type copper carbonate, insoluble in water, but soluble in ammonia water to form a copper ammonia complex ion.

Preparation

1. Copper sulfate method. Reaction equation:

2CuSO4+4NaHCO3==CuCO3·Cu(OH)2↓+2Na2SO4+3CO2↑+H2O

2. Copper nitrate method.Methods: electrolytic copper and nitric acid generated after copper nitrate, reacts with sodium carbonate and sodium bicarbonate mixture generated alkali type copper carbonate, precipitation after washing, separation, dehydration, drying, alkali type copper carbonate was finished.

3. Copper nitrate and sodium carbonate as raw material, the preparation of amount of substance such as trihydrate copper nitrate and sodium carbonate solution, mixing, stirring, at this point that generate blue-green colloidal precipitation, continue stirring at room temperature, the crystal material can generate, filtration, drying in the air. Composition for the product can be got.

Or can also be used for five copper sulfate hydrate or a hydrated copper acetic acid and potassium carbonate as raw material was also the purpose of the product.

Application

1.Used in organic catalysts, fireworks, and pigments. Role in agricultural plants smut preventing agent, phosphorus pesticides and poison the antidote, mixed with asphalt can prevent the chip and rats chew saplings; Used in feed for copper additive, as dealkalization agent in oil storage and production of copper compound materials. Can also be used in electroplating, antisepsis and analytical reagent.

2. Used as feed additives, cattle and other ruminants of copper carbonate absorption utilization rate is higher than other inorganic copper. But due to the high cost, make its application is limited.

3. Used as analytical reagent. Used for copper salt preparation, preparation of paint pigments and fireworks raw materials. As an activator phosphors, seed fungicides.

4. To a copper alloy, silver plated copper tin alloy and the confecting of oxidation of steel.

Storage and transportation

1. Store in a cool, ventilated, dry warehouse.

2. We should pay attention to moistureproof. Bags against breakage.
