Production Process of Basic Copper Carbonate

0 like 0 dislike

Basic Copper Carbonate (WSDTY) and copper hydrogencarbonate are not actually present. Precipitation of basic copper carbonate can be obtained by adding sodium carbonate to a dilute copper sulfate solution or by passing carbon dioxide into a copper hydroxide suspension. Basic copper carbonate can be regarded as composed of copper hydroxide and copper carbonate. Actually, there are two kinds of copper hydroxide, copper carbonate and copper hydroxide.

The former chemical formula is CuCO3·Cu(OH)2, which is a grass-green monoclinic crystalline fibrous group or a dark green powder. The precipitate obtained from the solution initially appeared green, and after leaving it turned dark green in the solution. It is toxic and is the main component of green rust (commonly known as patina) produced on the copper surface.

The latter chemical formula is 2CuCO3·Cu(OH)2, deep sky blue, very bright monoclinic crystals, or tightly crystalline lumps. It is insoluble in water, soluble in ammonia and hot and concentrated sodium bicarbonate solution to form a blue color, which decomposes at 300 °C.

Basic copper carbonate can be used in the manufacture of signal flares, pyrotechnics, paint pigments, other copper salts, solid phosphor activators, insecticides, seed treatments and as fungicides and antidotes, as well as in electroplating.
