Carbon compounds,
Compounds of carbon (Chem.), those compounds consisting largely of carbon, commonly produced by animals and plants, and hence called organic compounds, though their synthesis may be effected in many cases in the laboratory. [ 1913 Webster ] The formation of the compounds of carbon is not dependent upon the life process. I. Remsen --
carbon copy, originally, a copy of a document made by use of a carbon paper, but now used generally to refer to any copy of a document made by a mechanical process, such as xerographic copying. --
Carbon dioxide,
Carbon monoxide. (Chem.) See under Carbonic. --

Carbon point (Elec.), a small cylinder or bit of gas carbon moved forward by clockwork so that, as it is burned away by the electric current, it shall constantly maintain its proper relation to the opposing point. --
Carbon paper, a thin type of paper coated with a dark-colored waxy substance which can be transferred to another sheet of paper underneath it by pressing on the carbon paper. It is used by placing a sheet between two sheets of ordinary writing paper, and then writing or typing on the top sheet, by which process a copy of the writing or typing is transferred to the second sheet below, making a copy without the need for writing or typing a second time. Multiple sheets may be used, with a carbon paper placed above each plain paper to which an impression is to be transferred. In 1997 such paper was still used, particularly to make multiple copies of filled-in purchase invoice forms, but in most applications this technique has been superseded by the more faithful xerographic reproduction and computerized printing processes. --

Carbonic acid (Chem.), an acid HO.CO.OH, not existing separately, which, combined with positive or basic atoms or radicals, forms carbonates. In common language the term is very generally applied to a compound of carbon and oxygen, CO2, more correctly called carbon dioxide. It is a colorless, heavy, irrespirable gas, extinguishing flame, and when breathed destroys life. It can be reduced to a liquid and solid form by intense pressure. It is produced in the fermentation of liquors, and by the combustion and decomposition of organic substances, or other substances containing carbon. It is formed in the explosion of fire damp in mines, and is hence called after damp; it is also know as choke damp, and mephitic air. Water will absorb its own volume of it, and more than this under pressure, and in this state becomes the common soda water of the shops, and the carbonated water of natural springs. Combined with lime it constitutes limestone, or common marble and chalk. Plants imbibe it for their nutrition and growth, the carbon being retained and the oxygen given out. --
Carbonic oxide (Chem.), a colorless gas, CO, of a light odor, called more correctly carbon monoxide. It is almost the only definitely known compound in which carbon seems to be divalent. It is a product of the incomplete combustion of carbon, and is an abundant constituent of water gas. It is fatal to animal life, extinguishes combustion, and burns with a pale blue flame, forming carbon dioxide. [ 1913 Webster ]

If the process stops here it is called single transfer; if the image is afterward transferred in order to give an unreversed print, the method is called double transfer. [ Webster 1913 Suppl. ]

Carbonyl chloride (Chem.), a colorless gas, COCl2, of offensive odor, and easily condensable to liquid. It is formed from chlorine and carbon monoxide, under the influence of light, and hence has been called phosgene, or phosgene gas; -- called also carbon oxychloride.
