- noun A colorless gas, C2H2, which has a characteristic and very unpleasant odor, and burns with a luminous smoky flame.
- noun This gas, C2H2, prepared by the action of water on calcium carbide, is now largely used as an illuminant and to increase the illuminating value of coal-gas and water-gas of poor quality.

- noun (Chem.) A gaseous compound of carbon and hydrogen, in the proportion of two atoms of the former to two of the latter. It is a colorless gas, with a peculiar, unpleasant odor, and is produced for use as an illuminating gas in a number of ways, but chiefly by the action of water on calcium carbide. Its light is very brilliant.

When those two substances are mixed together the hydrogen of the water leaves its original partner, oxygen, and the carbon of the calcium carbide leaves the calcium, uniting together to form that particular compound of hydrogen and carbon, or hydrocarbon, which is known as acetylene, whose formula is C_2H_2; while the residual calcium and oxygen join together to produce calcium oxide or lime, CaO.
