Description
A colorless hydrocarbon gas with an ether-like odor. Acetylene was used for theater lighting prior to electric lights because it burned brightly giving off over 10 times more illumination than other gases. When mixed with oxygen, the oxyacetylene fuel burns with an intensely hot flame that is used for welding, cutting, and soldering metals. Acetylene is also used to synthesize polymeric precursors such as vinyl chloride, vinylidene chloride, vinyl acetate, and acrylates.
Synonyms and Related Terms
ethyne; ethine; gaseous carbon; acetileno (Port.);
Other Properties
Soluble in water, ethanol and acetone. It is often sold dissolved in acetone in order to make it non-explosive.
