Acetylene

From GAWDAwiki

Jump to: navigation, search

Acetylene is a highly combustible gas composed of carbon and hydrogen. It is used as a fuel gas in the oxyacetylene welding process.[1]

An alternate definition is a fuel gas comprising two carbon atoms and two hydrogen atoms, C2H2. If acetylene is compressed on its own, it can lead to a highly exothermic reaction. For this reason, acetylene is supplied dissolved in acetone. Acetylene cylinders are made of a porous material capable of storing the acetone-acetylene solution.[2]

Acetylene is the most common gas used for fueling cutting torches in both general industry and the mining industry. When mixed with pure oxygen in a cutting torch assembly, an acetylene flame can theoretically reach over 5700°F. Users of this type of equipment are generally familiar with the fire hazards associated hot flames and the production of hot slag.[3]

Acetylene is sometimes also known as ethyne.[4]
