, Heats, equilibrium constants, and free energies of formation of the acetylene hydrocarbons through the pentynes, to 1,500° K, J. Flame may flash back to the source of a leak very easily. ). It reacts with silver, copper and lead to form sensitive, explosive salts. Jan 14, 2026 · Explore the chemical structure of Acetylene (C2H2) and the modern industrial methods used to synthesize this essential, high-energy gas. , 1945 Wagman, D. Since acetylene is endothermic and effectively a reducing agent, its reaction with oxidants can be very violent (examples: calcium hypochlorite, nitric acid, nitrogen oxide, ozone, trifluoromethyl hypofluorite, etc. Gas is lighter than air. E. In its pure form, it is unstable and is handled as a solution. Acetylene (systematic name: ethyne) is a hydrocarbon belonging to the group of alkynes. It is widely used as a chemical building block and as a fuel. ; Pitzer, K. Jul 4, 2024 · Acetylene has a carbon-carbon triple bond (C≡C), characterized by a short length (0. D. Dec 24, 2025 · acetylene, the simplest and best-known member of the hydrocarbon series containing one or more pairs of carbon atoms linked by triple bonds, called the acetylenic series, or alkynes. Acetylene is the simplest member of the alkyne family of hydrocarbons, defined by its chemical formula $\text {C}_2\text {H}_2$. S. This colorless gas is a highly reactive compound known for its tremendous energy content, which has made it a foundational component in industrial history. ; Kilpatrick, J. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. [all data] Jul 23, 2024 · In this article, we'll explore what acetylene is, what industries it's used in, the processes it uses, its associated hazards, and the safety measures needed to work with it. This configuration makes acetylene highly unstable and reactive due to its unsaturated nature. What is Acetylene? C 2 H 2 is the simplest alkyne chemical compound with the chemical name Acetylene. Acetylene is also called Ethyne or Narcylen or Vinylene. Wagman, Kilpatrick, et al. Acetylene is not especially toxic, but when generated from calcium carbide, or CaC 2, it can contain toxic impurities such as traces of phosphine and arsine, which gives it a distinct garlic -like smell. Its unique properties and high flame temperature make it a valuable resource across industries. Acetylene is not especially toxic, but when generated from calcium carbide, or CaC 2, it can contain toxic impurities such as traces of phosphine and arsine, which gives it a distinct garlic -like smell. It is considered to be the simplest of all alkynes as it consists of two hydrogen atoms and two carbon atoms. Res. NBS, 1945, 35, 467-496. Easily ignited and burns with a sooty flame. Feb 18, 2025 · Acetylene is primarily used for welding, metal fabrication, and chemical manufacturing, though it also has various specialized applications. . 1205 nm) and high energy of formation. Description Acetylene appears as a colorless gas with a faint garlic-like odor. ; Rossini, F.
