acetylenes, plural;
  1. A colorless pungent-smelling hydrocarbon gas, which burns with a bright flame, used in welding and formerly in lighting

  1. a colorless flammable gas used chiefly in welding and in organic synthesis
  2. Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in pure form and thus is usually handled as a solution.
  3. Acetylene is a 2005 album by The Walkabouts.
  4. (Acetylenes) Alkynes are hydrocarbons that have a triple bond between two carbon atoms, with the formula CnH2n-2. Alkynes are traditionally known as acetylenes, although the name acetylene also refers specifically to C2H2, known formally as ethyne using IUPAC nomenclature. ...
  5. Any organic compound having one or more carbon–carbon triple bonds; an alkyne; Ethyne; the simplest alkyne, a hydrocarbon of formula HC≡CH. It is a colourless gas, with a peculiar, unpleasant odour, formerly used as an illuminating gas, but now used in welding or metallurgy
  6. A highly combustible gas composed of carbon and hydrogen. Used as a fuel gas in the oxyacetylene welding process.
  7. is prepared industrially by cracking and dehydrogenation of hydrocarbons as described for ethylene (see above Alkanes: Chemical reactions). Temperatures of about 800 °C (1,500 °F) produce ethylene; temperatures of roughly 1,150 °C (2,100 °F) yield acetylene. ...
  8. A gas produced by the action of water upon calcium chloride. This gas combined with oxygen burns with a very hot flame.
  9. a hydrocarbon gas (C2H2) used as a fuel
  10. A pure gas compound (HC2H) mostly made by man and supplied in tanks for use as fuel for a very high temperature (4000F) flame for welding and metal cutting. Dangerous in that it is explosive over a wide range of air/gas mixtures. 2009-07-26
  11. Highly flammable, gaseous, hydrocarbon used in combination with oxygen as the fuel source in Oxy-Acetylene gas torch welding.
