Quick Summary

Methylacetylene, also known as allylene, is a gaseous hydrocarbon with the chemical formula CH₃C≡CH. It has an unpleasant smell and burns with a smoky flame. Methylacetylene is a type of alkyne, which are hydrocarbons containing a carbon-carbon triple bond. The simplest alkyne is acetylene (C₂H₂), a colorless, flammable gas widely used in welding and as a chemical precursor. While pure acetylene has a pleasant odor, impurities can give it an unpleasant smell. Acetylene is highly reactive and can form explosive mixtures with air.123

and, possibly, propane and methyl acetylene. All of the latter may be produced by photochemical effects (see photochemical reaction) from solar ultraviolet radiation or, at higher latitudes, by energetic electrons precipitating from Saturn’s radiation belts (see below The magnetic field and magnetosphere).
