What does propene mean?
Propene is the simplest alkene containing three carbon atoms, with the chemical formula C₃H₆. Its carbon–carbon double bond makes it chemically reactive and distinguishes it from propane, a saturated hydrocarbon with only single bonds. Although the gas is used chiefly as an industrial feedstock rather than as a consumer substance, propene is important in producing polypropylene, plastics, and several chemical intermediates. It is also called propylene, and that name is especially frequent in commercial and polymer-industry contexts. In scientific writing, propene is the preferred systematic name, whereas propylene remains standard terminology in industrial chemistry. Both names refer to the same compound, whose unsaturated structure allows it to take part in addition reactions and polymerisation. Understanding propene is therefore useful for anyone studying organic chemistry, plastics production, or the relationship between molecular structure and chemical behaviour.
nounPropene is a colourless, gaseous hydrocarbon with the formula C₃H₆. It is an alkene whose structure consists of a three-carbon chain containing a carbon–carbon double bond.
- A colourless gaseous hydrocarbon, C₃H₆, belonging to the alkene class and used chiefly as an industrial feedstock.
"Propene is an important feedstock in the production of polypropylene and other industrial chemicals."
"The cracking of hydrocarbons produces propene, which is then used to manufacture polypropylene."
"The researcher measured propene concentration in the reactor throughout the chemical process."
Propene has a double bond that makes it far more reactive than propane—and useful for building plastics such as polypropylene.

Where does propene come from?
The name was formed within modern systematic chemical nomenclature: prop- identifies the three-carbon parent structure associated with propane, while -ene identifies a hydrocarbon containing a carbon–carbon double bond. Related chemical names such as propionic, propanal, and propanol share the same prop- element. The modern name developed alongside the expanding use of structural nomenclature in the 19th and 20th centuries.
How propene is actually used
In technical and commercial contexts, propene is often called propylene. In British usage, the traditional spelling “propene” is especially common, although propylene is also used.
