Meaning and Definition
A colourless, flammable gas that is a hydrocarbon with three carbon atoms and one double bond (C3H6), used primarily in the industrial production of plastics, chemicals, and fuels.
It is an important petrochemical feedstock and an alkene, often a byproduct of oil refining and natural gas processing. It is also known as propene.
Dialectal Variation

FAQ
Frequently Asked Questions
No. Propane (C3H8) is a saturated alkane used as fuel. Propylene (C3H6) is an unsaturated alkene used primarily as a chemical feedstock. They have different chemical structures and uses.
Directly, no, as it's a flammable gas handled industrially. Indirectly, yes, as it's a key raw material for polypropylene plastic found in food containers, textiles, and automotive parts.
Propylene (or propene) is the basic chemical molecule (monomer). Polypropylene is the long-chain polymer plastic made by linking many propylene molecules together.
It is one of the most important petrochemicals globally, serving as the starting point for a vast array of products including plastics (e.g., packaging, fibres), chemicals (e.g., propylene oxide for foams), and solvents.

Mnemonic
Think 'PROPeller' made from PLASTIC. PROPyLENE is a gas used to make plastics like polypropylene. The 'ene' rhymes with 'keen' and means it's an unsaturated hydrocarbon.
Conceptual Metaphor
Raw material / Building block (e.g., 'Propylene is a fundamental building block for the plastics industry.')
