'''Propylene''', also known as '''propene''', is an [[Unsaturated compound|unsaturated]] [[organic compound]] with the [[chemical formula]] {{chem2|CH3CH\dCH2}}. It has one [[double bond]], and is the second simplest member of the [[alkene]] class of [[hydrocarbon]]s. It is a colorless gas with a faint petroleum-like odor.<ref>{{Cite web | url=https://pubchem.ncbi.nlm.nih.gov/compound/Propene#section=Top |title = Propylene}}</ref>

Propylene is a product of combustion from forest fires, cigarette smoke, and motor vehicle and aircraft exhaust.<ref name=MDPI>{{Cite journal |last=Morgott |first=David |date=2018-01-04 |title=The Human Exposure Potential from Propylene Releases to the Environment |journal=International Journal of Environmental Research and Public Health |language=en |volume=15 |issue=1 |pages=66 |doi=10.3390/ijerph15010066 |issn=1660-4601 |pmc=5800165 |pmid=29300328 |doi-access=free }}</ref> It was discovered in 1850 by [[August Wilhelm von Hofmann|A.
