Etymology

Origin of propene

First recorded in 1865–70; prop(ionic) + -ene

Explanation

Propene is gas that occurs in nature but is used to make all kinds of unnatural plastic things like packaging and film. As a gas, propene is flammable and extremely volatile. Propene is another word for "propylene." Propene is a gas made by cracking petroleum. It’s a word that hangs out in the chemistry lab. Propene looks and sounds a lot like propane, and it’s very similar except that propene has a lower boiling point so it’s more volatile. As a gas, it’s dangerous for humans to breathe. Earthlings have been familiar with it for a while, but it was also one of the gasses found on Saturn’s moon, Titan, in 2013.
