Etymology

Origin of propane

First recorded in 1866; prop(ionic) + -ane

Explanation

Propane is a flammable fuel you can use to heat your house, barbecue, or portable camping stove. Propane is refined from natural gas and petroleum. Propane is a gaseous hydrocarbon that is stored as a liquid under pressure in tanks. Propane is as useful as it is volatile. It's useful because it's a portable fuel that you can heat anything from a small stove to an entire house with. But propane is dangerous because it's highly flammable. That’s why houses heated by propane have propane tanks outside. Propane must be stored and handled carefully and away from flames.
