What is butane?
Getting to know the gas better

What exactly is butane?

We know butane very well and we’re here to help you get to know the gas a little better

Butane (C₄H₁₀), like propane, is a form of LPG (Liquefied Petroleum Gas). With its boiling point at -2°C, butane is ideal for fuelling portable gas heaters and indoor use. Under natural atmospheric conditions, butane takes the form of a gas. However, in order to be stored, it needs to be liquefied, which can be achieved under moderate pressure.

If you'd like to know the differences between butane and propane or how butane fuels an appliance – take a look at our LPG page.
