Propane vs. Butane: What's the Difference?
Propane, a three-carbon alkane, has a lower boiling point and is used in colder climates; butane, a four-carbon alkane, is better for warmer climates due to its higher boiling point.
Propane, a hydrocarbon gas with three carbon atoms, is commonly used as fuel in heating, cooking, and as a fuel for engines. Butane, similar in use, has four carbon atoms and is often found in lighter fuel and portable stoves. Both are alkanes and are derived from natural gas and petroleum.
The boiling point of propane is -42°C, making it vaporize at lower temperatures than butane, which has a boiling point of -2°C. This property of propane makes it more suitable for use in colder climates, while butane is preferred in warmer conditions.
Propane is stored under higher pressure compared to butane, making its containers more robust. Butane can be stored under less pressure, resulting in lighter, more easily transportable containers. This difference affects the design and use of their respective storage systems.
In terms of energy content, propane provides more energy per cubic foot than butane. This makes propane a more efficient choice for heating and cooking purposes. However, butane's higher energy content per mass makes it ideal for portable applications like lighters and camping stoves.
