What’s the Main Difference Between Butane and Propane?

Whether you’re a homeowner or a do-it-yourselfer, you’ve probably run across the two main fuel gases: propane and butane. But you may be thinking what’s the difference between butane and propane?

These gases are both, in effect, a type of fuel. But each serves a very different and highly dependent, purpose. Keep reading for all the details you need to know about the 2 fuels.

What Propane Is

Propane is derived from natural gas processing and oil refining. It is a by-product of these processes and is not a refined fuel in and of itself. Rather, it is a liquefied petroleum gas (LPG).

Propane is colorless, odorless, and non-toxic. It is compressed and liquefied under high pressure.

Properties of Propane

Propane is a flammable gas with a boiling point of -42 degrees Celsius. It is normally a clear, colorless gas, but can appear greenish when mixed with air. It is heavier than air and can collect in low-lying areas.

It is non-toxic but can cause asphyxiation if inhaled in high concentrations.

Utilization of Propane

The most common use for propane is as a fuel for home appliances such as stoves, furnaces, water heaters, and clothes dryers. It is also popular as a recreational vehicle fuel. You can use it to power lanterns, camp stoves, and portable grills.

What Butane Is

Butane fuel comes from the refining of crude oil. The butane molecule is a hydrocarbon and is composed of carbon and hydrogen. It is a colorless, odorless gas that is highly flammable.

Properties of Butane

Butane is a colorless gas with a faint petroleum-like odor. It is highly flammable, with a boiling point of −0.5°C and a melting point of −138.3°C. When it is combusted, it produces carbon dioxide and water vapor.

Utilization of Butane

Butane fuel is mostly used as a gas for lighters and as a propellant in aerosol cans. You can use it as a fuel for some types of models and as an additive in some ways to gasoline to improve fuel economy.

In its liquid form, you can use it as a refrigerator coolant and use it to make butane hash oil. You may check the butane tank found here to see more about how you can use it.

The Differences Between the Two

In propane vs butane, butane is a liquid at room temperature, while propane is a gas. At cooler temperatures, butane becomes a gas, while propane remains a liquid. This makes butane a more efficient fuel than propane for portable stoves and lanterns because it does not need to be pressurized to remain in a liquid state.

However, propane is more commonly used in larger appliances, such as home furnaces, because it is easier to store and transport in its gaseous state.

The Similarities

Both are alkane hydrocarbons, meaning they each only contain single bonds between their carbon atoms. They are both non-polar molecules, meaning they do not have regions of high and low electrical charge that can attract or repel other molecules.

Understanding the Difference Between Butane and Propane

There may have a difference between butane and propane but there are many benefits of using them including their affordability, availability, and ease of use. They are also relatively safe to use and store, making them ideal for both home and commercial use. If you’re looking for an affordable, easy-to-use fuel source, they are great options to consider.
