Butanes are a group of hydrocarbons that consists of four carbon atoms. This group of gases is commonly used as fuel, especially for lighters and camping stoves. However, there are several synonyms that you can use instead of the word butanes. These include butane gas, n-butane, normal butane, or simply butane. Additionally, you may find the term liquefied petroleum gas (LPG) to refer to butanes or a combination of butanes and propane. This gas is widely used in household heating and cooking, as well as in the petrochemical and automotive industries. Remember, regardless of what term you use, always handle butanes and other flammable gases with caution.
