Butane is a colorless gas with a faint petroleum-like odor. For transportation it may be stenched. It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite.
What is butane? Butane is a hydrocarbon and a highly flammable, colourless, odourless, easily liquefied gas. It is typically used as fuel for cigarette lighters and portable stoves, a propellant in aerosols, a heating fuel, a refrigerant, and in the manufacture of a wide range of products. Butane is also found in Liquefied Petroleum Gas (LPG). Since 1987, hydrocarbons have replaced chlorofluorocarbons (CFCs) as the propellant used in most aerosols. Butane is one of the commonly used propellants in household and industrial aerosols and therefore can be found in numerous aerosol products. However, the packaging of many aerosols products will commonly identify the propellant as âhydrocarbonâ, not specifically identifying butane.
