The fuel used in lighters is mainly flammable gases. Gasoline used in the early days is rarely used because of its odor. Butane, propane and petroleum liquefied gases are now used. They are pressurized and filled into a closed air box. Once released into the air, they are heated and vaporized and rapidly expand, making them easy to ignite. The butane (CH3-CH2-CH2-CH3) used in the lighter is n-butane, which is a general term for two alkane hydrocarbons having the same molecular formula (C4H10). These include: n-butane and isobutane (2-methylpropane). Butane is a flammable, colorless, easily liquefied gas. It is an important raw material for the development of petrochemicals and organic raw materials, and its use is receiving increasing attention.
