Structure
The fuel used in
lighters is mainly flammable gas. Gasoline was mostly used in the early days, but it is now rarely used because of its peculiar smell. Butane, propane and liquefied petroleum gas are mostly used. They are pressurized and filled into a closed air box. Once released into the air, they will absorb heat and vaporize and expand rapidly, 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 with the same molecular formula (C4H10). Includes: n-butane and isobutane (2-methylpropane). Butane is a flammable, colorless, easily liquefied gas. It is an important raw material for the development of petrochemical and organic raw materials, and its use has been paid more and more attention.
Performance
Colorless flammable gas. Melting point -135.35°C, boiling point -0.5°C, relative density 0.5730 (25°C), refractive index 1.3326 (20°C), critical temperature 1520°C, critical pressure 380kPa, critical volume 4387ml/g. Insoluble in water, soluble in alcohol, ether, chloroform and other hydrocarbons. Forms an explosive mixture with air with an explosion limit of 19% to 84% (V/V).
