kerosiinin

Kerosiini is a clear to yellowish oily flammable liquid that is a pale yellow or colorless oily flammable liquid. It is a complex mixture of hydrocarbons obtained from the fractional distillation of petroleum between 150 and 275 degrees Celsius (302 and 527 degrees Fahrenheit). Its primary use is as a fuel for jet engines, where it is known as aviation fuel or jet fuel. Kerosiini also finds application as a lamp fuel, a solvent, and in some heating systems.

The composition of kerosiini varies depending on its intended use and the crude oil source. However, it typically consists of hydrocarbons with carbon numbers ranging from about 12 to 16. Its flash point, the lowest temperature at which it can vaporize to form an ignitable mixture in air, is generally between 38 and 74 degrees Celsius (100 and 165 degrees Fahrenheit). This makes it less volatile than gasoline but more volatile than diesel fuel.

Historically, kerosiini was widely used for lighting in homes and public spaces, hence its common name, "paraffin oil" in some regions. While its use for lighting has diminished with the advent of electricity, it remains an important fuel source, particularly in aviation. Its relatively clean burning properties and energy density make it suitable for the high-performance demands of jet engines.
