We are selling any kind of Kerosene is a thin, clear liquid
formed from hydrocarbons obtained from the fractional distillation
of petroleum between **0 °C and **5 °C, resulting in a mixture with
a density of 0.**0.*1 g/cm3 composed of carbon chains that
typically contain between 6 and *6 carbon atoms per molecule.
It is miscible in petroleum solvents but immiscible in water. The
American Society for Testing and Materials standard specification
D*******8 recognizes two grades of kerosene: grades *-K (less than
0.*4% sulfur by weight) and *-K (0.3% sulfur by weight). *-K grade
kerosene burns cleaner with fewer deposits, fewer toxins, and less
frequent maintenance than *-K grade kerosene, and is the preferred
grade of kerosene for indoor kerosene heaters and stoves.
Regardless of crude oil source or processing history, kerosene's
major components are branched and straight chain alkanes and
naphthenes (cycloalkanes), which normally account for at least *0%
by volume. Aromatic hydrocarbons in this boiling range, such as
alkylbenzenes (single ring) and alkylnaphthalenes (double ring), do
not normally exceed *5% by volume of kerosene streams. Olefins are
usually not present at more than 5% by volume.
The flash point of kerosene is between *7 and *5 °C (**0 and **0
°F), and its autoignition temperature is **0 °C (**8 °F).[*1] The
pour point of kerosene depends on grade, with commercial aviation
fuel standardized at −*7 °C (−*3 °F). *-K grade kerosene freezes
around **0 °C (**0 °F, **3 K)
