Question

what is the chemical formula of kerosene

Answer 1

Kerosene is a mixture of hydrocarbons with number of carbon atoms ranging from 6 till 16. It is obtained by the fractional distillation of petroleum between 150 °C and 275 °C with a density between 0.78–0.81 g/cm3.

It is a mixture containing molecules having anywhere between 6 and 16 carbon atoms per molecule. Depending on the sulfur content, the ASTM (American Society for Testing of Materials) has recognized 2 grades of Kerosene: 1-K ( <0.04% Sulfur by weight) and 2-K (0.3% Sulfur by weight).

The majority of Kerosene is made up of straight chain alkanes and cycloalkanes (naphthenes). Alkylbenzenes and alkylnaphalenese also present although not more than 25% by volume. A small amount of olefins are also present.

Since Kerosene is a mixture of hydrocarbons, a single chemical formula with a defined number of carbon and hydrogen atoms is rather to conceive.

A rather general way of representing it would be CxHy where x can range from 6 to 16. and y depends on whether it is an alkane or cycloalkane, or another compound.

Cheers!
