Kerosene is a clear, hydrocarbon liquid commonly used as a fuel in various applications such as jet engines, lamps, heaters, and as a solvent. It is derived from petroleum through a refining process known as distillation. Chemically, kerosene is a mix of carbon chains, typically containing 12 to 15 carbon atoms per molecule.
The scent profile of kerosene is quite distinctive and robust. It has a strong, pungent odor that is somewhat oily and can be slightly sweet. The smell is often described as "petroleum-like" due to its origin from crude oil. This odor is characteristic of many hydrocarbon solvents, often perceived as sharp and penetrating. When burned, kerosene's smell may become slightly more acrid and sooty, especially if the combustion process is incomplete. The intensity of its scent can vary based on its purity and the presence of additional refined compounds. Some people might find the smell of kerosene unpleasant and overpowering, while others are more accustomed to it, particularly in areas where it is commonly used as a household fuel.
