Decane is a straight-chain alkane hydrocarbon with the chemical formula \(C_{10}H_{22}\). While 75 structural isomers are theoretically possible, the term "decane" typically refers to the normal, unbranched form, n-decane, which is. It is a colorless, flammable liquid with a gasoline-like odor in high concentrations. Like other alkanes, it is nonpolar and thus insoluble in water, but readily dissolves in other organic solvents. Decane is found in small quantities in gasoline and kerosene and is also used as a solvent in industries such as paint, varnish, and rubber manufacturing. Additionally, it serves as a component in diesel fuel, improving its combustion properties and reducing emissions due to its high cetane number.
