Heptane
Heptane or n-heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16, and is one of the main components of gasoline (petrol). When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
Septane
(chemistry) heptane
Heptane
Any of several isomeric, volatile, colorless, highly flammable liquid hydrocarbons, C7H16, obtained in the fractional distillation of petroleum and used as solvents. The straight-chain isomer is also used as a standard in determining octane ratings and as an anesthetic.
Septane
See Heptane.
Heptane
(organic compound) Any of the nine isomers of the saturated aliphatic hydrocarbon C7H16, obtained from petroleum, especially n-heptane (CH3(CH2)5CH3)

Heptane
Any one of several isometric hydrocarbons, C7H16, of the paraffin series (nine are possible, four are known); - so called because the molecule has seven carbon atoms. Specifically, a colorless liquid, found as a constituent of petroleum, in the tar oil of cannel coal, etc.
Heptane
A colorless volatile highly flammable liquid obtained from petroleum and used as an anesthetic or a solvent or in determining octane ratings
