Product Description
Heptane or n-heptan is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16, and is one of the main components of gasolines (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). Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctanes which is expressed as the percentage of isooctanes in heptane and is listed on pumps for gasolines (petrol) dispensed globally.
