It is used as a solvent, a chemical raw material, and an important chemical agent in the petroleum industry. Octane offers desirable blending values that achieve certain antiknock and combustion qualities for high compression engine fuels.
Octane - Energy Education
Octane is an alkane with the chemical formula C 8 H 18. As a hydrocarbon, it can be burned as a fuel. This organic molecule is a colourless liquid at room temperature with a characteristic "gasoline" odour.
3.8: Gasoline - A Deeper Look - Chemistry LibreTexts
Chemists assign octane ratings to different blends of gasoline by burning a sample of each in a test engine and comparing the observed knocking with the amount of knocking caused by specific mixtures of n-heptane and isooctane.
A Brief History of Octane in Gasoline: From Lead to Ethanol - EESI
2016年3月30日 · Octane is a gasoline additive that is needed for the proper functioning of modern engines. Octane sources have taken many forms throughout the years, both renewable and petroleum-based. They include lead, methyl tertiary butyl ether (MTBE), benzene, toluene, ethyl-benzene and xylene (BTEX), and ethanol (a biofuel).
