WebSep 4, 2024 · The octane rating was originally determined by mixing fuels from only heptane and 2,2,4-trimethylpentane (a highly branched octane), and assigning anti-knock ratings of zero for pure heptane and 100 for pure 2,2,4-trimethylpentane. The anti-knock rating of this mixture would be the same as the percentage of the latter in the mix. 2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH3)3CCH2CH(CH3)2. It is one of several isomers of octane (C8H18). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane).

WebThe octane number of a fuel is measured in a test engine against a mixture of iso-octane and heptane. If a gasoline sample has the same antiknock quality as that of a mixture containing 90% isooctane and 10% heptane, then the octane number for that sample is defined as 90. Some hydrocarbons have higher anti-knocking capacity than iso-octane. WebDimerization of linear olefins represents an attractive route for the production of high octane number blending components. The oligomerization needs not only to be high conversion and to produce mainly dimers but also to be selective within the dimer range, as only certain isomers have advantageous blending octane numbers.
