How To Draw The Constitutional or Structural Isomers of C8H18 - Octane

Molecular Libraries Screening Center Network. Natural Products. NIH Substance Repository.Octane has many structural isomers that differ by the amount and location of branching in the carbon chain.

One of these isomers, 2,2,4-trimethylpentane isooctane is used as one of the standard values in the octane rating scale. Octane is a component of gasoline petrol. As with all low-molecular-weight hydrocarbons, octane is volatile and very flammable. The octane rating was originally determined by mixing a gasoline made entirely of heptane and 2,2,4-trimethylpentane a highly branched octaneand assigning anti-knock ratings of 0 for pure heptane and for pure 2,2,4-trimethylpentane.

The anti-knock rating of this mixture would be the same as the percentage of 2,2,4-trimethylpentane in the mix. Different isomers of octane can contribute to a higher or lower octane rating. For example, n -octane the straight chain of 8 carbon atoms with no branching has a negative octane rating, while pure 2,2,4-trimethylpentane a highly branched octane has an octane rating of Octane became well known in American popular culture in the mid- and late s, when gasoline companies boasted of "high octane" levels in their gasoline advertisements.

The compound adjective "high-octane", meaning powerful or dynamic, is recorded in a figurative sense from Octane has 18 structural isomers 24 including stereoisomers :. From Wikipedia, the free encyclopedia.

For the gasoline rating system, see octane rating. For other uses, see Octane disambiguation.

Asked in Chemistry, Elements and Compounds What is the molecular formula for octane? The molecular formula for octane straight chain is C8H Asked in Chemistry, Organic Chemistry How many molecules are in octane? The chemical formula of octane is C8H18 - and this is the molecule of octane!

Asked in Hydrocarbons Is octane an alkane? Octane is an alkane and has the formula C8H Asked in Organic Chemistry What is its empirical formula isooctane? Octane and iso-octane both have the molecular formula C8H18, so empirical formula is C4H9. Octane is an alkane hydrocarbon with the chemical formula C8HIt is one of several isomers of octane C 8 H This particular isomer is the standard point on the octane rating scale the zero point is n -heptane.

It is an important component of gasolinefrequently used in relatively large proportions to increase the knock resistance of the fuel. However, 2,2,4-trimethylpentane is by far the most important isomer of octane and so, historically, it has been assigned this name.

Isooctane is produced on a massive scale in the petroleum industry by alkylation of isobutene with isobutane. The process is conducted in alkylation units in the presence of acid catalysts.

It can also be produced from isobutylene by dimerization using an Amberlyst catalyst to produce a mixture of iso-octenes. Hydrogenation of this mixture produces 2,2,4-trimethylpentane.

Engine knocking is an unwanted process that can occur during high compression ratios in internal combustion engines. Graham Edgar in added different amounts of n -heptane and 2,2,4-trimethylpentane to gasoline, and discovered that the knocking stopped when 2,2,4-trimethylpentane was added.

This work was the origin of the octane rating scale. The same test motors, run in the same fashion, using heptane, gave a performance which was standardized as 0 octane. All other compounds and blends of compounds then were graded against these two standards and assigned octane numbers. In common with all hydrocarbons, 2,2,4-trimethylpentane is flammable.

Asked in Elements and Compounds What is the condensed structural formula of hexyl acetate?The alkene is classified as a higher olefin and alpha-olefinmeaning that the double bond is located at the alpha primary position, endowing this compound with higher reactivity and thus useful chemical properties.

It is a colourless liquid. In industry, 1-octene is commonly manufactured by two main routes: oligomerization of ethylene and by Fischer—Tropsch synthesis followed by purification. Another route to 1-octene that has been used commercially on a small scale is dehydration of alcohols. There are five commercial processes that oligomerize ethylene to 1-octene. Four of these processes produce 1-octene as a part of a wide distribution of alpha-olefins. The only commercial process to isolate 1-octene from a wide mixture of C 8 hydrocarbons is practiced by Sasola South African oil and gas and petrochemical company.

In recent years, two on-purpose 1-octene technologies have been commercialised: a butadiene telomerization plant Dow, Tarragonaand a 1-heptene to 1-octene plant based on a Fischer-Tropsch-derived C 7 olefin stream Sasol, Secunda.

Sasol is currently in the engineering phase of a new 1-octene technology based on selective tetramerisation of ethylene. The main use of 1-octene is as a comonomer in production of polyethylene. Another significant use of 1-octene is for production of linear aldehyde via oxo synthesis hydroformylation to give the C9 aldehyde nonanal.

Oxidation of this aldehyde gives the short-chain fatty acid nonanoic acid. Hydrogenation of the same aldehyde gives the fatty alcohol 1-nonanolwhich is used as a plasticizer. From Wikipedia, the free encyclopedia.

The conformation of cyclooctane has been studied extensively using computational methods. Hendrickson noted that "cyclooctane is unquestionably the conformationally most complex cycloalkane owing to the existence of many conformers of comparable energy. Among the many compounds exhibiting the crown conformation structure II is S 8elemental sulfur. The main route to cyclooctane derivatives involves the dimerization of butadienecatalysed by nickel 0 complexes such as nickel bis cyclooctadiene.

COD is widely used for the preparation of precatalysts for homogeneous catalysis. The activation of these catalysts under H 2produces cyclooctane, which is usually discarded or burnt:. Cyclooctane participates in no reactions except those typical of other saturated hydrocarbons, combustion and free radical halogenation.

Work in on alkane functionalisation, using peroxides such as dicumyl peroxide, has opened up the chemistry to some extent, allowing for example the introduction of a phenylamino group.
