Octane
Octane/IUPAC ID
What is the chemical formula of octane?
C₈H₁₈
Octane/Formula
A straight chain alkane composed of 8 carbon atoms. Octane is a hydrocarbon and an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3.
What properties does gasoline have?
The most important properties of gasoline fuels are properties such as volatility and knocking resistance, whereas diesel fuels are required to have important fuel properties such as viscosity, surface tension, and ignition tendency.
What is octane chemistry used for?
So it is an important constituent of petrol (US:gasoline). Octane ratings are ratings used to represent the anti-knock performance of petrol by giving the percentage of octane in an octane-heptane mixture that would have the same performance.
What is the chemical structure of gasoline?
The typical composition of gasoline hydrocarbons (\% volume) is as follows: 4-8\% alkanes; 2-5\% alkenes; 25-40\% isoalkanes; 3-7\% cycloalkanes; l-4\% cycloalkenes; and 20-50\% total aromatics (0.5-2.5\% benzene) (IARC 1989).
What is the chemical octane used for?
The higher the octane number, the more resistant the gasoline mixture is to knock. The use of higher octane fuels also enables higher compression ratios, turbocharging, and downsizing/downspeeding—all of which enable greater engine efficiencies and higher performance.
What type of bond is octane?
Octane belongs to a family of molecules called alkanes. These are hydrocarbon molecules with just single, two-electron, bonds connecting the atoms. There is a whole series of them with increasing numbers of carbon atoms, starting from methane (1 carbon), ethane (2 carbons), propane (3), butane (4), etc.
What are the chemicals in gasoline?
Gasoline is a mixture of many different hydrogen- and carbon- containing chemicals (hydrocarbons). A typical gasoline mixture contains about 150 different hydrocarbons, including butane, pentane, isopentane and the BTEX compounds (benzene, ethylbenzene, toluene, and xylenes).
What is gasoline chemistry?
Gasoline is a petroleum-derived product comprising a mixture of liquid aliphatic and aromatic hydrocarbons, ranging between C4 and C12 carbon atoms with the boiling range of 30–225°C. It is predominantly a mixture of paraffins, naphthenes, aromatics and olefins. From: TrAC Trends in Analytical Chemistry, 2017.
Is octane an element compound or mixture?
Octane is an eight carbon aliphatic compound that is a natural constituent of the major paraffin fraction of crude oil and also found in natural gas. A total of 17 isomers of octane are known to exist and differ by the amount and location of branching in the carbon chain.
What kind of organic compound is octane?
alkane
Octane is an organic chemical, specifically an alkane, with formula C8H18. (8 carbon alkene).
What are chemical properties does Octane have?
Some important chemical facts about this compound are as follows: Chemical formula = C 16 H 34 Molar mass = 226.45 g/mol Melting point = 18 °C Boiling point = 287°C Appearance = colorless liquid Odor = gasoline-like odor
What is the structural formula for Octane?
Octane. Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. 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…
What is the chemical equation for Octane?
