Definition of octane in English:

octane

noun ˈɒkteɪnˈɑkteɪn

mass nounChemistry

A colourless flammable hydrocarbon of the alkane series, present in petroleum spirit.
〔化〕辛烷
Chemical formula: C₈H₁₈; many isomers, especially the straight-chain isomer (n-octane). See also isooctane
Example sentencesExamples
- To test the validity of the open-state model, molecular dynamics simulations in octane, a lipid bilayer mimetic, were carried out.
- Carbon in its most reduced form is found in alkanes, which are typically fuels like methane, propane, and octane.
- Four different solvent media were considered: octane, tetrahydrofuran, acetonitrile, and water.
- My job was to change the plastic numbers displaying the price of 87 - octane standard unleaded gasoline from $1.54 to $1.56.
- Instead, new engines have been designed to run on lower octane gasoline, which is made of hydrocarbons that are resistant to knock.

Origin

Late 19th century: from octo- 'eight' (denoting eight carbon atoms) + -ane².
