Octane - Wikipedia
N-octane is the octane isomer that has the longest carbon skeleton. Unlike its constitutional isomers, it has a very low knock resistance. The octane isomer, iso-octane, is used as one of the standards for octane ratings. It has a rating of 100 by definition. The octane isomer 2,3,3-Trimethylpentane has an octane rating exceeding 100.
Octane | C8H18 | CID 356 - PubChem
N-octane is a colorless liquid with an odor of gasoline. Less dense than water and insoluble in water. Hence floats on water. Produces irritating vapor. Octane is a straight chain alkane composed of 8 carbon atoms. It has a role as a xenobiotic. Octane has been reported in Humulus lupulus, Aster scaber, and other organisms with data available.

2022年9月19日 · An empirical equation of state in terms of the Helmholtz energy is presented for n-octane. It is valid from the triple point temperature 216.37 K to 650 K with a maximum pressure of 1000 MPa and allows for the calculation of all thermodynamic properties in the vapor and liquid phase, in the supercritical region, and in equilibrium states.
