Oxidation of n-heptane and 2,2,4-trimethylpentane i-octane

Although there had been earlier attention [201], towards the end of the 1980s interests became focused more strongly on the study of the behaviour of the primary reference fuels for gasoline (petrol), i.e., n-heptane and i- 

Non-isothermal combustion of stoichiometric fuel air mixtures (4 = 1) has been studied by Lignola et al. [32,133], and isothermal oxidation has been studied by Dagaut et al. [30, 202]. Chemical measurements have been made during the oxidation of n-heptane, or i-octane, at pressures up to 1.2 and 1.0 MPa and at temperatures in the range 570-840 K and 550-1150 K, respectively. 

Components that were identified by Lignola et al. [32], by use of GC-MS, during stationary state combustion of both n-heptane and i-octane in air at = 1 are shown in Table 6.11. Greater extents of reaction of i- 

Typical molecular products of n-heptane and i-octane oxidation over the temperature range 550-1200 K at 1.0 MPa in a jet-stirred flow reactor. The components are listed according to their maximum mole fractions of products below, above or in the vicinity of 850 K [31]
