Abstract: The low-temperature oxidation of n-heptane, one of the reference species for the octane rating of gasoline, was investigated using a jet-stirred reactor and two methods of analysis: gas chromatography and synchrotron vacuum ultra-violet photo-ionization mass spectrometry (SVUV-PIMS) with direct sampling through a molecular jet. The second method allowed the identification of products, such as molecules with hydroperoxy functions, which are not stable enough to be detected using gas chromatography. Mole fractio… Show more

“…Also, while the major stable species emerging in the ignition region are CO and H 2 , the cool flame regime is characterized by significant production of a large variety of species, such as CH 2 O, H 2 O 2 , C 2 H 4 , C 3 H 6 , and so forth. The above findings are also in agreement with recent experimental evidence [28]. The prevailing kinetic mechanisms governing the oxidative reactions of n-heptane are continuously changing depending on the temperature of the mixture; this remark is clearly elucidated by comparing predictions of the production rate per unit volume for various important stable (CH 2 O, CO) and radical (HO 2 , OH) species, which are depicted in Figure 9.…”

“…The latter mechanism is capable of thoroughly describing the cool flame regime, by utilizing 25 reaction classes of the characteristic species formed under such conditions (alkylperoxy, hydroperoxy-alkyl and hydroperoxy-alkyl-peroxy radicals, cyclic ethers, carbonyl species, ketohydroperoxydes, and so on). The mechanism has been extensively validated under a variety of reactor types (e.g., plug flow reactor, jet-stirred reactors, shock tubes, and rapid compression machines) [21,27] and operational conditions (e.g., low-temperature cool flames and high pressure ignition) [21,27,28]. Additional validation relevant to the present work has been already shown in [24], while the mechanism has been also shown to be capable of accurately describing the most recent relevant experimental data [27].…”

“…Typically, these studies provide mole fractions of reactants, intermediates and products measured at the outlet of the reactor as a function of different parameters such as temperature, pressure, residence time or inlet gas composition, which can then be used to guide 7 the development and to validate combustion chemistry models. 53 For the identification and quantification of the molecular components, the JSR systems are predominantly coupled to gas chromatographs but cavity-ringdown spectroscopy, [54][55][56][57] infrared spectroscopy, 58 and mass spectrometry 18,[59][60][61][62][63][64][65] have also been applied to analyze the gas mixture. Especially when combined with molecular-beam sampling, mass spectrometry provides a powerful analytical tool for studying the composition of many gas-phase reaction systems as it allows for simultaneous detection of virtually all species, including radicals, without prior knowledge of their chemical identity.…”
