  Methylene (singlet) formed by the photolysis of ketene (313 nm) reacts with oxetan to yield 2-methyl- and 3-methyloxetans by insertion in the C—H bonds and probably also tetrahydrofuran. These products are formed chemically activated and undergo unimolecular decomposition unless collisionally stabilized. Using perfluoropropane as the bath gas, the results obtained with 2-methyloxetan have been interpreted

  通过乙烯酮（313 nm）的光解反应形成的亚甲基（单体）与氧杂环丁烷发生反应，通过插入CH键以及可能还会插入四氢呋喃而生成2-甲基和3-甲基氧杂环丁烷。这些产物是化学活化形成的，除非发生碰撞稳定，否则会发生单分子分解。使用全氟丙烷作为熔池气体，使用RRKM理论和阶梯式模型解释了用2-甲基氧杂环丁烷获得的结果，阶梯式模型的最大可能步长为。9 kJ mol –1。使用206 nm辐射会产生具有过量能量的亚甲基，其中一些在反应时仍会存在，并导致生成2-甲基氧杂环丁烷，其平均寿命约为使用313 nm辐射时所激发分子的一半。

  The low-temperature oxidation of the five hexane isomers (n-hexane, 2-methyl-pentane, 3-methyl-pentane, 2,2-dimethylbutane, and 2,3-dimethylbutane) was studied in a jet-stirred reactor (JSR) at atmospheric pressure under stoichiometric conditions between 550 and 1000 K. The evolution of reactant and product mole fraction profiles were recorded as a function of the temperature using two analytical methods: gas chromatography and synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS). Experimental data obtained with both methods were in good agreement for the five fuels. These data were used to compare the reactivity and the nature of the reaction products and their distribution. At low temperature (below 800 K), n-hexane was the most reactive isomer. The two methyl-pentane isomers have about the same reactivity, which was lower than that of n-hexane. 2,2-Dimethylbutane was less reactive than the two methyl-pentane isomers, and 2,3-dimethylbutane was the least reactive isomer. These observations are in good agreement with research octane numbers given in the literature. Cyclic ethers with rings including 3, 4, 5, and 6 atoms have been identified and quantified for the five fuels. While the cyclic ether distribution was notably more detailed than in other literature of JSR studies of branched alkane oxidation, some oxiranes were missing among the cyclic ethers expected from methyl-pentanes. Using SVUV-PIMS, the formation of C-2-C-3 monocarboxylic acids, ketohydroperoxides, and species with two carbonyl groups have also been observed, supporting their possible formation from branched reactants. This is in line with what was previously experimentally demonstrated from linear fuels. Possible structures and ways of decomposition of the most probable ketohydroperoxides were discussed. Above 800 K, all five isomers have about the same reactivity, with a larger formation from branched alkanes of some unsaturated species, such as allene and propyne, which are known to be soot precursors.
