A shock tube and laser absorption study of ignition delay times and OH reaction rates of ketones: 2-Butanone and 3-buten-2-one

Site-Specific Rate Constant Measurements for Primary and Secondary H- and D-Abstraction by OH Radicals: Propane and n-Butane

“…The method and setup were described previously [18][19][20] and only a brief description is given here. The shock tube is made of a 9 m driver section and a 9 m driven section, with an inner diameter of 14.2 cm.…”

“…These branching ratios are kept unchanged when fitting the experimental profiles. In fact, the determination of overall rate constant (k 1 = k 1a + k 1b ) is insensitive to the branching ratios because of the pseudo-first-order conditions 18 . Figure 2 shows a representative measured OH profile at 1051 K and 2 atm.…”

“…Propane + OH is the dominant reaction under all conditions of the current study. However, minor interferences from secondary reactions occur and the rates of the important secondary reactions are updated based on the suggestions given in 18 . Propane + OH has two different pathways:…”

An experimental and theoretical study on the kinetic isotope effect of C2H6 and C2D6 reaction with OH

“…As the details of our experimental facility could be found elsewhere [25], only a brief description is provided here. The LPST has 9 m long driver and driven sections with an inner diameter of 14.2 cm.…”

“…Hydroxyl radicals were produced by rapid thermal decomposition of tert-butyl hydroperoxide (TBHP), which is known to be a clean thermolytic source of OH radicals and had been validated in many earlier studies [25,29,30]. Hydroxyl radicals were measured by using the well-characterized R1 (5) Several reflected-shock experiments were conducted for each fuel (C 2 H 6 and C 2 D 6 ) and the concentrations of reactants (fuel, TBHP) were chosen based on sensitivity analyses to achieve pseudo-first-order kinetics.…”
