Kinetics Study of the Reactions of 4-Methyl-2-Pentanone and m-Ethyl Toluene with Hydroxyl Radicals between 240 and 340 K and 1–8 Torr Using the Relative Rate/Discharge Flow/Mass Spectrometry Technique
Abstract:The kinetics of reactions of 4-methyl-2-pentanone (MIBK) and m-ethyl toluene (MET) with hydroxyl radicals has been studied at a total pressure of 1−8 Torr and 240−340 K using the RR/DF/MS technique. The rate constant for the reaction of MIBK with the hydroxyl radical was found to be essentially pressure-independent in the range of 1−3 Torr. The rate constant for MET reaction with the hydroxyl radical increased with pressure at 1−5 Torr, and a high pressure limit was reached at 5 Torr. At 298 K, rate constants … Show more
