A new mechanism for the low temperature oxidation of hydrocarbons in the gas phase

摘要: Abstract An important requirement of any mechanism for the low temperature oxidation alkanes at 300° to 400°C is shown be inclusion processes conversion HO2 OH radicals. This must involve co-oxidation olefin, AB, which primary product most alkanes. The key sequenceAB→ABOOH→OOABOOH complete explains major features alkane and olefin in regime. It existence negative coefficient terms instability ABOOH radical effect structure on ease oxidation. paper includes (a) thermochemical data peroxides, peroxy radicals hydroperoxide radicals, (b) estimates equilibrium constants lifetimes
