A mathematical model is devised to consider the thermokinetic coupling
of an active intermediate and temperature in the slow oxidation of
hydrocarbon. With a single set of assumed rate constants it is shown
that explosion limits, cool flame oscillation limits, oscillation
period and amplitude, explosion peninsula (lobe), and negative temperature
coefficient effect can all be calculated in agreement with experimental
observations. Detail kinetics are discussed. The RCO radical is tentatively
identified as the autocatalytic carrier. The proposed branching scheme
conforms with a previous proposal made by Knox and Norrish in their
work on the oxidation of propane.
