Abstract
Oscillations of the OH radical concentration in the gas‐phase oxidation of acetaldehyde in a CSTR are monitored by means of laser‐induced fluorescence. The oscillations of acetaldehyde in this reaction are measured with UV absorption. Light emission, pressure, and temperature oscillations are recorded, and phase relations between these oscillations are presented. In an Appendix, we present a 12‐step, five‐variable, thermokinetic scheme which uses peracetic acid as the branching agent in the chain‐branching mechanism. This model qualitatively reproduces the oscillatory behavior found in this combustion system.Keywords
