The oxidation of acetaldehyde was studied with a shock tube connected with a mass spectrometer over the temperature range 1400-1700 K and the total pressure range 200-400 Torr. The induction period τ was measured by monitoring the oxygen concentration, and the following equation was found, τ=1.24×10-12 [CH3CHO] 0.4 [O2] -0.8 exp (41000/RT) s, where the concentration is expressed in mol/cc. Data analysis using 48-reaction mechanism was carried out, and the mechanism was discussed.
