The thermal and methyl radical initiated decomposition of biacetyl‐ d 6 were investigated at conversions 5% over the temperature range of 387‐412°C and 251–292°C, respectively. The deuterated sample contained 10.5% biacetyl‐ d 5 . The reaction products were analyzed by mass spectrometry. The following data could be determined from product ratios:where E is in kcal/mol With reasonable assumptions and literature data Arrhenius parameters for elementary steps were derived and discussed in particular with respect to isotopic effects in H/D‐abstraction reactions.
