Abstract

The thermal and methyl radical initiated decomposition of biacetylโ€d~6~ were investigated at conversions 5% over the temperature range of 387โ€412ยฐC and 251โ€“292ยฐC, respectively. The deuterated sample contained 10.5% biacetylโ€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/Dโ€abstraction reactions.

## Abstract The thermal decomposition of biacetyl has been studied at small percentage conversion over the temperature range 375โ€417ยฐC. For these conditions, an almost quantitative mass balance was obtained by gasโ€chromatographic analysis. The following equation was obtained for the overall reactio

Ihe thermal decomposition of azomethane-d6 has been studied. There is a short chain reaction, and measurements have been made of the rate of production of N, , CD, , and C,D, . .\ mechanism is suggested which accounts for these results fairly well. A com- parison is made with some similar results of

Multiphoton decomposition studies of 1 ,l,l-trichloroethane (TCE) with a pulsed CO1 laser arc reported. Pressure-independent decomposition, suggesting a collisionless process, was found for fluences of I I J/cm2 with 60 ns pulses, focused to a waist of 1.2 mm, for pressures up to 8 kPa. After 1300 p
