Notes:
The kinetics of the reaction of O(3P) atoms with acetone were investigated using fast flow methods. The reaction was studied over a temperature range of 298 to 478°K. The specific rate constant obtained was (1.9 ± 0.4) × 1012 exp( - 5040 ± 180/1.987 T) cm3/mol·sec. The observation of a sizable primary H/D kinetic isotope effect in comparing rates of CH3COCH3 and CD3COCD3 led to the conclusion that the major reaction channel involves H atom abstraction, namely, \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm O}(^3 P) + {\rm CH}_3 {\rm COCH}_3 \to {\rm OH} + {\rm CH}_3 {\rm COCH}_3 $$\end{document}The rather low Arrhenius preexponential factor obtained in this reaction is compared and contrasted with those reported for other reactions of O(3P) with low molecular weight compounds.
