✦ Synopsis


Vinyl and isopropyl radicals were generated by the pyrolysis of azoisopropane in the presence of acrolein at 473-563 K. Reaction products were analyzed by gas chromatography. Rate constant ratios k , / k , = 0.02 lr 0.01 and k 4 / k 3 : 0.01 f 0.005 are suggested for the following reactions:

(1)

The rate constant ratio of reactions ( 7) and (c) obeys the Arrhenius equation k 7 / k f " = (1.02 5 0.7)107exp[ -(28.42 f 2.97)kJ/RT] dm ,'* mol-"* s-"' (CH,),CHN=NCH(CH,), + C,H,. .--f CzH4 + (CH,),C-N=NCH(CH,), (8) (9) CzH3CH0 + C,H,. + C,H4 + C,H,CO. The Arrhenius equation was derived for (k, + k , )
