The rate of decomposition of allyl iodide has been measured from 742plusmn;K to 1068±K and from 169 to 1429 torr using a shock tube method in which the disappearance of allyl iodide and the appearance of iodine are followed simultaneously. The kinetics are first order in allyl iodide and probably are slightly dependent upon total pressure. Mathematical modeling shows that they are compatible with a mechanism consisting of three reactions:The experiments yield the rate constant k 1 , the high‐pressure limiting value of which is found to be\documentclass{article}\pagestyle{empty}\begin{document}$$\log _{10} k_\infty (\sec ^{ - 1}) = (14.45 \pm 0.4) - (42.8 \pm 2.4{\rm kcal})/2.3RT$$\end{document} in reasonable agreement with that predicted using the methods of Benson and O'Neal [1].
