✦ Synopsis

The thermal decomposition of pyruvic acid into carbon dioxide and acetaldehyde is a unimolecular first-order reaction and takes place according to the rate equation. loyk 13.53--41.250,'4.575 K. These parameters contrast markedly with those recently reported. viz. logk = 7.19-27.700/4.575 K and confirm that the latter, which gave an unacceptably low value for the frequency factor. are anomalous. The lower reactivity of p? rt1v:c acid compared to oxalic acid is interpreted in terms of normal electronic effects.

## Abstract The kinetics of gas‐phase decomposition of methyl isocyanate have been investigated in the range of 427–548°C. Two decomposition routes are followed; the predominant one is a radical‐chain process giving CO, H~2~, and HCN as major products, which has an order of 1.5 and an Arrhenius equ
