Synopsis

Steady oscillations in the recorded gas temperature have been observed in a series of experiments in which the vapour-phase chlorination of methyl chloride was carried out. The instability was reproducible and persisted within a sharply defined range of reaction temperatures. A mathematical analysis of the dynamics of the reacting system is found to predict closely the nature and frequency of the oscillations and the range of experimental conditions within which they occur.
