✦ Synopsis

Abstract

The thermal decompositions of ethyl chloride, iso propyl chloride, and tertiary butyl chloride were studied in a static system in the pressure range of 0.1–300 torr. The following Arrhenius equations for the high‐pressure limit were obtained:

The pressure dependence of the first‐order rate constant (falloff) for these three unimolecular dehydrochlorination reactions, starting with approximately equal k~ω~ values, by proper choice of temperature, is shifted to lower pressures with increasing molecular size:
