High-Temperature Unimolecular Decomposition of Ethyl Chloroformate: Comparison of the Secondary Competing Steps with Ethyl Formate

  • Conference paper
Shock Waves @ Marseille II

Abstract

The thermal decomposition of ethyl chloroformate has been investigated behind reflected shock waves. It is shown that the initiation step proceeds through a molecular elimination to produce ethylene and chloroformic acid likely as in the case of ethyl formate. It is found that in the consecutive reaction of the produced acid, decarboxylation occurs dominantly contrary to the case of formic acid in which the dehydration is more important. The decomposition mechanism is discussed on the basis of a theoretical calculation.
