Thermal Decomposition of Phosgene and Diphosgene [PDF]

The Journal of Physical Chemistry A, 2017
Phosgene (COCl2) is a toxic compound used or formed in a wide range of applications. The understanding of its thermal decomposition for destruction processes or in the event of accidental fire of stored reserves is a major safety issue. In this study, a detailed chemical kinetic model for the thermal decomposition and combustion of phosgene and ...
