Purpose. To analyze the theoretical aspects of the mechanisms of action of inhibitory and phlegmatizing fire extinguishing compositions.
Methods. Analytical, comparative evaluation of the mechanisms of action of inhibitory and phlegmatizing compounds.
Findings. Comparative analysis of theoretical aspects of the mechanisms of action of inhibitory and phlegmatizing compounds. The energy relationship between the chemical reaction of combustion and the thermal theory of extinction is shown. The values of bond breaking energies for some combustible molecules and their radicals are generalized. The standard breaking energies of chemical bonds of halogen derivatives of saturated hydrocarbons and their fire-extinguishing efficiency are compared, which indicates the relationship of their nature with the fire-extinguishing effect.
Application field of research. Modern approaches to the development of fire-extinguishing compositions for the intended purpose. Development of innovative materials and technologies.
