Effect of Oxidation of Fluorohydrocarbons and Fluorocarbons on Their Characteristics as Gas Combustion Suppressing Agents
The combustion of some fluorohydrocarbons (FHCs) and fluorocarbons (FCs) in oxygen was studied in a closed vessel at initially room temperature and atmospheric pressure. The chemical mechanism of oxidation of these compounds was discussed. To improve the characteristics of fluorinated compounds as gas combustion suppressing agents, an oxidation inhibitor should be introduced in them. After the addition of C3H8, C4H10, and C3H6 to the fluorinated compound, its minimum phlegmatizing concentration (MPC) for methane-air mixtures significantly decreased.
