Suppression of hydrocarbon flames by organophosphorus compounds and their based mixtures

Abstract

The minimum extinguishing concentrations of mixtures consisting of organophosphorus and iodine-containing compounds and inert diluents were measured with the cupburner and cylinder techniques. The results obtained were used to develop and test new effective fire-suppressing compositions whose components exhibit a synergetic effect. For these mixtures, the lower temperature limit of application was estimated.

“…3,4 Our interest in phosphorus-containing species stems from the (experimental) observation that these molecules can be used as efficient coke-reducing additives within thermal cracking processes. 5,6 Unfortunately, the development of kinetic models for this industrially important process has been hampered by a lack of accurate thermochemical and kinetic data as experimental enthalpies of formation are often unknown or known with relatively large uncertainties.…”

“…Phosphorus-containing molecules are important in a broad variety of chemical processes, such as biological systems, the synthesis of industrial chemicals, decomposition of pesticides and insecticides, catalytic applications (ligands for transition metals), and flame retardation. , Our interest in phosphorus-containing species stems from the (experimental) observation that these molecules can be used as efficient coke-reducing additives within thermal cracking processes. , Unfortunately, the development of kinetic models for this industrially important process has been hampered by a lack of accurate thermochemical and kinetic data as experimental enthalpies of formation are often unknown or known with relatively large uncertainties. Computational results can hence offer a viable alternative. , …”
