Halogenated hydrocarbons (HHCs) are commonly used as flame suppressants and refrigerant working fluids. The first generation of these compounds, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), depleted the ozone layer and were banned worldwide under the Montreal Protocol in the 1980s. The second generation, hydrofluorocarbons (HFCs), are ozone-friendly but are currently being phased out due to their high global warming potentials (GWPs). Despite these controls on high-GWP HFC production, a recent study discovered that emissions of HFC-23 (CHF 3 ), a potent greenhouse gas, reached an historic high in 2018. To address these environmental concerns, several low-GWP HHC refrigerants and suppressants have been proposed. However, the chemical properties that make these HFCs more environmentally friendly also increase their flammability. Therefore, the combustion properties of these proposed HHCs are of the utmost concern. Since experimental studies of these properties are complex and costly, predictive kinetic modeling of HHC combustion is crucial in screening proposed compounds in order to facilitate their innovation and implementation.
