摘要

trans-1-Chloro-3,3,3-trifluoropropene (trans-CF3CH & xe001;CHCl) and 2-chloro-3,3,3-trifluoropropene (CF3CCl & xe001;CH2) have the potential to act as fire extinguishing agents, but their thermal decomposition mechanism and fire extinguishing performance have not been investigated. In this paper, thermal decomposition experiments and theoretical calculations were carried out to verify the possible thermal decomposition process and fire extinguishing performance of these potential fire extinguishing agents.trans-CF3CH & xe001;CHCl and CF3CCl & xe001;CH(2)can be decomposed into radicals, such as HCl, & x2d9;CF3, and & x2d9;CF2, which can consume & x2d9;OH and & x2d9;H radicals for fire suppression. Furthermore, the experimental and calculation results demonstrated that CF3CCl & xe001;CH(2)shows better thermal stability. To characterize the inhibitory efficiency oftrans-CF3CH & xe001;CHCl and CF3CCl & xe001;CH2, the minimum extinguishing concentrations were measured to be 6.8% and 6.9%, respectively. As a result,trans-CF3CH & xe001;CHCl and CF3CCl & xe001;CH(2)performed well, and their application as Halon substitutes is worth exploring.
