由于机载哈龙等灭火剂被联合国限制和淘汰以及全氟和多氟烷基物质(PFAS,per-and polyfluoroalkyl sub-stances)的即将禁用,开发出能够完全满足机载需求的哈龙替代灭火剂成为热点研究话题.三氟碘甲烷(CF3I,trifluoroiodomethane)是一种不属于PFAS的高效灭火剂,灭火效率接近哈龙-1301 并具有优异的环保性能,被视为最有潜力替代哈龙灭火剂的物质之一.目前,CF3I在民用航空领域应用面临的主要问题是合成成本较高.因此,本文总结了现有的CF3I合成工艺并选择出最优技术路线,为推进CF3I在民航领域的应用以增强未来民航热灾害防控能力提供指导.
Due to the restriction and elimination of airborne halons and other fire extinguishing agents by the United Nations and the imminent banning of per-and polyfluoroalkyl substances(PFAS),the development of halon alternative fire extinguishing agents that can fully satisfy airborne needs has become a hot research topic.Trifluoroiodomethane(CF3I)is a kind of high efficient fire extinguishing agent that does not belong to PFAS,whose fire extinguishing ef-ficiency is close to that of Halon-1301 and has excellent environmental performance,being considered as one of the substances with the greatest potential to replace halon fire extinguishing agents.At present,the main problem faced by the application of CF3I in civil aviation field is the high synthesis cost.Therefore,this paper summarizes the existing synthesis processes of CF3I and selects the optimal technological route,which can provide guidance for promoting the application of CF3I in civil aviation field to enhance future civil aviation thermal disaster prevention and control capability.
