Web坊間常見海龍，有 海龍1301 （Halon 1301， CF 3 Br ）、 海龍1211 （Halon 1211， CF 2 ClBr ）等。 以前者為例，海龍是一種非常乾淨的滅火劑，不會留下粉末、泡末，也不會有水份。 因此常被配置於高精密儀器、儀表附近，如飛機、船艙、 機房 、 捷運系統 等。 但是隨著 地球大氣層 的 臭氧層 空洞越來越大，海龍因為有破壞臭氧層的高度疑慮，也和其他 … Webscope. For the CF3Br experiments, the laser is tuned to the Ql(5) line in the (1.0) vibra- tional band of the A%+ tX2n transition in OH. However, 285 nm light strongly pho- todissociates CF3I to produce CF3 + I. For the CF3I experiments, the laser is instead tuned to the Pl(5) line in the (0,O) vibrational banh of the A2X+ t-sn transition in OH.

WebThe chemical compound CF3I is a replacement candidate for the in-flight fire extinguishing Halon 1301 CF3Br. One concern in choosing a suitable replacement for CF3Br is the toxicity of the replacement candidate. Since toxicological data comparing CF3Br and CF3I are not available, this comparison was done using a computer model for toxic endpoints. …
