摘要

Cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(Z)) conforms the most of necessary requirements as an environment-friendly extinguishant. However, its fire suppression performance has not been investigated. In this study, the fire suppression effectiveness of HFO-1336 was evaluated by a cup burner apparatus. The extinguishing concentration indicates nonpositive correlation with the fuel flow. On the other hand, to characterize the heat release of the reaction kernel, the temperature of the flame base was measured. The results showed that the temperature increased with HFO-1336 loading in the range of 2-5%, while decreased as the concentration exceeded 5 %. In addition, the thermal decomposition properties of HFO-1336 were investigated over a temperature range of 100-800 degrees C and the products were analyzed by GC-MS. According to the detected products, the possible decomposition pathways were proposed and the extinguishing mechanism were discussed.
