摘要:
基于GC、GC-MS和KM900手持式烟气分析仪测试手段,研究了全氟己酮在管式反应器中滞留时间为2 s和5 s、裂解温度为500~750 ℃时的热裂解规律。结果表明:全氟己酮在550 ℃时开始分解,超过650 ℃裂解剧烈;主要裂解气体产物为十氟丁烷、六氟丙烯和全氟异戊烷;随着裂解温度和滞留时间的增加,全氟己酮裂解程度加剧,十氟丁烷和六氟丙烯生成量增加,全氟异戊烷的生成量先增加后减少;值得重视的是全氟己酮高温热裂解时有剧毒气体全氟异丁烯和毒性气体一氧化碳产生。
Abstract:
The thermal pyrolysis of C6F-ketone was studied in a stainless tubular reactor under atmospheric pressure and attemperatures between 500 ℃ and 750 ℃ with residence times of 2 s and 5 s. The pyrolysis gaseous products were analyzedby on-line gas chromatography (GC), gas chromatographymass spectrometry (GC-MS) and KM900 handheld combustion analyzer. The results indicate that the thermal pyrolysis of C6F-ketone initiates at about 550 ℃ and becomes intense at 650 ℃. As both pyrolysis temperature and residence time increase, the thermal pyrolysis of C6F-ketone is triggered, which makes the concentration of C6F-ketone plummet, the yields of main gaseous products perflubutane, hexafluoropropylene increase and 1,1,1,2,2,3,4,4,4-nonafluoro-3-(trifluoromethyl) butane decrease after its peak. Besides, highly toxic gaseous products,perfluoroisobutene and carbon monoxide, were detected in the thermal pyrolysis process.
