摘要
Abstract
The thermal pyrolysis of C6 F-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 C6 F-ketone initiates at about 550 ℃ and becomes intense at 650 ℃. As both pyrolysis temperature and residence time increase, the thermal pyrolysis of C6 F-ketone is trig-gered, which makes the concentration of C6 F-ketone plummet, the yields of main gaseous products perflubutane, hexaflu-oropropylene 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.关键词
