chamber/FTIR techniques were used to measure k(Cl+HCF2O(CF2CF2O)xCF2H)=(5.3±1.5)×10−17 cm3 molecule−1 s−1 in 700 Torr of N2/O2 diluent at 296±1 K. The Cl‐initiated atmospheric oxidation of HCF2O(CF2CF2O)xCF2H, x=2,3 and 4, gave COF2 in molar yields of (593±41) %, (758±71) % and (939±73) %, respectively, with no other observable carbon‐containing products (i.e., essentially complete conversion of the
烟雾室/ FTIR技术用于在700 Torr的溶液中测量k(Cl + HCF 2 O(CF 2 CF 2 O)x CF 2 H)=(5.3±1.5)×10 -17 cm 3 分子-1 s -1 N 2 / O 2稀释剂的温度为296±1K。Cl引发HCF 2 O(CF 2 CF 2 O)x CF 2 H,x = 2,3和4的大气氧化,得到COF 2在(593±41)%,(758±71)%和(939±73)%,分别摩尔产率,没有其他可观察的含碳副产物(即氢氟聚醚的基本上完全转化成COF 2)。定量红外光谱为HCF 2 O(CF 2 CF 2 O)X CF 2 H(X = 2-4)记录并用于估计标题化合物(1.07,1.33的辐射效率,和1.36女男-2 ppb的-1)。全球变暖潜能值的3870,4730和5060(100年时间范围)进行了估计HCF 2 O(CF 2 CF 2 O)X CF
