Abstract:
Smog chamber/FTIR techniques were used to measure k(Cl+HCF2O(CF2CF2O)xCF2H) = (5.3 Æ 1.5) 10-17 cm3 molecule-1 s-1 in 700 Torr of N2/O2 diluent at 296 Æ 1 K. The Cl-initiated atmospheric oxidation of HCF2O(CF2CF2O)xCF2H, x = 2,3 and 4, gave COF2 in molar yields of (593 Æ 41) %, (758 Æ 71) % and (939 Æ 73) %, respectively, with no other observable carbon-containing products (i.e., essentially complete conversion of the hydrofluoropolyethers into COF2). Quantitative infrared spectra for
