• Tropospheric Degradation Products of Novel Hydrofluoropolyethers

  日期：1997.6.1

  The Cl atom-initiated photooxidations of the hydrofluoropolyethers (HFPEs) HCF2OCF2OCF2CF2OCF2H, HCF2OCF2CF2OCF2H, and HCF2OCF2OCF2H in air produced C(O)F-2 as the only carbon-containing product, with observed average C(O)F-2 molar formation yields of 4.73, 3.77, and 2.82, respectively. The C(O)F-2 molar formation yields during the early stages of the reactions were observed to be closer to the number of C atoms in each parent HFPE. On the basis of current knowledge concerning the degradation pathways of hydrofluorocarbons and hydrochlorofluorocarbons, it is expected that C(O)F-2 will also be produced with near unit yield per C atom from the above HFPEs in the troposphere, where loss processes would be initiated primarily by reaction with OH radicals. The rate constants for reaction with the Cl atom at 298 +/- 2 K were determined for the HFPEs by a relative rate method that employed CF3CF2H as the reference compound [k(Cl + CF2CF2H) = (2.4 +/- 0.5) x 10(-16) cm(3) molecule(-1) s(-1)], with measured values of (in units of 10(-17) cm(3) molecule(-1) s(-1)) HCF2OCF2OCF2CF2OCF2H, 3.6 +/- 0.8; HCF2OCF2CF2OCF2H, 4.5 +/- 1.0; and HCF2OCF2OCF2H, 5.0 +/- 1.1.

The Cl-initiated atmospheric oxidation of HCF2OCF2OCF2CF2OCF2H and the sample of HCF2O(CF2O)n(CF2CF2O)mCF2H used in this work gave COF2 in molar yields of (476 ± 36)% and (859 ± 63)%, respectively, with no other observable carbon containing products (i.e., essentially complete
