  Tropospheric Degradation Products of Novel Hydrofluoropolyethers

  摘要：

  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.

  三种全氟聚醚盐的热脱羧研究

  摘要：

  研究了三种链长较短的二羧酸全氟聚醚钾盐的热脱羧反应，并确定了主要反应的产物和动力学。从速率常数和Arrhenius参数数据来看，第二次脱羧在数量上似乎与第一次接近。
