摘要：

A fast-flow apparatus with mass spectrometric detection was used to study the system F + CHFO between 2 and 3.5 mbar total pressure. The rate constant of the primary reaction was evaluated directly to yield at 298 K k(1) = (8.8 +/- 1.4) * 10(-13) cM3 * molecule-1 * s-1. Numerical modelling was used to determine the rate constant at 298 K of the subsequent reaction CFO + CFO --> CF2O + CO: k(2) = (4.9 +/- 2.0) * 10(-11) CM3 * molecule-1 * s-1. The possible occurrences of secondary reactions, CFO + F + M --> CF2O + M, and CFO + F2 --> CF2O + F, can be excluded under the present conditions. (C) 1993 John Wiley & Sons, Inc.
