摘要：

The photochemical reaction between CF3OCl and CF2CCl2 has been investigated with light of wavelength 253.7 nm between 15 and 30 °C. The main product is CF3OCF2CCl3. Very small amounts of CF2ClCCl3 and (CF3OCF2CCl2)2 are also formed. The reaction is a chain reaction. Its rate is proportional to the square root of the absorbed light and proportional to the CF3OCl pressure. Above a limiting pressure CF2CCl2 and the total pressure have no influence. The experimental results can be explained using the following mechanism: {A figure is presented}. The temperature coefficient of the rate constant k = k5(2/k6) 1 2 is 1.32 ± 0.10 for each 10 °C. E = E5 - 1 2E6, where E6 ≈ 0 and E5 = 5.0 ± 1.5 kcal. {A figure is presented} At 30 °C with 100 Torr CF3OCl and Iabs = 0.040 Torr min-1 {A figure is presented}. © 1979.
