- 摘要：
- Hydrofluoroolefins (HFOs, CxF2x+1CH=CH2) have great potential to replace hydrofluorocarbons (HFCs) as refrigerants. Here the kinetics for the reaction of syn-CH3CHOO with CF3CH=CH2 (HFO-1243zf), the simplest of HFOs, have been studied in a flash photolysis flow reactor at a total pressure of 50 Torr, by using the OH laser-induced fluorescence (LIF) method. The bimolecular reaction rate coefficients were measured at temperatures ranging from 283 to 318 K. A weak positive temperature dependence was observed, with an activation energy of 1.41 +/- 0.12 kcal mol(-1). At 298 K, the measured rate coefficient was (2.42 +/- 0.51) x 10(-14) cm(3) s(-1), in the vicinity of the previously reported upper limit value for the reaction of CH2OO with CF3CH=CH2.
