Temperature dependence of the gas-phase reactions F+CHFO,CFO+F,and CFO+CFO

The rate coefficients for the reactions CHFO+F, CFO+F and the self-reaction of CFO were determined over the temperature range of 222–298 K. A computer controlled discharge-flow system with mass spectrometric detection was used. The results are expressed in the Arrhenius form (with energies in J): CHFO+F→CFO+HF: _k1(_T)=(9.7±0.7)·10⁻¹² exp[−(5940±150)/RT] cm³ molecule⁻¹ s⁻¹ CFO+F+M→CF₂O+M: FORMULA DISC=“MATH”>_k2(_T)=(2.60±1.17)·10⁻¹⁰ exp[−(10110±1250)/RT cm³ molecule⁻¹ s⁻¹FORMULA CFO+CFO→CF₂O+CO: _k3(_T)=(3.77±2.7)·10⁻¹⁰ exp[−(8350±2800)/RT] cm³ molecule⁻¹ s⁻¹ © 1998 John Wiley & Sons, Inc.
