Abstract

The rate coefficients for the chemical reactions (species loss rates, quenching excluded) of the refrigerants CH2F2 (HFC-32), CHClF2 (HFC-22) and CH2FCF3 (HFC-134a), and the solvent CH3CCl3 with O(1D) are determined relative to CH4 + O(1D) at 298 K. The resulting rates k(CH2F2 + O(1D)) = (4.78 ± 1.03) × 10−11 cm3 molecule−1 s−1, k(CHClF2 + O(1D)) = (8.69 ± 1.72) × 10−11 cm3 molecule−1 s−1, k(CH2FCF3 + O(1D)) = (6.10 ± 1.43) × 10−11 cm3 molecule−1 s−1 are compared to available literature data. The reaction rate of 1,1,1-trichloroethane with O(1D) is determined for the first time, k(CH3CCl3 + O(1D)) = (2.93 ± 1.20) × 10−10 cm3 molecule−1 s−1.
