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(D-1) are determined relative to CH4 + O(D-1) at 298 K. The resulting rates k(CH2F2 + O(D-1)) = (4.78 +/- 1.03) x 10 (11) cm(3) molecule (1) s (1), k(CHClF2 + O(D-1)) = (8.69 +/- 1.72) x 10 (11) cm(3) molecule (1) s (1), k(CH2FCF3 + O(D-1)) = (6.10 +/- 1.43) x 10 (11) cm(3) molecule (1) s (1) are compared to available literature data. The reaction rate of 1,1,1-trichloroethane with O(D-1) is determined for the first time, k(CH3CCl3 + O(D-1)) = (2.93 +/- 1.20) x 10 (10) cm(3) molecule (1) s (1).
