Notes:
Absolute rate coefficients for the reactions of the hydroxyl radical with dimethyl ether (k1) and diethyl ether (k2) were measured over the temperature range 295-442 K. The rate coefficient data, in the units cm3 molecule-1 s-1, were fitted to the Arrhenius equations k1 (T) = (1.04 ± 0.10) × 10-11 exp[-(739 ± 67 cal mol-1)/RT] and k2(T) = (9.13 ± 0.35) × 10-12 exp[+(228 ± 27 kcal mol-1)/RT], respectively, in which the stated error limits are 2σ values. Our results are compared with those of previous studies of hydrogen-atom abstraction from saturated hydrocarbons by OH. Correlations between measured reaction-rate coefficients and C—H bond-dissociation energies are discussed.
