  Atmospheric Chemistry of Dimethoxymethane (CH₃OCH₂OCH₃):  Kinetics and Mechanism of Its Reaction with OH Radicals and Fate of the Alkoxy Radicals CH₃OCHO(•)OCH₃ and CH₃OCH₂OCH₂O(•)

  摘要：

  The rate constant for the reaction of dimethoxymethane (DMM) with OH radicals was determined to be (4.6 +/- 1.6) x 10(-12) at 346 +/- 3 K using a pulse radiolysis/transient UV absorption absolute rate technique and (5.3 +/- 1.0) x 10(-12) cm(3) molecule(-1) s(-1) at 295 +/- 2 K using an FTIR-smog chamber relative rate technique. The reaction of OH radicals with DMM occurs via an H-atom abstraction mechanism with 76% of the attack occurring on the -CH3 end groups and 24% on the central -CH2- unit. The atmospheric fate of the alkoxy radicals CH3OCH2OCH2O(.) and CH3OCHO(.)OCH3 at 296 K in 700 Torr of air was investigated using an FTIR-smog chamber technique. The sole atmospheric fate of CH3OCHO(.)OCH3 radicals is reaction with O-2 to give dimethyl carbonate (CH3OC(O)OCH3) and HO2 radicals. At least three loss processes were identified for CH3OCH2OCH2O(.) radicals. In 1 atm of air at 295 K, 84 +/- 4% of the CH3OCH2OCH2O(.) radicals react with O-2 while 7 +/- 3% undergo H-atom elimination; the fate of the remaining 9% is unclear. OH radical-initiated oxidation of DMM in 1 atm of air at 296 K results in a yield of 24% dimethyl carbonate and 69% methoxymethyl formate; the oxidation mechanism of the remaining 7% of DMM is unclear. Relative rate techniques were used to measure rate constants for the reaction of Cl atoms with CH3OCH2OCH3 and CH3OCH2OCHO of (1.4 +/- 0.2) x 10(-10) and (3.6 +/- 0.6) x 10(-11) cm(3) molecule(-1) s(-1), respectively. Results are discussed in the context of the atmospheric chemistry of DMM.
