Atmospheric chemistry of methoxyflurane (CH3OCF2CHCl2): Products and mechanisms

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

Long pathlength/FTIR smog chamber techniques were used to determine the Cl atom initiated atmospheric oxidation mechanisms for methoxyflurane (CH3OCF2CHCl2) in 700 Torr of air or O2 diluent at 296 K. The oxidation of CH3OCF2CHCl2 in both air and O2 diluent gave one primary carbonyl-containing product in approximately 100% yield and one secondary bi-carbonyl product in addition to COF2 and COCl2, the latter two both with initial molar yields of 2 ± 1%. A mechanism is proposed for the oxidation of methoxyflurane which explains the observed product distribution. IR spectra for HC(O)OCF2CHCl2 and HC(O)OCF2C(O)Cl are calculated and reported.
