Abstract

Smog chamber techniques were used to determine k(CH ₃ OCF ₂ CHCl ₂ + Cl) = (5.04 ± 0.75) × 10 ⁻¹³ , k(CH ₃ OCF ₂ CHCl ₂ + OH) = (2.18 ± 0.38) × 10 ⁻¹³ , and k(CH ₃ OCF ₂ CHCl ₂ + O ₃ ) < 1.5 × 10 ⁻²² cm ³ molecule ⁻¹ s ⁻¹ in 700 Torr of N ₂ /air diluent at 296–300 K. The IR spectrum for CH ₃ OCF ₂ CHCl ₂ is reported. CH ₃ OCF ₂ CHCl ₂ is a short-lived compound with an estimated atmospheric lifetime of ∼54 days. The ozone depletion potential for CH ₃ OCF ₂ CHCl ₂ was estimated to be on the order of 0.001 and a 100-year global warming potential of 4 was determined using a lifetime-corrected radiative efficiency estimation. Results are discussed with respect to the atmospheric chemistry of halogenated anesthetic gases.
