英文摘要:
Smog chamber techniques were used to determine k(CH3OCF2CHCl2 + Cl)=(5.04 +/- 0.75) x10(-13), k(CH3OCF2CHCl2 + OH)=(2.18 +/- 0.38) x10(-13), and k (CH3OCF2CHCl2 + O-3) < 1.5x10(-22) cm(3) molecule(-1) s(-1) in 700 Torr of N-2/air diluent at 296-300 K. The IR spectrum for CH3OCF2CHCl2 is reported. CH3OCF2CHCl2 is a short-lived compound with an estimated atmospheric lifetime of similar to 54 days. The ozone depletion potential for CH3OCF2CHCl2 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.
