چکیده انگلیسی
The estimated atmospheric lifetimes (ÏOH) assuming kOH at 288 K were 3, 2, and 4 h for 2ClEVE, AE and AEE, respectively. The kinetic results are discussed in terms of the chemical structure of the unsaturated ethers by comparison with similar compounds. We also report ultraviolet (UV) and infrared (IR) absorption cross sections (Ïλ and Ï(νË), respectively). We estimate the photolysis rate coefficients in the solar UV actinic region to be less than 10â7 sâ1, implying that these compounds are not removed from the atmosphere by this process. In addition, from Ï(νË) and ÏOH, the global warming potential of each unsaturated ether was calculated to be almost zero. A discussion on the atmospheric implications of the titled compounds is presented.
