“…The SAR rate coefficient for ethylene oxide + OH using the literature value of 0.017 for the three-membered ring factor is 2.2 × 10 −13 cm 3 molecule −1 s −1 . However, when this value is changed to 0.0055, the predicted rate coefficient decreases to 7.3 × 10 −14 cm −3 molecule −1 s −1 , which is in better agreement with the experimental literature value for this rate coefficient [4,30,31]. Thus, the literature is consistent with the use of this lower threemembered ring strain factor for epoxides.…”

The kinetics and mechanism of gas-phase propylene oxide (PPO) reactions were studied in a 142-L reaction chamber by long-path Fourier transform infrared spectroscopy at atmospheric pressure and 298 K. Rate coefficients for the reaction of PPO with ozone (O 3 ), chlorine atoms (Cl), and hydroxyl radicals (OH) were measured using the relative rate technique. Product yields of acetic acid, acetic formic anhydride, formic acid, and carbon monoxide were determined for the following reactions: PPO with Cl both in the presence and absence of NO, PPO with OH and NO, methyl acetate with Cl both in the presence and absence of NO, and ethyl formate with Cl both in the presence and absence of NO. The measured rate coefficients for PPO with O 3 , Cl, and OH are <3.5 × 10 −21 cm 3 molecule −1 s −1 , (3.0 ± 0.7) × 10 −11 cm 3 molecule −1 s −1 , and (3.0 ± 1.0) × 10 −13 cm 3 molecule −1 s −1 , respectively. The carbon balance for the products measured ranged from 10% (for OH + PPO) to 100% (for Cl + methyl acetate in the absence of NO). The mechanistic and atmospheric implications of these measurements are discussed. C

“…At room temperature and low total pressure (,-~ 15 torr) the values of Reference 94 are about 80 times larger than those of Reference 92. Experiments in the range 298-850K, and at 10-40 torr, indicate a large increase in the activation energy above ~500K [94]. The pressure dependence of the rate constant in the region <500K has been attributed to formation of an OH-HCN adduct with unspecified final products [91,94].…”

“…The reaction was studied by Phillips [91,92] in the temperature range 298-563K and low pressure, and by Zelhaer and coworkers [93,94] over the ranges 298-500K and 15-375 torr. The rate constant was found to increase with the pressure.…”

“…This is an overlooked positive aspect of phosphine on plant growth. Phosphine is also a reactive atmospheric trace gas, which competes with methane and other greenhouse gases for hydroxyl radicals, because PH 3 reacts quickly with hydroxyl radicals in the atmosphere (Fritz et al, 1982), and thus enhances an indirect greenhouse effect, or the so-called coupling effect (Prinn, 1994). On the other hand, phosphine itself is a toxic substance, which inhibits the growth of soil microorganisms and damages crop roots.…”
