Abstract

The reaction rate coefficients for the E-CF₃CH[dbnd]CHCF₃ with OH were measured using the relative rate method: k (298 K) = (1.10 ± 0.02) × 10⁻¹³ and k (253–328 K) = (4.80 ± 0.92) × 10⁻¹³ exp [−(445 ± 28)/T] cm³ molecule⁻¹ s⁻¹. The atmospheric lifetime was 105 d, and the radiative efficiency (RE) was 0.171 W m⁻² ppb⁻¹. The estimated POCPs were evaluated as 0.8 and 0.3 under North-west European and USA urban conditions, respectively. The global warming potential was estimated as 7 for the global 100-year time horizon. CF₃OOOCF₃, CF₃C(O)H, COF₂, CO, and CO₂ were observed as carbon-containing products.
