Abstract

Rate constants for the reactions of cyc-CF2CF2CF2CHFCH2- (k1) and trans-cyc-CF2CF2CF2CHFCHF- (k2) with OH radicals were assessed by a relative rate method. The values were determined as (9.35 ± 5.83) × 10-13 exp[-(1197 ± 180)/T] and (8.02 ± 2.17) × 10-13 exp[-(1198 ± 80)/T] between 253 and 328 K; and (1.72 ± 0.05) × 10-14 and (1.43 ± 0.03) × 10-14 cm3 molecule-1 s-1 at 298 K, respectively. The atmospheric lifetimes were 2.8 and 3.2 years; the 100-year time horizon global warming potentials were estimated to be 211 and 241, respectively.
