constants for the reactions of hydroxyl radicals (OH) with
1,1,1,3,3,3-hexafluoroisopropyl methyl ether (CH3-O-CH(CF3)2) and 4-bromo-3-chloro-3,4,4-trifluoro-1-butene
(CH2CH-CFCl-CF2Br) have been measured
over the temperature range 230–370 K to give the following
Arrhenius expressions: kCH3OCH(CF3)2(T) = 7.69 × 10–14 × (T/298)2.99 × exp(+342/T), cm3 molecule–1 s–1, and kCH2CHCFClCF2Br(T) = (6.45 ± 0.72) × 10–13 × exp{+(424
± 32)/T}, cm3 molecule–1 s–1. Atmospheric lifetimes of compounds were estimated
to be 67 days and 4.5 days, respectively. UV absorption spectrum of
CH2CH-CFCl-CF2Br between 164 and 260
nm and IR absorption spectra of both compounds between 450 and 1600
cm–1 were measured at room temperature.
