✦ Synopsis

Rate constant ratios of the reactions of CFsO radicals with a number of hydrocarbons have been determiued at 298 + 2 K and atmospheric pressure using a relative rate method. Using a previously determined value k(CF,O+ CsHs) = I .2 x lo-i2 cm3 molecule-' s-i these rate constant mtios,provide estimates of tbe rate constants: k(CFsO+CH,)= ( .2kO.l) x 10-14, k(CF,O+ c-C,He,)=(3.6~0.2)x10-13, k(CF,O+C,Hs)=(4.7+0.7)~10-'*, k(CF~O+(CHS),CH)=(7.2-f0.5)x10-I*, k(CF,O+ C~H4)=(3.0~0.1)~10-1'andk(CF,O+C~)=(3,6~0.1)~lO-L'cm3mol~ule~'~~'.Theimportanceofthereactionsof CFsO radicals with hydrocarbons under atmospheric conditions is discussed.
