The absolute rate constants determined for the additions of FCPh, ClCPh, and BrCPh to Me2C=CMez, MepC=CHMe, trans-MeCH=CHEt, and n-BuCH=CH2 appear to follow a reactivity/selectivity pattern of the "normal" (inverse) type.
Using a relative rate method, rate constants have been determined at 296 5 2 K for the gas-phase reactions of the OH radical with toluene, the xylenes, and the trimethylbenzenes. Using the recommended literature rate constant for the reaction of OH radicals with propene of (2.66 2 0.40) x lo-" cm3 m
The relative rates of consumption of neopentane and of H 2 have been determined for small additions of neopentane to slowly reacting mixtures of H 2 + 02 in aged boric-acid-coated ves-O sels at 480 C. Interpretahon of the results gives rate constants for the attack of H and OH on O , . neopentane a
Recently, Atkinson et al. [l] reported measurements on the reaction of ozone with a series of carbonyls. In that study a correlation between ozone addition and hydroxyl-radical addition reactions was employed to predict OH addition coefficients for acrolein and crotonaldehyde of approximately 2 X an
