Abstract |
Relative rate constants for the reaction of OH radicals with a series of branched alkanes have been determined at 297 + or - 2 K, using methyl nitrite photolysis in air as a source of OH radicals. Rate constants for 2,2-dimethylbutane, 2,4-dimethylpentane and methylcyclohexane have been determined for the first time, while those for the other branched alkanes are in generally good agreement with the literature data. Primary, secondary, and tertiary group rate constants at room temperature have been derived from these and previous data for alkanes and unstrained cycloalkanes, with the secondary and tertiary group rate constants depending in a systematic manner of the identify of the neighboring groups. The use of these group rate constants, together with a previous determination of the effect of ring strain energy on the OH radical rate constants for a series of cycloalkanes, allows the a-priori estimation of OH radical rate constants for alkanes and cycloalkanes at room temperature. |
