Study on the NO{sub 3} radical reactivity: Reactions with cyclic alkenes
- Univ. de Castilla-La Mancha, Ciudad Real (Spain). Facultad de Quimicas
Much effort has been expended in studies of NO{sub 3} radical chemistry. The emphasis has been placed on investigating reaction rates and products of various organic and inorganic compounds to understand the behavior of this reactive radical in the atmosphere. The rate constants of the reactions of NO{sub 3} with cyclopentene, cyclohexene, cycloheptene, 1-methylcyclohexene, and methylenecyclohexane have been measured as a function of temperature at low pressure in a fast flow system with LiF detection of NO{sub 3}. The measured room temperature (298 K) rate constants for these reactions are given. The proposed Arrhenius expressions for the studied reactions are also given. The influence of substitution in the double bond and the ring size effect in unsubstituted cyclic monoalkenes has been investigated for the reactivity of the NO{sub 3} radical reactions. The rate coefficients and the activation energies for the reaction of the nitrate radical with methylenecyclohexane and 1-methylcyclohexene have also been compared with the corresponding values of some selected terpenes with similar structure to these compounds.
