Reactivity of 3-hydroxy-3-methyl-2-butanone: Photolysis and reaction kinetics
25 26 Hydroxycarbonyl compounds are important secondary reaction products in the 27 oxidation of Volatile Organic Compounds (VOCs) in the atmosphere. The 28 atmospheric fate of these oxygenated VOCs is however poorly understood, 29 especially the relevance of the photolytic pathway. In this work, a combined 30 investigation of the photolysis and temperature-dependent OH radical reaction of 331 ...
متن کاملA QSAR for the hydroxyl radical reaction rate constant: Validation, domain of application, and prediction
A large number of anthropogenic organic chemicals are emitted into the troposphere. Reactions with the hydroxyl radical are a dominant removal pathway for most organic compounds, but experimentally determined gas-phase reaction rate constants are only available for about 750 compounds. The lack of experimental data increases the importance of applying structure-activity relationships (QSAR) to ...
متن کاملKinetics of the reaction of methyl radical with hydroxyl radical and methanol decomposition.
The CH3 + OH bimolecular reaction and the dissociation of methanol are studied theoretically at conditions relevant to combustion chemistry. Kinetics for the CH3 + OH barrierless association reaction and for the H + CH2OH and H + CH3O product channels are determined in the high-pressure limit using variable reaction coordinate transition state theory and multireference electronic structure calc...
متن کاملTemperature dependent rate coefficients for the reactions of the hydroxyl radical with the atmospheric biogenics isoprene, alpha- pinene and delta-3-carene
Pulsed laser methods for OH generation and detection were used to study atmospheric degradation reactions for three important biogenic gases: OH + isoprene (R1); OH + -pinene (R2); and OH + -3-carene (R3). Gas-phase rate coefficients were characterised by non-Arrhenius kinetics for all three reactions. For (R1), k1(241-356 K) = (1.93 0.08)10 15 exp{(466 12)/T} cmmolecule s was determined...
متن کاملThe 3-Hydroxy-2-Butanone Pathway Is Required for Pectobacterium carotovorum Pathogenesis
Pectobacterium species are necrotrophic bacterial pathogens that cause soft rot diseases in potatoes and several other crops worldwide. Gene expression data identified Pectobacterium carotovorum subsp. carotovorum budB, which encodes the α-acetolactate synthase enzyme in the 2,3-butanediol pathway, as more highly expressed in potato tubers than potato stems. This pathway is of interest because ...
