This item is a field experiment data report of the determination of Cl -Cl 0 carbonylhtdrazine compounds in air at Birkenes in Norway. The chemical analytical method used is based on the chemical reaction between 2, 4 Dinitrophenylhydrazine and the carbonylhtdrazine compound. The chemical analysis of the corresponding carbonyl hydrazones have been performed with LC/MS (ion Trap).
The measurement data is of particular interest in the field of air pollution control strategies, tropospheric chemistry and exploration of oxidation capacity of the troposphere.
The measurement data increase the knowledge of mixing ratios and occurrence at a rural measurement site
The project result is a CD-ROM containing a word document with the LC/MSn (Ion Trap, APCI(-)) reference mass spectra of 53 different carbony-2,4-dinitrophenylhydrazone derivatives. The CD-ROM will serve as a very useful tool when working with chemical analysis of "unknown" carbonyl-2,4-dinitrophenyihydrazone derivatives and LC/MSn (Ion Trap, APCI)
This item is a graphical presentation of the comparison of measurement and modelling of carbonyl compounds and hydrocarbons at Birkenes In Norway. The numerical model - the Ozone Photochemical Trajectory incorp 1 orating a Master Chemical Mechanism - used was developed by AEA Technology. The chemical analytical measurement methods used is based on analyses with HPLCIUV. HPLCIMS and GCIMS.
These data are of particular interest in the field of air pollution control strategies, tropospheric chemistry and exploration of oxidation capacity of the troposphere.
The data brings significant increased confidence in the application of the model when it is used to define abatement strategies and policies.
This result is a LC/MSn chemical analysis method, including a fragmentation scheme for the identification of carbonyis as their 2,4-dinitrophenylhydrazone (DNPH) derivatives in ambient air. The method allows to differentiate aldehydes from ketones, branched from straight chain structures, aromatic from alpha-unsaturated carbonyls, and the identification of more substructures is possible.
This item is a data report from smog chamber experiments providing the reaction rate coefficients for the OH and NO3 radical reactions with 20 aldehydes determined at 298 K and 1013 hPa by the relative rate method. The temperature dependence of the NO3 reaction with acetaldehyde has been measured using a fast-flow discharge set-up.
The measurement data is of particular interest in the field of air pollution control strategies, tropospheric chemistry and exploration of oxidation capacity of the troposphere.
The chemical kinetics database for OH and NO3 reactions with carbonyl compounds has been augmented significantly. The new results demonstrate that the existing structure-reactivity relationship for NO3 reactions with aldehydes is inadequate.
