The experiments were carried out in an atmospheric simulation chamber coupled to an FTIR spectrometer and CG/MS. Since the photosensitivity of this compound is very high, the majority of these studies concern its photochemical decomposition ( Ciamician and Silber, 1901 , George and Scaiano, 1980 , Yip and Sharma, 1989 , Laimgruber et al., 2005 , Heinz et al., 2008 ). 3-NITROBENZALDEHYDE. 3-Nitrobenzaldehyde ReagentPlus ®, 99% CAS Number 99-61-6. m-nitro-benzaldehyde; 5-Nitrobenzaldehyde; Benzaldehyde, 3-nitro-; 3-nitro-benzaldehyde; 3-Formylnitrobenzene; meta-nitrobenzaldehyde; 3-NO2-benzaldehyde; Formula: C7H5NO3. Der 4-Nitrobenzaldehyd, der die höchste Symmetrie aufweist, besitzt den höchsten Schmelzpunkt. Durch deren unterschiedliche Anordnung (ortho, meta oder para) ergeben sich drei Konstitutionsisomere mit der Summenformel C7H5NO3. Compound 3-Nitrobenzaldehyde with free spectra: 10 NMR, 4 FTIR, 1 Raman, and 3 UV-Vis. Beilstein/REAXYS Number 386795 . A possible degradation products for photolysis of 2-NBA were identified.

Die Nitrobenzaldehyde bilden in der Chemie eine Stoffgruppe, die sich sowohl vom Benzaldehyd als auch vom Nitrobenzol ableitet. The UV absorption of 2-nitrobenzaldehyde (2-NBA), in gas phase, have been measured. März 2017 um 16:09 Uhr bearbeitet. This work presents an experimental study of the gas phase kinetics of 2-nitrobenzaldehyde (2-NBA) photolysis and oxidation by OH radicals. The calculated rate coefficients lead to tropospheric lifetimes of 2-NBA that are in the order of a few minutes, relative to photolysis, or a few hours, relative to oxidation by OH radicals.

Atmospheric degradation of 2- nitrobenzaldehyde: Photolysis and reaction with OH radicals. The UV spectra of 2-NBA were also measured and the experimentally determined absorption cross sections were used to estimate the atmospheric photo-dissociation constant of 2-NBA with a global quantum yield of 0.5. Die Nitrobenzaldehyde bilden in der Chemie eine Stoffgruppe, die sich sowohl vom Benzaldehyd als auch vom Nitrobenzol ableitet. Linear Formula O 2 NC 6 H 4 CHO . Molecular Weight 151.12 . The kinetics of oxidation of 2-NBA by OH radicals was investigated over the temperature range 308–352 K. The obtained rate coefficients exhibits slight negative temperature dependence and the Arrhenius expression obtained is as follows: kOH+2-NBA(T)= (7.00 ± 3.40) × 10−12exp (577 ± 156/T) cm3 molecule−1 s−1.
