science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2018 Substance: 2-acetylbenzaldehyde Other Names: ortho-acetylbenzaldehyde Formula: C9H8O2 CAS-No.: 24257-93-0 Study: uv absorption coefficients Authors: L. Wang, J. Arey, R. Atkinson Title: Kinetics and Products of Photolysis and Reaction with OH Radicals of a Series of Aromatic Carbonyl Compounds Journal/Source: Environ. Sci. Technol., 40 (17), 5465-5471, (2006); DOI: 10.1021/es061022+ Data: table, diagram Energy/Wavelength range: 205 - 400 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: 735 Torr total pressure of purified air at ~ 5% relative humidity Phase: n-hexane solution pH: Comments: The absorption coefficients for phthaldialdehyde, 2- acetylbenzaldehyde, 1,2-diacetylbenzene and phthalide are measured in n-hexane solution. Average photolysis quantum yields of 0.19 and 0.21, for phthaldialdehyde and 2-acetylbenzaldehyde in n-hexane solution were derived for the 290-400 nm wavelength region.
