Study of OH-initiated degradation of 2-aminoethanol

Abstract: Abstract. The degradation of 2-aminoethanol (MEA) by the hydroxyl radical (OH) was studied in the European Photoreactor (EUPHORE), a large outdoor environmental chamber. High-Temperature Proton-Transfer-Reaction Mass Spectrometry (HT-PTR-MS) and Fast Fourier Transform Infrared (FT-IR) were used to follow concentrations of reactants in the gas phase. Aerosol mass concentrations were tracked with Aerosol Mass Spectrometry (AMS). The chamber aerosol model MAFOR was applied to quantify losses of MEA to the particl… Show more

“…The main aim of the present study is to investigate the atmospheric product spectrum from MEA-oxidation, including nitrosamines and nitramines but also carbonylic compounds, under different environmental conditions using the detailed MEA photooxidation scheme proposed in the work by Karl et al (2012). The WRF--EMEP model framework included a simplified treatment of the OH-initiated oxidation of MEA intended for prediction of nitrosamines and nitramines, with limited detail on carbonylic products forming upon H-abstraction at the -CH 2 and -CH 2 OH groups of MEA.…”
