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 particle phase. The
rate constant k(OH + MEA) was determined relative to the
rate constant of the 1,3,5-trimethylbenzene reaction with OH
and was found to be (9.2 +/- 1.1) x 10(-11) cm(3)
molecule(-1) s(-1), and thus the reaction between OH
radicals and MEA proceeds a factor of 2-3 faster than
estimated by structure-activity relationship (SAR) methods.
Main uncertainty of the relative rate determination is the
unknown temporal behaviour of the loss rate of MEA to
chamber wall surfaces during the sunlit experiments.
Nucleation and growth of particles observed in the
experiments could be reproduced by the chamber model that
accounted for condensation of gaseous oxidation products,
condensation of ethanolaminium nitrate and nucleation
involving MEA and nitric acid.},
