Atmospheric Chemistry of Amines and Related Compounds

Goal of the Project:
-    (1) To identify and quantify all primary products resulting from the OH initiated photo-oxidation of selected amines under natural conditions, and to characterize and quantify aerosol formation during the gas phase degradation of amines.
-    (2) To update and develop quantum-chemistry based gas-phase photo-oxidation mechanisms for amines and their atmospheric degradation products for subsequent implementation in atmospheric chemistry and dispersion models.
Results to date:
-    Extensive data sets have been obtained from photo-oxidation studies in the EUPHORE chamber. The following compounds were investigated: tert-butyl amine, 2-methyl-2-amino propanol (AMP), piperazine, N-nitro-piperazine, N-nitroso-piperazine, piperidine, morpholine, 1,2-diamino-ethane, 1,3-diamino-propane, imidazole, formamide and N-methyl-methanimine.
-    Extensive data sets have been obtained from photo-oxidation studies of amine degradation products in the Oslo chamber. The following were investigated: N-methyl-methanimine, N-ethyl-methanimine, isocyanomethane.
-    Detailed quantum chemistry based photo-oxidation mechanisms have been produced for all the abovementioned compounds.
-    A research paper “Experimental and Theoretical study of the OH-initiated photo-oxidation of Formamide” has been published in J. Phys. Chem. A. 2016, 120, 1222−1230.
-    An extended abstract “Atmospheric chemistry of tert-butylamine and AMP“ is in preparation for the 13th International Conference on Greenhouse Gas Control Technologies, GHGT-13, 14-18 November 2016, Lausanne, Switzerland.
-    Project results were presented in an Invited lecture “Atmospheric chemistry of reduced nitrogen compounds” at the 13th Informal Conference on Atmospheric and Molecular Science, Lund, June 13-14 2016.
