Abstract
Preliminary hydrolysis and photolysis data are presented for a suite of nitramines and nitrosamines relevant to post combustion CO2 capture using monoethanolamine solvent. Two nitramines (DMNA and MEA-NO2) and the nitrosamine NDELA were resistant to hydrolytic degradation at pH 4, 7 and 9. The nitrosamine NPz was hydrolytically stable at pH 4 and 9, but exhibited ∼30% degradation at pH 7. Nitrosamines appear highly susceptible to photolytic degradation, while nitramines are photolytically stable. The data form part of an ongoing study investigating the fate of nitrosamines and nitramines in terrestrial and aquatic environments.
