Aerosol Formation by Oligomerization: Kinetics and Aerosol Yields
Abstract
Methylglyoxal, along with glyoxal, is a common constituent of cloudwater. We explore the ability of both compounds to oligomerize via self-reaction during the evaporation of simulated cloud droplets. We also explore oligomerization reactions between these compounds and other nucleophiles present in clouds, such as amino acids, methylamine, and polyols. NMR kinetics data for several of these reactions, along with quantitative measurements of residual particle size, are used to determine which reactions are most likely to significantly affect aerosol formation rates during cloud processing in the atmosphere.
