Abstract
Abstract Furanaldehydes have raised environmental attention due to their large emission and high potential to generate secondary organic aerosol. In this study, the removal process of 2-furanaldehyde initiated by NO3 in gas phase was investigated by quantum chemical calculations. The overall rate constant for trans-2-furanaldehyde initiated by NO3 is 1.04 × 10−12 cm3 molecule−1 s−1 at 298 K and 1 atm. The atmospheric lifetime of 2-furanaldehyde with NO3 is estimated to be 0.53 h. This study indicates that the night-time reactions of 2-furanaldehyde with NO3 could contribute to the oxidative capacity of the atmosphere, secondary organic aerosol formation and new particle formation.
