Experiment Set
Resorcinol
Goals
Determine the gas-phase and particle-phase reaction products as well as SOA yield of resorcinol + NO3 in the presence of NOx.
Summary
400 ppb of resorcinol was added to 1 ppm of N2O5 present in the chamber. N2O5 thermally dissociated to NO3 + NO2, and NO3 reacted with resorcinol. SOA Yield was 11% assuming all resorcinol reacted.Experiment Details

Time format and units:
Description:
Identifying gas-phase and particle-phase products and secondary organic aerosol yields of reactions of 1,3-benzenediol (resorcinol). Goals were to determine the impact of isomers on chemistry (compared to that of catechol) and effects in wildfires. Additionally, to determine method of investigating semi-volatile compounds that would otherwise partition entirely to chamber walls.
