Goals:
Determine the SOA yield, products and molar yield of SOA products for the reaction of catechol with OH in the presence of NOx at a different NO:NO2 ratio to see how that impacts 4NC yield.
Summary:
Reaction occurred in 5 minutes, was conducted at 50% lights, reacting 29 ppb of catechol. SOA mass yield was 138%, 4-nitrocatechol yield was 27%.
