ICARUS Chamber Experiment: Ziemann_20160223_pyrocatechol/nitric oxide/methyl nitrite_Hydroxyl radical_Dioctyl Sebacate_Catechol + OH/NOx_lowVOC:Ox

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 low VOC:Ox ratio.Summary: Reaction occurred in 5 minutes, was conducted at 20% lights, reacting 140 ppb of catechol. SOA mass yield was 145%, 4-nitrocatechol yield was 28%.Organization: Ziemann Lab Affiliation: University of Colorado, Boulder, Boulder, CO, USA Chamber: Janet (Chamber 1)Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Hydroxyl radical Reactants: pyrocatechol, nitric oxide, methyl nitrite Reaction Type: Photooxidation Relative Humidity: 1 Temperature: 23 Seed Name: Dioctyl Sebacate Pressure: 630 Torr
