ICARUS Chamber Experiment: Ziemann_20071120_3,4-Diethylhexane/Methyl nitrite/Nitric oxide_Hydroxyl radical_DOS
Listed in National Center for Atmospheric Research
Goals: Determine SOA yield of OH radical oxidation of the VOC
Description
Summary
Alkanes were reacted with OH radicals in the presence of NOx in a 5900 L PTFE environmental chamber filled with clean, dry air (< 5 ppbv hydrocarbons, < 1% RH) at 25 C and atmospheric pressure. The reaction mixture contained 200 - 400 ug/m^3 of dioctyl sebacate (DOS) seed particles added from an evaporation condensation aerosol generator and 1 (0.5 heptadecane), 10, and 10 ppmv alkane, methyl nitrite, and NO. Reactions were initiated by turning on blacklights to form OH radicals by methyl nitrite photolysis.

The average OH radical concentration for 60 minutes of reaction was 3 x 107 cm^-3 , and 50-85% of the alkane reacted. Organization: Ziemann Lab Affiliation: University of Colorado, Boulder, Boulder, CO, USA Chamber: UC Riverside (APRC) Experiment Category: Gas phase chemical reaction, Photolysis, any phase, Aerosol formation, Aerosol aging Oxidant: Hydroxyl radical Reactants: 3,4-Diethylhexane, Methyl nitrite, Nitric oxide Reaction Type: Photooxidation Relative Humidity: 1 Temperature: 25 Seed Name: DOS Pressure: 740 Torr
