Abstract

Goals: Oxidation product & SOA formation study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) ozonolysis under humid (50% RH) conditions. Summary: 1,2-DHI and ammonium sulfate seed aerosol were injected into a humidified chamber and the bag was mixed and allowed to equilibrate. Ozone was injected over the course of 2 minutes with pulses of mixing air. Ozonolysis and SOA formation were allowed to continue for ~5.5 hours before shutdown. At ~4:15 pm an MSMS scan of m/z 169 was performed to help identify this product. Organization: Nguyen Group Lab Affiliation: UC Davis Chamber: Tran's big bag of air Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Ozone Reactants: 2-methylbut-3-ene-1,2-diol, OZONE Reaction Type: Dark oxidation Relative Humidity: 56 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755
