Abstract

The effects of atmospheric aerosols on the gas-phase reactions of OH radicals with methanol, ethanol, and 1-propanol were studied. No significant difference was observed between data obtained in the presence vs. the absence of NO. Ammonium sulfate aerosols were the only aerosols that affected the relative rate of 1-propanol/p-xylene/OH system in the presence of the lower aerosol surface area. However, once the available surface area was approximately doubled, ammonium nitrate and ammonium chloride aerosols also affected the relative rate for 1-propanol vs. p-xylene. The ammonium ion was the dominant ion influencing the relative rate constant for the 1-propanol system. The influences of aerosols on the kinetics of 1-propanol/•OH reaction depended on both the composition and concentration of aerosols. This is an abstract of a paper presented at the 221st ACS National Meeting (San Diego, CA 4/1-5/2001).
