Abstract

The rate coefficient for reaction of OH with CH₂=C(CH₃)C(O)OONO₂ (MPAN, peroxymethacrylic nitric anhydride), k₃, has been determined using a relative rate technique. Consistent results were obtained with ethene and propene as the reference compound, and a rate coefficient of k₃=(3.2±0.8)×10^-11cm³ molecule^-1s^-1 is reported at 275±3K. This value is about a factor of eight larger than the only previous report. A brief investigation of the products of the OH-initiated oxidation of MPAN and methacrylic acid (CH₂=C(CH₃)COOH, an impurity in the MPAN sample but also a structural analog of MPAN) is also reported. Major products obtained in the case of methacrylic acid were CH₂O and pyruvic acid (CH₃C(O)C(O)OH), while CH₂O, CO₂, and possibly hydroxyacetone are observed in the case of MPAN. The atmospheric implications of the results are briefly discussed.
