      hydrogen peroxide].

AB  - Multiphase acid-catalyzed oxidation with hydrogen peroxide (H2O2) has been 
      suggested recently to be a potential route to SOA formation, but the kinetics and 
      chemical mechanism of this process have not been well-known yet. In this work, 
      the uptake of 3-methyl-3-buten-1-ol (MBO331) into aqueous mixed solutions of 
      H2O2, and sulfuric acid (H2SO4) was performed using a rotated wetted-wall reactor 
      coupled to a VUV single-photon ionization time of flight mass spectrometer 
      (VUV-SPI-TOFMS). The reactive uptake coefficients (gamma) were acquired for the 
      first time and the reaction pathways were deduced according to products 
      information. The uptake of MBO331 into H2SO4/H2O2 was fast, resulting in gamma 
      reaching 2.52 x 10(-4)-1.05 x 10(-2) for 40%-60% H2SO4. Acetaldehyde, acetone and 
      3-methyl-3, 4-expoxybutane-1-ol were suggested as gas-phase products in this 
      process. 3-methyl-3,4-expoxybutane-1-ol can transform into polyhydroxy compounds 
      while the further reactions of the carbonyl products can occur in acidic 
      solution, which may play a role in SOA formation. Thus, the heterogeneous 
      acid-catalyzed oxidation of MBO331 with H2O2 might be a significant contributor 
      to SOA loading.
