摘要

Simulation chamber experiments have been carried out at room temperature to investigate the products of the acetone +OH and acetone-d_6 +OH reactions using two photoreactors made of Teflon or Pyrex and coupled to GC-FTIR-FID analytical techniques.In the Pyrex chamber,the results demonstrated that the channel forming acetic acid is a minor oxidation route in the atmospheric acetone-h_6 +OH reaction (yield <5%),whereas a higher yield of about 20% was obtained in the case of the acetone-d_6+OH reaction,in good agreement with previous studies.Existence of a heterogeneous way of formation of acetic acid has also been identified in the Teflon photoreactor.
