Abstract

The products and mechanism of the gas-phase reaction of NO3 radicals with but-2-yne in purified air have been investigated by FTIR spectroscopy. The experiments were carried out at 298±3 K and 760±5 Torr in a 250 l stainless-steel reactor in which NO3 was generated by the thermal dissociation of N2O5. Experiments with 15NO3 were also performed. Products include butadione, peroxyacetyl nitrate, ketene and acetic acid. Ketene was observed to ...
