Reactions of Peroxyacetyl Radicals with Reduced Sulfur Compounds

Article abstract of DOI:10.1007/BF00816843

The reaction of peroxyacetyl radicals with reduced sulfur compounds was studied at 55 deg C in N2 at 1000 mbar total pressure.The radicals were generated in equilibrium with peroxyacetyl nitrate and NO2 in large excess.The pseudo first order decay of PAN was measured in the absence and presence of several 100 ppm CH3SH, C2H5SH, n-C4H9SH, (CH3)2S and (CH3s)2.Computer simulations yielded the following rate constants of peroxyacetyl radicals with the above mentioned sulfur compounds: 3.7, 2.8, 13.0, 0.9, and 1.8*10^-16 cm³/s, respectively.An electron capturing compound of the thiols with NO2 was observed.Keywords.Reactions; PAN; Sulfur compounds.
