✦ Synopsis

The gas-phase reaction of methyl vinyl ketone with the OH radical, in the presence of NO,, was investigated at 298 ? 2 K and atmospheric pressure of air. Glycolaldehyde and methylglyoxal were observed to be the major products, with a combined yield of 0.89 ? 0.16. The sum of the yields of the two other main products, formaldehyde and peroxyacetyl nitrate, were found to be essentially unity. The product yield data for glycolaldehyde and methylglyoxal indicate that OH radical addition to the terminal carbon atom of the X = C < bond accounts for 72 * 21% of the overall reaction, with the remaining 28 ? 9% proceeding via addition to the inner carbon atom of the double bond.
