Abstract

The formation yields of acrolein, 1,2-epoxy-3-butene and OH radicals have been measured from reaction of ozone with 1,3-butadiene at room temperatureand atmosphere pressure. 1,3,5-Trimethyl benzene was added to scavenge OH radicals in measurements of product yields. In separate experiments, small quantities of 1,3,5-trimethyl benzene were added as a tracer for OH. Formation yields of acrolein of (52 +/- 7)%, 1,2-epoxy-3-butene of (3.1 +/- 0.5)%and OH radicals of (13 +/- 3)% were observed, In addition, the rate coefficient of the gas-phase reaction of ozone with 1,2-epoxy-3-butene was measured both directly and relative to propane, finding an average of (1.6 +/- 0.4) x 10(-18) cm(3) molecule(-1) s(-1), respectively, at 296 +/- 2 K. The results are briefly discussed in terms of the effect of atmospheric processing on the toxicity of 1,3-butadiene. (C) 1999 Elsevier Science Ltd. All rights reserved.
