The reactions of O3 with acetylene, methylglyoxal and a series of aromatic hydrocarbons were studied at 297 ± 2°K. Rate constants k2 were obtained from the O3 decay rates in the presence of excess reactant and were determined to be (k2 × 1020 cm3 molecule-1 sec-1): acetylene 3.8 ± 0.6; methylglyoxal 0.11 ± 0.05; benzene 0.007 ± 0.004; toluene 0.015 ± 0.008; o-xylene 0.07 ± 0.02; m-xylene 0.06 ± 0.02; p-xylene 0.04 ± 0.02; 1,2,3-trimethylbenzene 0.16 + 0.04; 1,2,4-trimethylbenzene 0.13 ± 0.03; 1,3,5-trimethylbenzene 0.22 ± 0.06. The major products identified from the reaction of O3 with toluene, o-xylene and 1,3,5-trimethylbenzene were α-dicarbonyls.
