✦ Synopsis

The decomposition of 1,3,5-trioxane has been studied in shock waves by the laser schlieren technique from 900 to 3000 K.

Dissociation was observed over the range 950-1270 K, the measurements confirming that formaldehyde is the sole product. An RRKM fit to the measured rates suggests log,&,(s-') = (15.86-50.0 kcal/mol)/2.3RTin this range. The RRKh4 model predicts rates and falloff in close agreement with previous low temperature studies, and, in agreement with the experiments, predicts large dissociation rates, kz-1 O6 s-', above 1350 K, so that this dissociation is well separated from that of its product formaldehyde up to 3000 K.
