- Abstract
- The pressure of β-FOX-7 vapors in the temperature range 140–160 °C was determined by the manometric method. The correlation dependence of logPvap on 1/T has been established, which makes it possible to estimate the value of Pvap with satisfactory accuracy in the temperature range of 100–200°C. The kinetics of the reaction in the gas phase was measured at temperatures of 200–230 °C and m/V = 10–3–10–4 g/cm3. It was found that under these conditions, in parallel with the usual monomolecular isomerization reaction into aci-form, a chain process of direct oxidation of FOX-7 by NO2 proceeds. The consequence of this reaction is a significant decrease in the activation energy observed and the appearance of rate dependence on the experimental conditions. The scheme of the main stages of the chain reaction is presented and the conditions necessary for the manifestation of this reaction are determined.
