Inhibition of the photoinduced ignition of chloromethane–chlorine mixtures by oxygen

详细

The introduction of small amounts of oxygen inhibits the photoinduced ignition of chloromethane–chlorine mixtures. This is accompanied by an increase in the induction period and a decrease in the degree of heating of the reaction mixture. After the consumption of the entire inhibitor, the photochlorination reaction takes place again in the thermal explosion regime but with a lower degree of heating. In the dependence of the mixture temperature on the oxygen concentration, criticality is not pronounced. With an increasing concentration of oxygen, its effect on the induction period weakens.
