The existence of two regimes of chain combustion is predicted, the phenomenon of explosion with a chain mechanism is explained, and the condition for the transition of combustion to this regime is formulated. The abrupt changes in the kinetic curves during the transition of combustion to this regime are illustrated and explained. The results of an experimental study of the transition from combustion to explosion are presented; it is found out that the ignition peninsulas, which are presented in courses and monographs on chemical kinetics as kinetically homogeneous regions, actually consist of two regions that are different in all reaction characteristics: the combustion region and the explosion region. Experimental evidence is given of the chain nature of combustion in an explosion under conditions of cumulation and control of such an explosion by means of inhibitors.
期刊介绍：
Kinetics and Catalysis Russian is a periodical that publishes theoretical and experimental works on homogeneous and heterogeneous kinetics and catalysis. Other topics include the mechanism and kinetics of noncatalytic processes in gaseous, liquid, and solid phases, quantum chemical calculations in kinetics and catalysis, methods of studying catalytic processes and catalysts, the chemistry of catalysts and adsorbent surfaces, the structure and physicochemical properties of catalysts, preparation and poisoning of catalysts, macrokinetics, and computer simulations in catalysis. The journal also publishes review articles on contemporary problems in kinetics and catalysis. The journal welcomes manuscripts from all countries in the English or Russian language.
