Abstract

The kinetics and the mechanism of the reaction of silver chlorite, chlorate and Perchlorate was studied at higher temperature. The stability of the compounds increased in the order: chlorite, chlorate and Perchlorate. It was found that silver chlorite below its decomposition temperature disproportionated to chlorate and chloride and at higher temperature it exploded violently. The activation energy of disproportionation is 26 kcal. The disproportionating reaction was observed in the case of silver chlorate too, but it occurred always simultaneously with the decomposition and remained at low level. Both reactions took place in the molten phase. The activation energy of the decomposition was found to be 57 kcal. The decomposition of silver Perchlorate started in the solid but during the reaction it also melted. The value of the energy of activation is 62 kcal. Besides the kinetic measurements some physical properties of the compounds were also determined and the possible mechanism of the above reactions was discussed.
