TL;DR: The possibility of the formation of a new perperoxide magnesium peroxide Mg (O2)2 at −85 to −65° in the reaction of ozone, dissolved in Freon-12, with a suspended in the same medium, was demonstrated in this article.
Abstract: 1. The possibility of the formation of a new perperoxide magnesium perperoxide Mg (O2)2 at −85 to −65° in the reaction of ozone, dissolved in Freon-12, with magnesium peroxide, suspended in the same medium, was demonstrated. 2. Preparations were isolated containing ∼60% Mg(O2)2. The individuality of magnesium perperoxide was confirmed by the EPR method. The limit of its thermal stability −35 to −29° was established by the method of differential thermal analysis.

Journal ArticleDOI
TL;DR: The limits of thermal stability of magnesium peroxide preparations containing up to 75% MgO2 were determined by the method of differential thermal analysis as mentioned in this paper, and it was shown by an interpretation of the thermograms that these preparations release the bulk of the water of the adsorbed mother liquor at 110° and are entirely dehydrated at 260°.
Abstract: 1. The limits of thermal stability of preparations containing up to 75% MgO2 were determined by the method of differential thermal analysis. 2. It was shown by an interpretation of the thermograms that these preparations release the bulk of the water of the adsorbed mother liquor at 110° and are entirely dehydrated at 260°. In this case there is a partial decomposition of MgO2 with evolution of oxygen and the formation of Mg(OH)2. 3. The mixture of MgO2 and Mg(OH)2 formed decomposes exothermic ally within the range 360–375°, liberating oxygen and forming MgO. The following reactions are responsible for the exothermicity of the effect on the heating curves of magnesium peroxide preparations: MgO2+2H2O→Mg(OH)2+H2O2, H2O2→H2O+1/2 O2.
