Interaction of potassium ozonide with water vapor and carbon dioxide

1. Within the temperature interval 0 to −20°, potassium ozonide reacts vigorously with water vapor, with a complete liberation of active oxygen and the formation of potassium hydroxide dihydrate. 2. The reaction of potassium ozonide with carbon dioxide proceeds only in the presence of water vapor, through the stage of complete hydrolysis of the ozonide, followed by the formation of potassium carbonate and its crystal hydrates. The rate of evolution of oxygen is determined by the rate of diffusion of water vapor. 3. In contrast to superperoxides, in the interaction of potassium ozonide with water vapor and carbon dioxide, the formation of intermediate phases of the peroxide typeperoxide hydrates and peroxocarbonatesis not observed. 4. At −40°, the rate of the process is very low and cannot be of any practical significance.
