ABSTRACT:
Calcium superoxide is prepared in high yields by spreading a quantity of calcium peroxide diperoxyhydrate on the surface of a container over an area of 18 to 300 cm.sup.2 per gram of diperoxyhydrate; positioning said container in a vacuum chamber on a support structure through which a coolant fluid can be circulated; partially evacuating said vacuum chamber, allowing the temperature of the diperoxyhydrate to reach to a level within the range of about 0.degree. to about 40.degree. C, with the assistance of an external source of heat or liquid coolant, as needed; maintaining the temperature selected for a period of time sufficient to complete the disproproriation of the diperoxyhydrate to calcium superoxide, calcium hydroxide, oxygen and water; while maintaining the partial vacuum, constantly and systematically removing the water as it is formed by sweeping the reacting material with a current of dry inert gas and/or by condensation of said water on a cold surface; backfilling the chamber with a dry inert gas; and finally recovering the calcium superoxide produced.
