Abstract
A composition for generating oxygen includes, or is exclusively formed of, the following constituents: an oxygen source, the oxygen source being potassium superoxide, and a water-containing solution or a water-containing mixture. The water-containing solution contains such an amount of a salt or such an amount of a salt together with such an amount of an antifreeze or the water-containing mixture contains such an amount of an antifreeze, that the freezing point of the solution or of the mixture is lowered by at least 10° C. compared to the freezing point of the water. There is also described an oxygen generator and a method of generating oxygen.
Claims20
A composition for generating oxygen, comprising:
- an oxygen source, said oxygen source being potassium superoxide;
- a water-containing solution or a water-containing mixture, said water-containing solution containing a given amount of a salt or a given amount of a salt together with a given amount of an antifreeze, or said water-containing mixture containing a given amount of an antifreeze, to effectively lower a freezing point of said water-containing solution or of said water-containing by at least 10° C. compared to a freezing point of the water;
- said salt of said water-containing solution being an alkali metal hydroxide, an alkali metal hydroxide hydrate, an alkali metal chloride, an alkali metal chloride hydrate, a hydroxide with an organic cation, a hydrate of a hydroxide with an organic cation, or a mixture of at least two compounds selected from the group consisting of an alkali metal hydroxide, an alkali metal hydroxide hydrate, an alkali metal chloride, an alkali metal chloride hydrate, a hydroxide with an organic cation, and a hydrate of a hydroxide with an organic cation;
- said antifreeze including an alcohol or consisting of an alcohol.
