Oxygen generator and method for starting or accelerating the oxygen production of an oxygen generating composition

A composition for generating oxygen, comprising:

• an oxygen source, an ionic liquid, a metal salt, and a basic compound;
• or
• if the ionic liquid is a basic ionic liquid or the oxygen source is basic, an oxygen source, an ionic liquid and a metal salt;
• wherein:
• the oxygen source comprises a peroxide compound;
• the ionic liquid is in a liquid state in a temperature range from −10° C. to +50° C.;
• and
• the metal salt comprises one single metal or two or more different metals, and an organic and/or an inorganic anion.

A method of starting or accelerating an oxygen production of an oxygen generating composition, the method comprising:

• providing an oxygen source comprising a peroxide compound;
• providing an ionic liquid, which in a liquid state in a temperature range from −10° C. to +50° C.;
• providing a metal salt, the metal salt having one single metal or two or more different metals, and an organic and/or an inorganic anion;
• contacting the oxygen source, the ionic liquid and the metal salt;
• and
• starting or accelerating the oxygen production by adding a basic compound to the oxygen source, the ionic liquid, and/or the metal salt.

A device for generating oxygen in a controlled manner, the device comprising:

• a reaction chamber for housing a composition for generating oxygen, the composition being a combination of constituents including of an oxygen source, an ionic liquid, and a metal salt;
• at least one dosing device housing a basic compound and being configured for introducing the basic compound into said reaction chamber, and,
• optionally, at least one dosing device housing an acidic compound and being configured for introducing the acidic compound into said reaction chamber;
• a separator device for maintaining at least one of the oxygen source, the ionic liquid, and the metal salt physically separated from remaining constituents of the composition for generating oxygen;
• a device for establishing physical contact between the oxygen source, the ionic liquid, and the metal salt;
• and
• a device for allowing oxygen to exit the reaction chamber;
• or
• a reaction chamber housing a composition for generating oxygen, the composition comprising a combination of constituents including of an oxygen source, an ionic liquid, and a metal salt;
• a device for allowing oxygen to exit the reaction chamber;
• at least one dosing device housing a basic compound and being configured for introducing the basic compound into said reaction chamber, and, optionally, at least one dosing device housing an acidic compound and being configured for introducing the acidic compound into said reaction chamber;
• wherein:
• the metal salt comprises a single metal or two or more different metals, and an organic and/or an inorganic anion;
• the oxygen source comprises a peroxide compound, the ionic liquid is in the liquid state at least in the temperature range from −10° C. to +50° C.;
• and
• a control device for controlling an oxygen production rate by selectively adding the basic compound or, optionally, the acidic compound to the composition for generating oxygen.
