Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
i
It is well known that hydrate of magnesium suspended in water with hydrogen
superoxide will form magnesium superoxide, and that the latter will also be pro-
duced by introducing finely powdered sodium superoxide into a solution of a
magnesium salt in water.
The superoxides so obtained are, however, very unstable, being easily decom-
posed, giving up free oxygen.
The present invention relates to a process for the production of stable magnesium
superoxide combinations, such a process not being known up to the present
time, and is as follows:-First magnesium hydrate, or basic magnesium car-
bonate or similar material is moistened to such an extent only that it still
retains a powdery form, and is. then mixed with so much sodium superoxide
powder until heat is produced indicating a chemical reaction; the heating how-
ever, must be counteracted either by cooling the vessel from the outside, or by
introducing an excess of cold hydrate of magnesium powder or basic carbonate
of sodium powder so as to avoid decomposition i.e., the generation of oxygen.
To state an example: mix 10 to 12 parts of sodium superoxide with 50 parts
of magnesium hydrate powder or of magnesium hydrocarbonate powder.
Separately moisten 50 parts of magnesium hydrate powder, or of magnesium
hydrocarbonate powder with water to the extent of half the quantity of the
sodium superoxide taken in the first mixture taking care that a very fine and
even distribution of the water in the powder is obtained. Then mix the two
sets of powder as rapidly as possible, and magnesium superoxide will be formed
under heat up to a temperature of 80° C. When the quantity of water used is
excessive the product is unstable, and when it is below the quantity required,
part of the sodium superoxide will remain unaltered which, should the product
be used suspended in water, would at once induce decomposition.
In contact with organic matter this superoxide combination acts as an antiseptic
of very great potency and value.

A communication from REINHARD WAGNITZ, Merchant, of Charitéstrasse 6,
Berlin, N.W., Germany.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
It is well known that hydrate of magnesium suspended in water with hydrogen
superoxide will form magnesium superoxide, and that the latter will also be pro-
duced by introducing finely, powdered sodium superoxide into a solution of a
magnesium salt in water.
The superoxides so obtained are, however, very unstable, being easily decom-
posed, giving up free oxygen.
The present invention relates to a process for the production of stable magnesium
superoxide combinations, such a process not being known up to the present
time, and is as follows:-First magnesium hydrate, or basic magnesium car-
bonate is moistened to such an extent only that it still retains
a powdery form, and is then mixed with SO much sodium superoxide
powder until heat is produced indicating a chemical reaction; the heating how-
ever, must be counteracted either by cooling the vessel from the outside, or by
introducing an excess of cold hydrate of magnesium powder or basic carbonate
of sodium powder so as to avoid decomposition i.e., the generation of oxygen.
To state an example: mix 10 to 12 parts of sodium superoxide with 50 parts
of magnesium hydrate powder or of magnesium hydrocarbonate powder.
Separately moisten 50 parts of magnesium hydrate powder, or of magnesium
hydrocarbonate powder with water to the extent of half the quantity of the
sodium superoxide taken in the first mixture taking care that a very fine and
even distribution of the water in the powder is obtained. Then mix the two
sets of powder as rapidly as possible, and magnesium superoxide will be formed
under heat up to a temperature of 80° C. When the quantity of water used is
excessive the product is unstable, and when it is below the quantity required,
part of the sodium superoxide will remain unaltered which, should the product
be used suspended in water, would at once induce decomposition.
In contact with organic matter this superoxide combination acts as an antiseptic
of very great potency and value.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is :-
1. A process for the production of a preparation containing magnesium super-
oxide consisting in mixing sodium superoxide powder with magnesium hydrate
powder, or basic magnesium carbonate powder containing an amount of water
sufficient to cause the necessary reaction and production of magnesium superoxide
when the substances are mixed, means being provided for preventing an undue
heating of the mixture, substantially as described.
2. A process for the production of a preparation containing magnesium super-
oxide consisting in mixing together sodium superoxide powder with magnesium
hydrate powder or with basic magnesium carbonate powder in a dry state, while

page_text: the water necessary for the decomposition of sodium superoxide is finely and
evenly mixed with another portion of magnesium hydrate powder (or basic
magnesium carbonate powder as the case may be) and the two products then
mixed together substantially as described.
3. Superoxide of magnesium produced substantially as described.
