PROVISIONAL SPECIFICATION.
An Improved Compound or Composition for Developing Ozonized
Oxygen.
I, JOHN EDWARD PAUL MEYER, of Golden, Jefferson County, State of Colorado,
United States of America, Ph.D., M.D. Professor of Mathematics do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to furnish a ready, safe, and simple manner of
proparing ozonized oxygen in sick-rooms and elsewhere.
This has been done by the well known process of mixing concentrated sulphuric
acid with permanganate of potassium or bichromate of potassium which is not only
inconvenient but dangerous in the hands of inexperienced persons. It has also been
proposed to manufacture ozone by the reaction between permanganate of potash or
soda and an acid salt of sulphuric acid as a substitute for the sulphuric acid alone,
but the reaction of an acid salt of sulphuric acid upon an alkaline permanganate
is very feeble, oxygen being evolved very slowly and the reaction as a whole was
very incomplete as a large amount of the material would remain undecomposed. The
reason for this is very plain. The permanganic acid has a strong affinity for its
alkaline base and, as the sulphuric acid of the acid salt could at best only act as a
diluted free acid, the reaction was consequently feeble and incomplete.
My Invention consists in a compound composed of barium permanganate and an
acid salt of sulphuric acid. In this case, the sulphuric acid of the bi-sulphate
(although acting only as a diluted free acid) must, by chemical necessity, unite com-
pletely with the barium to form the insoluble barium sulphate, thus necessarily setting
free all of the permanganic acid.
To prepare my compound, I take of permanganate of barium Ba (Mn O₁) 2 (the
molecular weight of which is 375) twenty-five parts by weight and anhydrous
bisulphate of sodium Na HSU, (the molecular weight of which is 120), sixteen parts
by weight or thereabouts, preferably not less than this amount. These salts I
separately reduce to powder and then intimately mix the saine together with or
without the addition of any desired amount of an inert substance such, for instance,
as the sulphate of barium to give bulk and convenience in manipulating.
The barium permanganate, although not a common commercial article, is never-
theless a stable finely-crystallised salt which does not deliquesce and is admirably
adapted for my use.
To use this compound or composition of matter, a tablespoonful, more or less, of
the mass is put in a cup or glass and sufficient water added so that, upon mixing
and stirring, the mixture will have the consistency of a thick syrup.
This will cause
the constituent parts of the compound to chemically re-act upon each other, the acid
of the acid sulphate combining with the barium of the salt of the permanganic acid
and so perfectly setting free the permanganic acid which then spontaneously decom-
poses into hydrate dioxide of manganese and free oxygen gas which moreover is in
an ozonized condition. The odor produced will immediately shew the evolution of
ozone and after a while innumerable bubbles will be seen forming on the surface of
the mixture which will continue to gradually emit ozone for 24 hours, more or less,
and will only require occasional stirring. By using warm water or setting the
receptacle containing the mixture in a warm place, the development of the ozonized
oxygen will be hastened.
As the permanganate of barium may not be readily obtainable at all places, the
following method of manufacturing the same may be resorted to, in preparing my
compound-Dissolve hydrated baryta Ba (OH), in fusing chlorate of potash K CI O.
Then add finely pulverised dioxide of manganese Mn O,. Let the fused mass cool

page_text: and leach it out by boiling it in water whereupon manganate of barium Ba Mn O.
will be left as an insoluble green powder. This manganate of barium distribute in
water and pass a current of carbonic acid gas CO, through, by which the manganate
of barium will be changed into permanganate of barium Ba (Mn 04), according to
the formula:
2 Ba CO₂+ H, Mn O₂ + Ba (Mn O̟₁),
Ba CO, and H, Mn O, being insoluble, the liquid contains the Ba (Mn O.),
i.e. permanganate of barium in solution, together with a small quantity of bicarbonate
of barium. Decant the liquid and heat it whereupon the bicarbonate of barium is
broken up into escaping carbonic acid gas and carbonate of barium, the latter of
which settles down as insoluble. Decant now again, and the liquid will now contain
only the permanganate of barium in solution which can be produced in the dry
state by evaporation.

An Improved Compound or Composition for Developing Ozonized
Oxygen.
I, JOHN EDWARD PAUL MEYER, of Golden, Jefferson County, State of Colorado,
United States of America, Ph.D., M.D., Professor of Mathematics, 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:-
The object of my invention is to furnish a ready, safe, and simple manner of
preparing ozonized oxygen in sick-rooms and elsewhere.
This has been done by the well-known process of mixing concentrated sulphuric
acid with permanganate of potassium or bichromate of potassium, which is not only

the sulphuric acid alone, but the reaction of an acid salt of sulphuric acid upon an
alkaline permanganate is very feeble, oxygen being evolved very slowly and the

.e. permanganate of barium in solution, together with a small quantity of bicar-
bonate of barium. Decant the liquid and heat it whereupon the bicarbonate of barium
is broken up into escaping carbonic acid gas and carbonate of barium, the latter of
which settles down as insoluble. Decant now again, and the liquid will now contain
only the permanganate of barium in solution which can be produced in the dry state

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The herein-described compound or composition of matter to be used for the develop-
ment of ozonized oxygen in sick-rooms and elsewhere, the constituent parts of which
are barium permanganate and the acid salts of sulphuric acid in powdered form in
or about the proportions specified, the same to be used in connection with water, as
set forth.
