PROVISIONAL SPECIFICATION.
Improvements in the Distillation of Alcoholic Liquids.
I, JAMES LESLIE, of No. 2 Somerset Terrace, University Street, Belfast, in the
County of Antrim Chemist & Distiller, do hereby declare the nature of this invention
to be as follows, viz. :—
The generation of nascent Oxygen in the Still; and the introduction of free, or
Ozonized Oxygen, or Ozonized air; and the admixture thereof with the Alcoholic
vapour during distillation.
I do not confine myself to any special process for the production of the
Oxygen employed, but the following method is simple and answers well.
Into the pot still Barium Dioxide is introduced with the charge, and when
distillation is about to commence a continuous flow of Acid Solution is admitted
by a pipe reaching nearly to the bottom of the stil. The Oxygen thus generated
rises with the alcoholic vapour ; and being nascent readily combines with the
Fusil Oil and Alcohols present to form Aromatic Ethers. The resulting spirit is
at once mellowed and matures rapidly.
The same result is obtained in the patent still by admitting by separate pipes
into the rectifying column continuously during distillation the Barium Dioxide &
Acid Solution, or a solution of Hydrogen Dioxide previously prepared by dissolving
Barium Dioxide in Hydrochloric Acid under pressure.
Free, or Ozonized Oxygen, or Ozonized Air may be conducted by a pipe into
the body or head of the pot still, or the rectifier of the patent still, when it is
diffused through the Alcoholic vapour and is condensed with it as in the process
above described.

COMPLETE SPECIFICATION.
Improvements in the Distillation of Alcoholic Liquids.
, JAMES LESLIE of number two Somerset Terrace, University Street in the
City of Belfast and County of Antrim in Ireland Chemist and Distiller 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 mellow and more expeditiously mature alcoholic
liquids by the admixture with the alcoholic vapours, during distillation, of nascent
oxygen generated in the still or of free or ozonized oxygen or ozonized air
introduced into it.
I do not confine myself to any special process for the production of the oxygen
employed but the following method is simple and answers well. Into the pot still I
introduce Barium Dioxide along with the charge and when distillation is about to
commence I also admit a continuous flow of an acid solution by means of a pipe
reaching nearly to the bottom of the still. The oxygen which is generated by the
action of the acid solution upon the Barium Dioxide rises with the alcoholic
vapour and, being nascent, readily combines with the fusel oil and alcohols present
so as to form volatile aromatic ethers and to free the liquids from the deleterious
or fiery elements contained in them. The resulting spirit is thus at once mellowed
and rapidly matures.
The same or a similar result is obtained in the patent still by admitting, by
separate pipes, into the rectifying column, continuously during distillation, the

page_text: Barium Dioxide and Acid Solution or a Solution of Hydrogen Dioxide previously
prepared by dissolving Barium Dioxide in Hydrochloric Acid under pressure.
In like manner free or ozonized oxygen or ozonized air under pressure may
be conducted by a pipe from a reservoir into the body or head of the pot still or
into the rectifier of the patent still where it is diffused through the alcoholic
vapour and is condensed with it as in the process previously described.
↓
The quantity of oxygen or ozonized air to be employed for this purpose depends
to some extent upon the nature and requirements of the spirit operated upon and
of the taste or preference of the Distiller. For every hundred gallons of pot still
spirit to be drawn from fifty to one hundred ounces of the Barium Dioxide,
producing about ten per cent. of its weight of oxygen when treated with an
equivalent quantity of the dilute acid (preferably hydrochloric acid), may be taken
as a basis, to be increased or diminished at the discretion of the Distiller. And
for one hundred gallons of patent still or rectified spirits about half of the quantity
of Barium Dioxide above named would be sufficient.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner same is to be performed declare that what I
claim is
. 1. The use, in the distillation or rectification of alcoholic spirits, of oxygen or
ozonized air substantially in the manner and for the purposes hereinbefore
described.
2. The generation of oxygen in alcoholic spirits during the process of distilla-
tion or rectification substantially in the manner and for the purposes hereinbefore
described.
3. The introduction of free oxygen into alcoholic spirits during the process of
distillation or rectification substantially in the manner and for the purposes herein-
before described.
4. The introduction of ozonized oxygen or ozonized air into alcoholic spirits
during the process of distillation or rectification substantially in the manner and
for the purposes hereinbefore described and
5. The treatment of alcoholic spirits during the process of distillation
rectification substantially in the manner and for the purposes hereinbefore described.
