& Co., Patent Agents, Southampton Buildings, London, for an Invention of
"IMPROVED PROCESSES FOR REFINING OR PURIFYING ALCOHOL OR ALCOHOLIC
LIQUIDS, FATTY OR OILY MATTERS, AND WAX, AND FOR REGENERATING

PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents on the 18th August 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVED PROCESSES FOR REFINING OR
PURIFYING ALCOHOL OR ALCOHOLIC LIQUIDS, FATTY OR OILY MATTERS, AND
WAX, AND FOR REGENERATING MATERIALS EMPLOYED IN SUCH PROCESSES."
[A communication from abroad by Simon Roessler, of Troppau, Austria.]
This Invention relates to processes for removing from alcohol or alcoholic liquids,
also from animal fat of various kinds or mineral oil (hydro-carbons) and from vege-
table wax, such as Japan-wax, myrica-wax, carnauba, and the like, the matters which
impart to them the objectionable color and odour which they frequently possess.
The said Invention further relates to the refining and regenerating of some of the
material used in such processes.
According to the said Invention the removal of the objectionable color and
odour from the spirits, substances, or materials named is effected by causing the
alcohol or alcoholic liquids and the fat or other substance to act upon each other,
as hereinafter set forth.
When the refining of brandy or other alcoholic liquid or alcohol is the chief object
in view I proceed as follows, that is to say:-
To the alcohol, brandy, spirits of wine (ethylic alcohol), or the like, which it is
desired to render inodorous and colorless, and at the same time to free from all
those alcoholic combinations that are ordinarily termed "fusel-oil," I add either
during the process of manufacture thereof or after manufacture some fat, oil, or
vegetable wax, or a mixture thereof, and then distil such brandy or other liquid in
the usual manner, or extract it by mechanical methods.

page_text: The alcoholic liquids commonly known as "fusel-oil" (such as propylic, butylic,
or amylic alcohol, or the like) are according to this Invention freed from their
particular disagreeable smell and are made colorless, and at the same time
concentrated by distilling them (repeatedly if necessary) together with fat oil, or
vegetable wax, or a mixture thereof. This distillation is effected on an open
fire or by steam, either under the ordinary atmospheric pressure or under a greater
pressure and at a suitable temperature.
When the chief object is to refine fat, mineral oil, or vegetable wax, I proceed
according to this Invention as follows, that is to say:-
The fat, oil, or the like, which is to be refined is heated either upon an open
fire or in closed vessels by means of steam, which may or may not be under
pressure. Raw or refined fusel-oil is added to the fat, oil, or the like, or the deposit
remaining in the stills or distilleries may be employed instead of the fusel-oil.
By these means the substances which principally impart to the two main-products
their color and characteristic unpleasant smell are amalgamated and precipitated,
and the sediment thus formed having been discharged the fusel-oil is partly
eliminated from the fat, oil, or the like, under treatment, which is then refined by
means of animal charcoal, or it is first distilled and then bleached by means of
the animal charcoal, and finally filtered as usual.
The regeneration of the materials used in the filtering I effect according to my
Invention as follows, that is to say :-
The animal charcoal used in the bleaching, and filtering contains fatty matters
absorbed by it during the process. These fatty matters I extract by the addition
of fusel-oil. I continue to add fusel-oil until the last trace of fat, together with the
coloring substances absorbed at the same time, has been completely eliminated.
Thus not only is the fat retained by the charcoal regained, but the animal charcoal
used, whether for bleaching or filtering, is also regenerated, that is to say, rendered
fit for renewed application.

by the said William Robert Lake in the Great Seal Patent Office on the

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVED PROCESSES FOR REFINING OR
PURIFYING ALCOHOL OR ALCOHOLIC LIQUIDS, FATTY OR OILY MATTERS, AND
WAX, AND FOR REGENERATING MATERIALS EMPLOYED IN SUCH PROCESSES."
A communication from abroad by Simon Roessler, of Troppau, Austria.
This Invention relates to processes for treating alcohol, mineral fats (hydro-
carbons), all kinds of vegetable wax, such as Japan-wax, myrica-wax, carnauba, and
the like, and animal fats to refine the same; all of these fats, whether raw or
partially refined, solid or liquid, and alcohols are refined by the reaction between
them when mixed, and are freed from those admixtures which impart to them
their disagreeable smell and color as follows :-
When the refining of brandy or other alcoholic liquid or alcohol is the chief
object in view, I proceed as follows, that is to say :-
To the brandy, spirits of wine (ethylic alcohol), or the like, which it is desired
to render inodorous and colorless, and at the same time to free from all those
alcoholic substances that are ordinarily termed "fusel-oil," I add either during the
process of manufacture thereof or after manufacture soine fat, oil, or vegetable wax,
or a mixture thereof, and then distil such brandy or other liquid in the usual
manner, or extract it by mechanical methods.
The alcoholic liquids commonly known as "fusel-oil," such as propylic, butylic,
or amylic alcohol, or the like, are according to this Invention freed from their
particular disagreeable smell and are made colorless, and at the same time
concentrated, by distilling them (repeatedly if necessary) together with fat, oil, or
vegetable wax, or a mixture thereof. This distillation is effected on an open fire
or by steam, either at the ordinary atmospheric pressure or at a greater pressure
and at a suitable temperature.
When the chief object is to refine fat, under which term I include mineral
oil and vegetable wax, I proceed according to this Invention as follows, that is
to say :-
The fat, oil, or the like, which is to be refined is heated upon an open fire or in
closed vessels by means of steam, either at the ordinary atmospheric pressure or
at a higher pressure.
Raw or refined fusel-oil is added to the fat, oil, or the
like, or the deposit remaining in the stills of distilleries may be employed instead
of the fusel-oil. By these means the substances which principally impart to the
two main-ingredients their color and characteristic unpleasant smell are amalgamated
and precipitated, and the sediment thus formed having been discharged the fusel-
oil is partly eliminated from the fatty matters thus treated, which are then refined
by means of animal charcoal, or they are first distilled and then bleached by means
of the animal charcoal, and finally filtered as usual.
The regeneration of the materials used in the filtering is effected according to
my Invention as follows, that is to say-The animal charcoal used in the
bleaching and filtering contains fatty matters absorbed by it during the process.
These fatty matters are extracted by the addition of fusel-oil. I continue to add
fusel-oil until the last trace of fat, together with the coloring substances absorbed
at the same time, has been completely eliminated. Thus not only is the fat
retained by the charcoal recovered, but the animal charcoal used, whether for
bleaching or filtering, is also regenerated, that is to say, rendered fit for renewed
application.

page_text: Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it under-
stood that I claim,-
First. The process above set forth for producing by means of the fatty matters,
hereinabove specified and in the manner set forth, brandy or ethylic alcohol free
from the odour of fusel oil and colorless.
Second. The process above set forth for producing, odourless and colourless
alcoholic substances of the kind known as fusel-oils.
Third. The process above set forth for completely refining raw or partially
refined fatty-matters by treatment with raw or refined fusel-oils and subsequent
filtering.
Fourth. The process above set forth for regenerating the filtering material used
for filtering fats by washing with fusel-oil.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Eighteenth day of February, in the year of our Lord
One thousand eight hundred and eighty one.
