PROVISIONAL SPECIFICATION.
Process for Purifying and Decolourising Saccharine Juices and
Solutions.
We, Dr. BÉLA LACH, Chemist, of VI Gumpendorferstrasse 64, and HEINRICH
BENIES, Manufacturer, of IX Währingerstrasse 2-4, both of Vienna, in the
Empire of Austria, do hereby declare the nature of this invention to be as
follows:-
This process relates to the decolourising, and simultaneously the purifying, of
saccharine juices and solutions by freeing them of the non-saccharine matters by.
means of a product extracted from animal refuse.
In order to obtain this product, organic animal matter, or animal refuse such as
blood, flesh or hide waste, horn, hair, etc., are mixed with 5% at least of carbonate.
of potash, carbonate of soda, caustic potash, or caustic soda, in powder or in
solution, and heated or made incandescent with exclusion of air. The product thus
obtained is washed with water, then treated with muriatic acid in order to bring to
a soluble state the inorganic matter it may contain; finally it is again washed until
every trace of acid has disappeared.
The mass is then dried and powdered, and is then ready for direct use as a
purifying and decolourising agent for saccharine juices and solutions, without any
danger of acidifying the latter or decomposing the saccharine matter.
Instead of the product obtained in the manner hereinbefore described, use may
be made, after cleaning, drying and pulverizing, of the waste products of the.
manufacture of prussiate of potash.
For the purpose of purifying and decolourising saccharine juices or solutions,
from 10% to 6% of the aforesaid powder are added to them, and thoroughly:
mixed by mechanical means. The liquid thus treated is then filtered (preferably
by means of a filter press) and thus freed of the colouring and non-saccharine
matters.
In order to regenerate the purifying and decolourising product and to make it
ready for further use, the same is dried at a high temperature (about 300°
centigrade), or else washed and treated with muriatic acid, or, if preferred, the
whole series of operations herein before described are again repeated.

D01

page_text: saccharine juices and solutions by freeing them of the non-saccharine matters by
means of a product prepared from all kinds of animal refuse.
In order to obtain this product all kinds of organic animal matter, or animal
refuse such as blood, flesh-or hide-waste, horn, hair &c., are mixed with 5% at
least of carbonate of potash, carbonate of soda, caustic potash, or caustic soda, in
powder or in solution, and heated or calcined with exclusion of air. The product
thus obtained is washed with water, then treated with muriatic acid in order to
bring to a soluble state the inorganic matter it may contain, finally it is again
washed until every trace of acid has disappeared.
The mass is then dried and powdered, and is then ready for direct use as a
purifying and decolourising agent for saccharine juices and solutions, without any
danger of acidifying the latter or decomposing the saccharine matter.
Instead of the product obtained in the manner hereinbefore described, use may
be made, after cleaning, drying and pulverising of the waste products of the
manufacture of prussiate of potash (ferro-cyanide).
For the purpose of purifying and decolourising saccharine juices or solutions,
from 1% to 6% of the aforesaid powder are added to them, and thoroughly
mixed by mechanical means. The liquid thus treated is then filtered (preferably
by means of a filter-press) and thus freed of the colouring and non-saccharine
matters.
In order to regenerate the purifying and decolourising product and to make it
ready for further use, the same is dried at a high temperature (about 300°
centigrade) or else washed and treated with muriatic acid, or, if preferred, the
whole series of operations hereinbefore described are again repeated.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A process for purifying and decolourising saccharine juices and solutions by
means of products obtained by heating to incandescence, animal refuse mixed with
alkalies, or by means of the waste products resulting from the manufacture of
prussiate of potash (ferro-cyanide) which products are washed, dried, pulverised
and then added to the saccharine juices or solutions, substantially as described.
