Improvements in or relating to the Manufacture of a New Product
from Sugar, Ferric Oxide, and Chloride of Sodium.
I, CARL STAHLSCHMIDT of Burtscheid near Aix-la-Chapelle, in the Empire of
Germany, Professor at the Königl. Techn. Hochschule at Aix-la-Chapelle, 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 chemical combinations of iron and sugar, hitherto known, although soluble
in water, have the peculiarity of being so decomposed by acids and even neutral
salts, as to form a precipitate which is soluble only in a considerable quantity of
acids. In consequence of this the manufacture of combinations of iron and sugar
is very complicated, as, when ferric oxide is used, careful washing of the
precipitated salts is necessary if it is desired to obtain an iron sugar combination
which is perfectly soluble in water. Without removing the admixture of ferric
oxide, it has hitherto been impossible to produce a combination of iron and sugar,
perfectly soluble in water.
The present process relates to the manufacture of a combination of iron and
sugar, which, beside ferric oxide and sugar, contains considerable quantities of
chloride of sodium instead of small quantities of sodium. The process for the
manufacture of this new product is as follows: 1 litre of the solution of
perchloride of iron of the specific weight=1049, containing from 29 to 30 grammes
of peroxide of iron is diluted with litre of water; in this mixture 600 grammes
of sugar are dissolved, and the solution is then heated to 80-100° C. and about
640 c.c. of caustic lye of soda, of the specific weight 1.0985 is added which contains
in 1 litre solution about 93-95 grammes of sodium hydrate (NaOH). The
solution can then be brought to the drying chamber, or water bath.
The combination of chloride of sodium, peroxide of iron and sugar gives when
dry a shiny, black, solid mass of perfectly homogeneous structure, in which crystals
of salt are not recognisable. The chloride of sodium-peroxide of iron-sugar
combination is soluble in three times its own quantity of water. The solution
is characterised by not being precipitated either by acids (sulphuric, acetic, hydro-
chloric, tartaric, succinic or benzoic acid) or by salts (chloride of sodium, alums,
sulphate of sodium). As the hitherto known combination of ferric oxide and
sugar (ferrum oxydatum saccharatum solubile) reacts differently from the product
just described, we assume that it is a new, hitherto unknown combination of
chloride of sodium, cane-sugar and ferric oxide.
According to the relative quantities of substances used in the manufacture of
the new product, its composition ought to be Fe2O3CH220"[(NaCl)CH2]³
It will be understood that the proportion of ingredients employed, and the
temperatures given may be modified as may be found desirable.
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 ;-
1. A new product soluble in water acids and salts, consisting in the combination
of peroxide of iron (ferric oxide) chloride of sodium and cane-sugar.
2. The process of manufacturing the product formed of the combination of
peroxide of iron (ferric oxide) chloride of sodium and cane-sugar soluble in water,

perchloride of iron and about 600 grammes of sugar in
heating to 100° C. and neutralising with a solution of
described.
