for Dyeing and Printing Purposes.
I, JULIUS HAUFF of Feuerbach near Stuttgart, in the Empire of Germany, Chemist
do hereby declare the nature of this invention to be as follows:-
The invention consists in warming neutral Aluminium, Sulphocyanide or Sulpho-
cyanic acid with freshly precipitated Aluminium hydroxide, precipitated at a tempera-
ture not above 60° C.
From the Aluminium hydroxide, is dissolved in weight, up to eight times the
quantity of the Aluminium already contained in the neutral aluminium sulphocyanide.
Thus, casy soluble basic aluminium, sulphocyanide compounds are formed, which do
not decompose as easily as the neutral aluminium sulpho-cyanide salts when exposed
to heat, for instance, when the neutral salt is evaporated in the water bath to dryness,
it quickly decomposes itself, whereas the four times basic salt can be boiled and
evaporated until dryness, without decomposing, and will be easily soluble again in
water.
The less basic salts however in constancy come near to the neutral salts.
These basic aluminium sulphocyanide salts form a capital mordant for dyeing and
printing purposes.
In the same manner as described can be produced the basic sulphocyanide salts of
Iron and chromium for dyeing and printing purposes.

for Dyeing and Printing Purposes.
I JULIUS HAUFF of Feuerbach near Stuttgart, in the Empire of Germany, Chemist
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 invention consists in warming neutral Aluminium, Sulphocyanide or Sulpho-
cyanic acid with freshly precipitated aluminium hydroxide, precipitated at a tempera-
ture not above 60° C.
From the Aluminium, hydroxide is dissolved in weight, up to eight times the
quantity of the Aluminium already contained in the neutral aluminium sulpho-
cyanide.
Thus easy soluble basic aluminium, sulpho-cyanide compounds are formed, which
do not decompose as easily as the neutral aluminium sulpho-cyanide salts, when
exposed to treatment, for instance when the neutral salt is evaporated in the water
bath to dryness, it quickly decomposes itself, whereas the four times basic salt can be
boiled and evaporated until dryness, without decomposing, and will be easily soluble
again in water.
The less basic salts however in constancy come near to the neutral salts.
These basic Aluminium sulpho-cyanide salts form a capital mordaunt for dyeing and
printing purposes.
In the same manner as described can be produced the basic sulpho-cyanide salts of
Iron and Chromium for dyeing and printing purposes.
Having now particularly described and ascertained the nature of this invention and
n what manner the same is to be performed I declare that what I claim, is :—
Producing basic sulphiocyanides of Aluminium, Iron and Chromium, and employ-
ment of the same for dyeing and printing purposes, substantially as set forth.
