I, CARL ALEXANDER MARTIUS of Berlin in the Kingdom of Prussia, Empire
of Germany, Direktor of the Actiengesellschaft für Anilinfabrikation do hereby
declare the nature of this invention to be as follows:-
I have found that for the production of mixed azo-colours the diamido-combina
tions of dimethoxylediphenyle and of diethoxylediphenyle may be used in quite a
similar manner as benzidine and its homologues (diamido-ditolyle and diamido-
dixylyle).
The colouring matters are produced by combining first only one molecule of an
amine, a phenole, or a sulpho- or carbo-acid of these substances with the tetrazo-
compound obtained from the above bases and nitrous-acid, and by combining after-
wards the product thus obtained with one molecule of another substance of the
same class.
It is characteristic of this process that for the production of the colour two
different amines, phenoles, etc, must be brought into reaction..
I. EXAMPLE.
If tetrazo-diphenole-ethyle-ether obtained from 27.2 Kilogr. of the base is com-
bined with 348 Kilogr. of B-naphthole-disulpho-acid R. (soda-salt) according to
the process described in the "Berichte der deutschen chemischen Gesellschaft
Vol 17. 462, an azo compound is produced at first which is formed by the com-
bination of one molecule of each of the two components. If now this intermediate
product acts upon 246 Kilogr of soda salt of a-naphthole-mono-sulpho-acid,
instead of acting upon a second molecule of the soda salt of disulpho-acid R. a blue
colour is formed which differs favourably from the one produced from two molecules
of disulpho-acid R. by its property of being taken up more freely and completely
by the vegetable fibre.

I, CARL ALEXANDER MARTIUS of Berlin in the Kingdom of Prussia, Empire
of Germany, Direktor of the Actiengesellschaft für Anilinfabrikation, 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:
I have found that for the production of mixed azo-colours the diamido com-
binations of dimethoxyle-diphenyle and of diethoxylediphnyle may be used in a
manner similar to benzidine and its homologues (diamido-ditolyle and diamido-
dixylyle).
:
The colouring matters are produced by combining first only one molecule of an
'amine, a phenole, or a sulpho- or carbo-acid of these substances with the tetrazo-
compound obtained from the above bases and nitrous acid, and by combining
afterwards the product thus obtained with one molecule of another substance of,
the same class.
It is characteristic of this process that for the production of the colour two
different amines, phenoles, etc. must be brought into reaction.
I.-EXAMPLE.
If tetrazo-diphenole-ethyle-ether obtained from. 27.2 Kilogr: of the base is com-
bined with 348 Kilogr. of ẞ-naphthole-disulpho-acid-R. (soda-salt) according to
the process described in the "Berichte der deutschen chemischen Gesellschaft
Vol. 17. 462," an azo-compound is produced at first which is formed by the com-
bination of one molecule of each of the two components. If now, this intermediate
product acts upon 24-6 Kilogr. of soda-salt of a-naphthole-mono-sulpho-acid instead
of acting upon a second molecule of the soda-salt of disulpho-acid R, a blue colour
is formed which differs favourably from the one produced from two molecules of
disulpho-acid R by its property of being taken up more freely and completely by
the vegetable fibre.

II. EXAMPLE.
If in the process described above the a naphthole mono-sulphate of soda is
replaced by 24.5 Kilogr. of naphthionate of soda, a violet colour is formed.
In these examples, the tetrazo-diphenole-ethyle-ether employed may also be
termed the tetrazo compound of diethyloxyldiphenyle having the formula
[N N.
-
CH. (OC, H) N = N =
For this, the corresponding methyl compound,
C. Hi (OC H,),
N = N-
N NL

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is 1-
For the production of mixed azo-colours, the process substantially as herein
described, whereln tetrazo compounds of diphenole ethers or their sulpho-acids
are combined with phenoles, amines or their sulpho- or carbo-acids.
