I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane,
in the County of London, Consulting Engineer and Chartered Patent Agent do
hereby declare the nature of this invention to be as follows:-
This invention relates to the production of new bases and their sulpho-acids,
in connection with the invention described in the Specification No. 23310 of
4th December 1893.
My foreign correspondents have discovered that not only the chrysoïdines,
formed by the action of diazotised amines or their sulpho- and carbo-acids on the
meta-diamines, yield valuable condensation products with aldehydes, but that also
the chrysoïdines, which result when tetrazotised diamines or substitution-derivatives
of the same are combined with meta-diamines, can form analogous condensation
products when subjected in a similar manner to the action of aldehydes. According
to the origination of these new products, the characteristic nucleus, consisting of
three atoms of nitrogen and three atoms of carbon, may be contained twice in
these substances.
In preparing these new products my foreign correspondents start for instance,
from the amidoazo-compounds, obtained by combining the tetrazo-compound of a
para-diamine, such as tetrazodiphenyl and the like, with two molecules of a meta-
diamine. Or they may employ for the production of the new derivatives the
so-called mixed colouring matters, obtained by combining one of the two diazo-
groups of a tetrazotised paradiamine with one molecule of a meta-diamine and the
Moreover, the
other diazo group with one molecule of any other component.
amidoazo bodies resulting from the combination of tetrazotised naphthylene-
diamines or their suipho-acids and meta-diamines may, as my foreign correspondents
have discovered, also be used for the preparation of the new condensation-
products.
The preparation of the latter is generally carried out in an analogous manner
as has been described in the Specification No. 23310 of 1893.
Finally, my foreign correspondents have discovered, that the products resulting
in this way may equally be transformed into new mono and disulpho acids by the
action of fuming sulphuric acid as has been indicated for the products of the
Specification No. 23310 of 1893.
Deted this 22nd day of February 1894.

I, CHARLES DENTON ABEL, of No. 28 Southampton Buildings, Chancery
Lane, in the County of London, Consulting Engineer and Chartered Patent
Agent, 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 :-
This invention relates to the production of new bases and their sulpho acids,
in connection with the invention described in the Specification No. 23310 of
4th December 1893.
My foreign correspondents have discovered that not only such chrysoïdines as
are formed by the action of diazotised amines or their sulpho and carbo acids on
the meta diamines, yield valuable condensation products with aldehydes, but that
also the chrysoïdines, which result when tetrazotised diamines or substitution
derivatives of the same are combined with meta diamines, can form analogous
condensation products when subjected in a similar manner to the action of
aldehydes.
According to the origination of these new products, the characteristic nucleus
consisting of three atoms of nitrogen and three atoms of carbon, may be contained
twice in these substances.
In preparing these new products my foreign correspondents start, for instance,
from the amidoazo compounds, obtained by combining the tetrazo compound of a
para diamine, such as tetrazodiphenyl and the like, with two molecules of a meta
diamine.
Or they may employ for the production of the new derivatives the so called
mixed colouring matters, obtained by combining one of the two diazo groups of a
tetrazotised para diamine with one molecule of a meta diamine and the other diazo
group with one molecule of any other component.
Moreover, the amidoazo bodies resulting from, the combination of tetrazotised
naphthylene diamines or their sulpho acids, and meta diamines may, as my foreign
correspondents have discovered, also be used for the preparation of the new
condensation products.
The following may be given as examples for the production of these new bases.
EXAMPLE I.
21 kilos of the product obtained by the combination of tetrazodiphenyl with
meta phenylendiamine are heated on the water bath with 11 kilos. of benzaldehyde,
22 kilos. of hydrochloric acid and 50 kilos. of glacial acetic acid, until a clear
solution is formed; the reaction product is poured into water and the liquor is
filtered off in order to separate it from the insoluble impurities. By the addition
of sodium carbonate the condensation product is precipitated in the shape of a
grey precipitate, easily soluble in diluted mineral acid.
My foreign correspondents have further discovered that they may employ 'for
the production of their new products the so called mixed colouring matters,
obtained by combining one of the two diazo groups of a tetrazotised para diamine
with a meta diamine and the other diazo-group with one molecule of any other
component.

chloric acid and 50 kilos. of glacial acetic acid. The solution must be heated
for a longer time because the formation of the condensation product goes on very
slowly.
The condensation product is separated in the same manner as described in the
previous example.
Moreover, the amido azo bodies resulting from the combination of tetrazotised
naphthylene diamines or their sulpho acids and meta diamines may, as my foreign
correspondents have discovered, also be used for the preparation of the new
condensation products.
EXAMPLE III.
29-2 kilos. of the colouring matter derived from tetrazotised 2: 7-naphthylen-
diamine disulpho acid and metaphenylen diamine 11 kilos. of benzaldehyde,
36 kilos. of hydrochloric acid and a small quantity of glacial acetic acid are heated
on the water bath until the colouring matter has disappeared. On cooling, the
new product separates, and is filtered off.
The new condensation product is sparingly soluble in water, easily soluble on
addition of alkali.
Finally, my foreign correspondents have discovered that the products resulting
in this way may likewise be transformed into new mono and disulpho acids by the
action of fuming sulphuric acid as has been indicated for the products described in
the Specification No. 23310 of 1893.
All these products may also serve for the production of azo and tetrazo
colouring matters.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is -
1. The herein described manufacture of new condensation products by the
action of aldehydes of the aromatic or fat series upon such members of the class of
chrysoïdines as are derived from tetrazotised diamines or their sulpho or carbo acids
and meta diamines.
2. The transformation of the products referred to in the preceding claim into
sulphonated derivatives by the action of sulphonating agents.
3. The products manufactured as set forth in Claims 1 and 2.
