Verfahren zur Darstellung blauer Disazofarbstoffe.
Es wurde gefunden, dass wertvolle blaue Disazofarbstoffe entstehen. wenn man die Tetrazoverbindungen der Diaminodiphenyldialkylather mit 2.3 - Oxynaphtoesäurearyliden kombiniert.
Diese Farbstoffe können zur Darstellung von Pigmentfarbstoffen benutzt werden, welche von schwarzblauer Nuance, kalk- und ölecht sind. Man kann sie aber auch auf der Faser erzeugen-mit oder ohne Zusatz von Kupfersalzen, nach den bei der Darstellung von Eisfarben üblichen Arbeitsweisen - und erhalt ber Verwendung von zum Beispiel Dianisidin einerseits und 2. 3-Oxynaphtoesäureanilid andererseits grünstichig blaue Töne, welche sich vor den mit p-naphtol oder 2.3-Oxynphtoesäure erhaltenen (vergleiche D. R. Patentschriften Nr. 80409 und Nr. 86937) durch grünstichigere Nuance und wesentlich bessere Séure@chtheit auszeichnen.

Process for the preparation of blue disazo dyes.
It has been found that valuable blue disazo dyes are formed. when the tetrazo compounds of the diaminodiphenyl dialkyl ethers are combined with 2,3-oxynaphthoic acid arylides.
These dyes can be used to represent pigment dyes, which are black-blue, lime and oily. But you can also create it on the fiber - with or without the addition of copper salts, according to the usual procedures for the representation of ice colors - and get greenish blue tones by using, for example, dianisidine on the one hand and 3-oxynaphthoic anilide on the other hand those obtained with p-naphthol or 2,3-oxynphtoic acid (compare DR patents no. 80409 and no. 86937) are characterized by a more greenish shade and significantly better acidity.
Especially the acid infastness of the blue developments

effective agents are added, etch well white.

The diazo compound obtained from 244 parts of a dianist in the usual catfish

The combination can be carried out in the same way with diphenctidine; instead of 2,3-oxynaphthoic anilide, its homologues and analogs can be used, e.g. H. 2.3-Oxynaphtoesénretoluidid or 2.3-Oxynaphthoesäurechloranilid.

Diazo solution.
24 g of dianisidine base are dissolved with 21 cm3 of hydrochloric acid 21 Bé and 200 cl of boiling water and cooled, 200 g of ice and 15 cm3 of hydrochloric acid are added and 16 g of nitrite dissolved in 50 cm3 of water are allowed to flow in with constant stirring. Adjust to one liter. After printing, the goods are dried, possibly passed through the Mather plate, washed and soaped at 50 to 70. Nice greenish blue prints are obtained.
