Description
Verfahren zur Darstellung eines stickstoffhaltigen Kondensationsproduktes. Es wurde gefunden, dass man ein wert volles stickstoffhaltiges Kondensationsprodukt erhalten kann, wenn man Bz1-a-Anthrachi- nonylamirro-8-azaberrzarrthron mit einem alka lisch wirkenden Kondensationsmittel, wie Ätzalkali, Alkalialkoholat, Anilinnatrium, Natriumamid usw., behandelt.
Das Kondensationsprodukt ist neu, löst sich in konzentrierter Schwefelsäure mit blauer Farbe und färbt die pflanzliche Faser aus violetter Küpe in olivegrünen Tönen.
Beispiel Iran trägt 10 Teile sszl-a-Anthr-achinonyl- amino-8-azabenzanthron (hergestellt z. B. ans Bz1-Brom-8-azaber)zanthrorr und a-Aminoan- thrachinon) in eine 130 C heisse Schmelze aus 200 Teilen Ätzkali und 200 Teilen Äthylalkohol unter Rühren ein und erhitzt nach beendetem Eintragen solange auf 140-145<B>0</B> C, bis kein un- verändertes Ausgangsmaterial mehr nachweis bar ist. Darauf nimmt man die Schmelze mit heisserer Wasser auf, scheidet etwa in reduzierter Form vorliegende Anteile des Reaktionspro duktes durch Einblasen von Luft ab, saugt ab und wäscht neutral.
Process for the preparation of a nitrogen-containing condensation product. It has been found that a valuable nitrogen-containing condensation product can be obtained if Bz1-a-anthraquinonylamirro-8-azaberrzarrthron is treated with an alkali condensing agent such as caustic alkali, alkali metal alcoholate, aniline sodium, sodium amide, etc.
The condensation product is new, dissolves in concentrated sulfuric acid with a blue color and colors the vegetable fiber from the purple vat in olive-green tones.
Example Iran carries 10 parts of sszl-a-anthr-achinonyl-amino-8-azabenzanthrone (produced for example at Bz1-bromo-8-azaber) zanthrorr and a-aminoanthrachinone) in a melt of 200 parts at 130 C Potash and 200 parts of ethyl alcohol are added with stirring and, after the addition is complete, heated to 140-145 ° C until no more unchanged starting material can be detected. The melt is then taken up with hot water, parts of the reaction product present in reduced form are separated off by blowing in air, suctioned off and washed neutral.
