Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man dianotiertes 2-Amino-1,4-diäthoxyacridon der Formel
EMI0001.0005
(Numerierung nach Ullmann, Annalen 355, Seite 312-371) mit dem Anilid der 2.3- Oxynaphthoesäure vereinigt. Der so erhaltene Farbstoff bildet ein blauviolettes Pulver. Auf geeigneten Substraten, wie z. B.
Baumwolle, hergestellt, färbt er diese in blauen Tönen von vorzüglichen Eehtheitseigenschaften.
<I>Beispiel:</I> 31,8 Teile des 2-Amino-1,4-diäthoxyacri- dons der Formel
EMI0001.0015
(Numerierung nach Ullmann, Annalen 355, Seite 312-371) werden wie üblich diano tiert und in eine Lösung von 26,3 Teilen 2. 3-Oxynaphthoesäureanilid, 50 Teilen 30 /o iger Natriumhydroxydlösung, 15 Teilen Na triumkarbonat und 2000 Teilen Wasser ein getragen. Der gebildete Farbstoff fällt sofort aus. Der blauviolette Niederschlag wird fil triert und getrocknet.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 2-amino-1,4-diethoxyacridone of the formula
EMI0001.0005
(Numbering according to Ullmann, Annalen 355, pages 312-371) combined with the anilide of 2,3-oxynaphthoic acid. The dye thus obtained forms a blue-violet powder. On suitable substrates, such as. B.
Cotton, produced, he dyes them in blue tones of excellent fastness properties.
<I> Example: </I> 31.8 parts of the 2-amino-1,4-diethoxyacridone of the formula
EMI0001.0015
(Numbering according to Ullmann, Annalen 355, pages 312-371) are diano benefits as usual and in a solution of 26.3 parts of 2. 3-oxynaphthoic anilide, 50 parts of 30% sodium hydroxide solution, 15 parts of sodium carbonate and 2000 parts of water carried. The dye formed precipitates immediately. The blue-violet precipitate is filtered off and dried.
