Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man das diazo- tierte Diäthylamid der 2-Amino-4'-chlor-1,1'- diphenyläther-4-carbonsäure mit dem o-Ani- sidid der 2.3-Oxynaphthoesäure vereinigt. Der Farbstoff stellt einen roten Niederschlag dar. Auf geeigneten Substraten, wie z. B. Baumwolle, hergestellt, färbt er diesen in scharlachroten Tönen mit vortrefflichen Echt heitseigenschaften.
<I>Beispiel:</I> 31,8 Teile des Diäthylamids der 2-Amino= 4'-chlor-1,1'-diphenylätber-4-carbonsäure wer den wie üblich diazotiert und in eine Lösung von 293 Teilen des o-Anisidids der 2.3-Oxy- naphthoesäure, 50 Teilen 30 o/oiger Natrium hydroxydlösung, 15 Teilen Soda und 2000 Teilen Wasser eingetragen. Der gebildete Farbstoff fällt sofort aus. Der rote Nieder schlag wird filtriert und getrocknet.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained if the diazo-tated diethylamide of 2-amino-4'-chloro-1,1'-diphenylether-4-carboxylic acid is combined with the o-anisidide of 2,3-oxynaphthoic acid . The dye is a red precipitate. On suitable substrates, such as. B. Cotton, produced, he dyes it in scarlet tones with excellent authenticity properties.
<I> Example: </I> 31.8 parts of the diethylamide of 2-amino = 4'-chloro-1,1'-diphenyl ether-4-carboxylic acid who are diazotized as usual and dissolved in a solution of 293 parts of the o- Anisidide of 2,3-oxynaphthoic acid, 50 parts of 30% sodium hydroxide solution, 15 parts of soda and 2000 parts of water were added. The dye formed precipitates immediately. The red precipitate is filtered and dried.
