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.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man das diazotierte Diäthylamid der 2-Amino- 4'-chlor-1,1'-diphenyläther-4-carbonsäure mit dem o-Anisidid der 2.3-Oxynaphthoesäure vereinigt. Der Farbstoff stellt einen roten Niederschlag dar. Auf geeigneten Substraten, wie z. B. Baumwolle, hergestellt, färbt er diese in scharlachroten Tönen mit vortreff lichen Echtheitseigenschaften. Claim: Process for the preparation of a new azo dye, characterized in that the diazotized 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 them in scarlet tones with excellent fastness properties.
