Description

  

      Zusatzpatent    zum Hauptpatent Nr. 175030.    Verfahren zur Herstellung eines neuen     Azofarbstoff'es.       Es wurde gefunden, dass man einen neuen     Azofarbstoff    der Formel  
EMI0001.0004     
    erhält, wenn man den     2-Diazo-5-acetyamino-          4.4'-dichlor-1.1'-dipheriyläther    mit dem     2-          Naphthylamid    der     2.3-Oxynaphthoesäure     kuppelt.  



  Der so erhaltene     Farbstoff    bildet ein  bordeauxrotes Pulver. Auf geeigneten Sub  straten, wie zum Beispiel Baumwolle, Wolle;  Kunstseide, hergestellt, färbt er diese in leuch  tenden, sehr echten bordeauxroten Tönen.  



  <I>Beispiel:</I>  31,1 Teile 2-Amino-5-acetylamino-4-4'-         dichlor-1.1'-diphenyläther    werden wie üblich       diazotiert    und in eine Lösung von 31,3 Teilen  des     2-Naphthylamids    der     2.3-Oxynaphthoe-          säure,    60 Teilen 30     o/oiger        Natriumhydroxyd-          lösung,    15 Teilen kristallisiertes Natrium  acetat und 2000 Teilen Wasser eingetragen.  Der gebildete Farbstoff fällt sofort aus. Er  wird filtriert, gewaschen und getrocknet.



      Additional patent to main patent no. 175030. Process for the production of a new azo dye. It has been found that a new azo dye of the formula
EMI0001.0004
    obtained when the 2-diazo-5-acetyamino-4.4'-dichloro-1.1'-dipheriyl ether is coupled with the 2-naphthylamide of 2.3-oxynaphthoic acid.



  The dye obtained in this way forms a burgundy powder. Straten on suitable substrates, such as cotton, wool; When he produces artificial silk, he dyes them in brilliant, very genuine burgundy red tones.



  <I> Example: </I> 31.1 parts of 2-amino-5-acetylamino-4-4'-dichloro-1.1'-diphenyl ether are diazotized as usual and dissolved in a solution of 31.3 parts of the 2-naphthylamide 2,3-Oxynaphthoic acid, 60 parts of 30% sodium hydroxide solution, 15 parts of crystallized sodium acetate and 2000 parts of water were added. The dye formed precipitates immediately. It is filtered, washed and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Azofarb- stoffes der Formel EMI0002.0001 dadurch gekennzeichnet, dass man den 2-Diazo- 5-acetylamino-4. 4'-dichlor-1.1'-diphenyläther mit dem 2-Naphthylamid der 2.3-Oxynaph- thoesäure kuppelt. Der so erhaltene Farbstoff bildet ein bor deauxrotes Pulver. Auf geeigneten Substraten, wie zum Beispiel Baumwolle, Wolle, Kunst seide, hergestellt, färbt er diese in leuchten den, sehr echten bordeauxroten Tönen. PATENT CLAIM: Process for the production of an azo dye of the formula EMI0002.0001 characterized in that the 2-diazo-5-acetylamino-4. 4'-dichloro-1.1'-diphenyl ether couples with the 2-naphthylamide of 2,3-oxynaphthoic acid. The dye thus obtained forms a boron deaux red powder. Produced on suitable substrates such as cotton, wool, artificial silk, he dyes them in bright, very real burgundy shades.
