Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    der Formel:  
EMI0001.0003     
    erhält, wenn man den     2-Diazo-4.4'-dimeth-          oay-5-acetylamino-1.1'-diphenyläther    mit dem       Anilid    der     2.3-Oxynaphtoesäure    kuppelt.  Der so erhaltene     Farbstoff    bildet ein rot  violettes Pulver. Auf geeigneten Substraten,  wie zum Beispiel Baumwolle, Wolle, Kunst  seide hergestellt, färbt er diese in leuchten  den, sehr echten violetten Tönen.  



  <I>Beispiel:</I>  30,2 Teile     2-Amino-4.4'-dimethoxy-5-          acetylamino-1.1'-diphenyläther    werden wie    üblich     diazotiert    und in eine Lösung von  26,3 Teilen des     Anilids    der 2 .     3-Oxynaphtoe-          säure,    60 Teilen 30     o/oiger        Natriumhydroxyd-          lösung,    15 Teilen Soda und 2000 Teilen  Wasser eingetragen. Der gebildete     Farbstoff     fällt sofort aus. Er wird filtriert; gewaschen  und getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye of the formula:
EMI0001.0003
    obtained when the 2-diazo-4.4'-dimeth-oay-5-acetylamino-1.1'-diphenyl ether is coupled with the anilide of 2.3-oxynaphthoic acid. The dye thus obtained forms a red-violet powder. Produced on suitable substrates such as cotton, wool, artificial silk, he dyes them in bright, very real purple tones.



  <I> Example: </I> 30.2 parts of 2-amino-4,4'-dimethoxy-5-acetylamino-1,1'-diphenyl ether are diazotized as usual and poured into a solution of 26.3 parts of the anilide of the 2nd 3-Oxynaphthoic acid, 60 parts of 30% sodium hydroxide solution, 15 parts of soda and 2000 parts of water were added. The dye formed precipitates immediately. It is filtered; washed and dried.

PATENT CLAIM: Process for the production of an azo color-j substance of the formula: 0-0-OCHZ, I N = N -NHCOCH3 @ -OH OCH3 -C-N-II I 0 0 H characterized in that the 2-di-azo-4. 4'-dimethoxy - 5 - acetylamino -1. 1'- di- phenyläther mit dem Anilid der 2.3-Ogy- naphtoesäure kuppelt. Der so erhaltene Farb stoff bildet ein rotviolettes Pulver. Auf ge eigneten Substraten; wie zum Beispiel Baum wolle, Wolle; Kunstseide bergestellt, färbt er diese in leuchtenden, sehr echten violetten Tönen. 1'-diphenyl ether couples with the anilide of 2,3-ogynaphtoic acid. The dye obtained in this way forms a red-violet powder. On suitable substrates; such as cotton wool, wool; When placed on top of artificial silk, he dyes them in bright, very genuine purple tones.
