Description

  

  Verfahren zur Herstellung     eines    neuen     Azofarbstoifes.       Es wurde gefunden, dass man einen neuen  
EMI0001.0003     
    erhält, wenn man den     Äthylester    des     2-Diazo-          4-carbonsäure-4'-chlor-1.1'-diphenyläthers    mit  dem     a-Naphtylamid    der     2.3-Oxynaphtoe-          säure    kuppelt.  



  Der so erhaltene     Farbstoff    bildet ein rotes  Pulver. Auf geeigneten Substraten, wie z. B.  Baumwolle, Wolle, Kunstseide hergestellt,  färbt es diese in leuchtenden,     sehr    echten  roten Tönen.  



  <I>Beispiel:</I>  29,1 Teile     Äthylester    des     2-Atnino-4-          carbonsäure-4'-chlor-1    .     1'-diphenyläthers    wer  den wie üblich     diazotiert    und in eine Lösung  von 31,3 Teilen des     a-Naphtylamids    der  2 .     3-Oxynaplhtoesäure,   <B>60</B> Teilen<B>80</B>      /oiger            Natriumhydroxydlösung,    15 Teilen Soda und  2000 Teilen Wasser eingetragen. Der ge  bildete Farbstoff fällt sofort aus. Er wird  filtriert, gewaschen und getrocknet.



  Process for the production of a new azo dye. It was found that you can get a new one
EMI0001.0003
    obtained when the ethyl ester of 2-diazo-4-carboxylic acid 4'-chloro-1.1'-diphenyl ether is coupled with the a-naphthylamide of 2.3-oxynaphthoic acid.



  The dye thus obtained forms a red powder. On suitable substrates, such as. B. cotton, wool, artificial silk, it dyes them in bright, very real red tones.



  <I> Example: </I> 29.1 parts of the ethyl ester of 2-atnino-4-carboxylic acid-4'-chloro-1. 1'-diphenyl ethers who diazotized as usual and in a solution of 31.3 parts of the a-naphthylamide of the 2. 3-Oxynaplhtoic acid, <B> 60 </B> parts of <B> 80 </B> /% sodium hydroxide solution, 15 parts of soda and 2000 parts of water. The dye formed precipitates out immediately. It is filtered, washed and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Azofarb- EMI0001.0021 dadurch gekennzeichnet, dass man den Athyl- ester des 2-Diazo-4-carbonsäure-4'-chlor-l.l'- diphenyläthers mit dem a-Naphtylamid der 2.3-Oxynaphtoesäure kuppelt. Der so er haltene Farbstoff bildet ein rotes Pulver. Auf geeigneten Substraten, wie z. B. Baumwolle, Wolle, Kunstseide hergestellt, färbt er diese in leuchtenden, sehr echten roten Tönen. PATENT CLAIM: Process for the production of an azo color EMI0001.0021 characterized in that the ethyl ester of 2-diazo-4-carboxylic acid 4'-chloro-1.l'-diphenyl ether is coupled with the a-naphthylamide of 2,3-oxynaphthoic acid. The dye obtained in this way forms a red powder. On suitable substrates, such as. B. cotton, wool, artificial silk, he dyes them in bright, very real red tones.
