Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 182720.    Verfahren zur     Herstellung    eines neuen     Azofarbstof%s.       Es wurde gefunden, dass man einen     Azo-          farbstoff    erhält, wenn man     diazotierten        Äthyl-          ester    der 2 -     Ainino    - 3' -     tr-ifluormethyl    -     1,1'-          diphenylätlrer-4-carborisäure    mit     2,3-Oxy-          rraphthoesäure-2'-methoxy-5'-chloranilid    ver  einigt.

   Der neue Farbstoff bildet ein rotes,  in Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie zum Beispiel Zellulose, her  gestellt, färbt er diese in scharlachroten Tönen  mit sehr guten Echtheitseigenschaften.  



  <I>Beispiel:</I>  32,4 Teile     Äthylester    der     2-Amirro-3'-          trifluormethyl    -1,1' -     diphenyläther    - 4-     carbon-          säure    werden in üblicher Weise     diazotiert.     Die erhaltene klare     Diazolösung    wird in eine  Lösung, bestehend aus 24,7 Teilen     2,3-Oxy-          naphtoesäure-2'-methoxy-5'-Chloranilid,    50  Teilen 30     o/oiger        Natriumhydroxydlösung,    15  Teilen Natriumkarbonat und 2000 Teilen  Wasser eingetragen. Der gebildete Farbstoff  fällt sofort aus.

   Der rote Niederschlag wird  filtriert und getrocknet.    Der hier zur Verwendung gelangende       Äthylester    der     2-Amino-3'-trifluormethyl-1,1'-          dipheiryläther-4-carbonsäure    kann erhalten  werden durch Umsetzen von     1-Chlor-2-nitro-          benzol-4-carbonsäure    mit     m-Triflriormethyl-          phenolnatrium,    Verestern und     Reduzieren    des  so erhaltenen     Diphenylätherderivates.  



  <B> Additional patent </B> to main patent No. 182720. Process for the production of a new azo dye% s. It has been found that an azo dye is obtained when diazotized ethyl esters of 2 - ainino - 3 '- tr-ifluoromethyl - 1,1'-diphenyl ether-4-carboric acid with 2,3-oxyrraphthoic acid-2 '-methoxy-5'-chloranilide united.

   The new dye forms a red powder that is insoluble in water. Produced on suitable substrates such as cellulose, he dyes them in scarlet shades with very good fastness properties.



  <I> Example: </I> 32.4 parts of the ethyl ester of 2-amirro-3'-trifluoromethyl -1,1'-diphenyl ether-4-carboxylic acid are diazotized in the usual way. The clear diazo solution obtained is introduced into a solution consisting of 24.7 parts of 2,3-oxynaphthoic acid-2'-methoxy-5'-chloroanilide, 50 parts of 30% sodium hydroxide solution, 15 parts of sodium carbonate and 2000 parts of water. The dye formed precipitates immediately.

   The red precipitate is filtered and dried. The ethyl ester of 2-amino-3'-trifluoromethyl-1,1'-dipheirylether-4-carboxylic acid used here can be obtained by reacting 1-chloro-2-nitrobenzene-4-carboxylic acid with m-trifloromethyl phenol sodium, esterifying and reducing the diphenyl ether derivative thus obtained.
