Description

  

  Verfahren zur Herstellung     eines        ehromierbaren        Monoazofarbstoffes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines ehr     omier-          baren        Monoazofarbstoffes.    Das Verfahren ist  dadurch gekennzeichnet, dass man     diazotiertes          2-Amino-plienol-4-äthylsulfon    mit     1-Butyryl-          amino-7-naphthol    vereinigt.  



  Der Chromkomplex des erhaltenen neuen  Farbstoffes stellt ein blauschwarzes Pulver  dar, (las Wolle aus neutralem Bade in grauen  Tönen von sehr guten     Nasseehtheiten    und sehr  guter     Liehtechtheit    färbt.  



       Beispiel:     20,1 Teile     2-Aminoplienyl-4-äthylstilfon     werden in 150 Teilen Wasser und 17,5 Teilen       konz.    Salzsäure     verrührt    und bei 0-5  mit  einer     Natriumnitritlösung    (entsprechend 6,9       Teilen        Natriumnitrit        100%)        diazotiert.        Die          Anschlä.mmung    der     Diazoverbindung    wird mit       Natriumbikarbonat    neutralisiert und bei 0 bis  5  in eine Lösung von 25,

  3 Teilen     1-Butyryl-          amino-7-naphthol    in 200 Teilen Wasser und  4,2 Teilen     Natriumhydroxyd    und 15 Teilen  Natriumkarbonat gegossen. Nachdem die       Farbstoffbildung    beendet ist, wird kurz auf  80  erwärmt und der Farbstoff nach Zugabe  von     Natr        iumehlorid        abfiltriert.       Der Chromkomplex des Farbstoffes kann  erhalten werden, indem man obigen Farbstoff  in 1000 Teilen Wasser mit einer Lösung aus       ehromsalicylsaurem    Ammonium (entsprechend  4,2 Teilen     Cr203)    so lange zum Sieden erhitzt,  bis die Komplexbildung beendet ist, was nach  ungefähr einer Stunde der Fall ist.

   Man iso  liert den Farbstoff nach Zugabe von     iNa-          triumchlorid    durch     Abfiltrieren.     



  Nach dem     Trocknen    stellt. er ein blau  schwarzes Pulver dar, das Wolle aus neutra  lem Bade in grauen Tönen von sehr guten       Nassechtheiten    und sehr guter Lichtechtheit  färbt. Zur Erzielung einwandfreier     Wasser-          lösliehkeit    wird mit Natriumkarbonat ver  mischt.



  Process for the preparation of an honorable monoazo dye. The subject of the present patent is a process for the production of a monoazo dye which can be modified. The process is characterized in that diazotized 2-amino-plienol-4-ethyl sulfone is combined with 1-butyryl-amino-7-naphthol.



  The chromium complex of the new dye obtained is a blue-black powder (when wool from a neutral bath is dyed in gray tones with very good wetness properties and very good lightfastness.



       Example: 20.1 parts of 2-aminoplienyl-4-äthylstilfon are concentrated in 150 parts of water and 17.5 parts. Stirred hydrochloric acid and diazotized at 0-5 with a sodium nitrite solution (corresponding to 6.9 parts of 100% sodium nitrite). The slurry of the diazo compound is neutralized with sodium bicarbonate and at 0 to 5 in a solution of 25,

  3 parts of 1-butyrylamino-7-naphthol poured into 200 parts of water and 4.2 parts of sodium hydroxide and 15 parts of sodium carbonate. After the formation of the dye has ended, the mixture is briefly heated to 80 and the dye is filtered off after the addition of sodium chloride. The chromium complex of the dye can be obtained by boiling the above dye in 1000 parts of water with a solution of Ehromsalicylsaurem ammonium (equivalent to 4.2 parts of Cr203) until the complex formation has ended, which is the case after about an hour .

   After adding sodium chloride, the dye is isolated by filtering off.



  After drying, presents. it is a blue-black powder that dyes wool from neutral baths in gray shades of very good wet fastness and very good light fastness. To achieve perfect water solubility, it is mixed with sodium carbonate.
