Description

  

  Verfahren zur Herstellung eines     Honoazofarbstoffes.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Herstellung  eines     blorioazofarbstoffes,    dadurch gekenn  zeichnet, dass man     2-Amino-l-phenoloctode-          cyläther        diazotiert    und mit     1-Benzoylamino-          8-oxynaphthalin-3,6-disulfonsäure    kuppelt.  Der so erhaltene Farbstoff färbt Wolle und  Seide aus saurem und neutralem Bade in  echten, blauroten Tönen.

      <I>Beispiel:</I>    39,7 Teile     2-Amino-l-phenoloctodecyl-          äther-chlorhydrat    werden mit 40 Teilen kon  zentrierter Salzsäure während einer Stunde  verrührt, mit 50 Teilen Eiswasser versetzt  und bei 5   mit einer konzentrierten     wässrigen          Lösung    von 7 Teilen     Natriumnitrit        diazotiert.     Die     Diazoniumverbindung    lässt man zu einer         ammoniakalischen    Lösung von     42,99    Teilen       1-Benzoylamino-8-oxynaphthalin-3,6-disulfon-          säure    fliessen. Die Kupplung ist in kurzer  Zeit beendet.

   Der Farbstoff wird     abfiltriert,     gepresst und getrocknet. Er bildet ein dunkles  Pulver, das sich in heissem Wasser blaurot,  in konzentrierter Schwefelsäure blau löst.



  Process for the preparation of a honoazo dye. The subject of the present Zusatzpa tentes is a process for preparing a blorioazo dye, characterized in that 2-amino-1-phenoloctodecyl ether is diazotized and coupled with 1-benzoylamino-8-oxynaphthalene-3,6-disulfonic acid. The dye obtained in this way dyes wool and silk from acidic and neutral baths in real, blue-red tones.

      <I> Example: </I> 39.7 parts of 2-amino-l-phenoloctodecyl ether chlorohydrate are stirred with 40 parts of concentrated hydrochloric acid for one hour, mixed with 50 parts of ice water and at 5 with a concentrated aqueous solution of 7 parts of sodium nitrite diazotized. The diazonium compound is allowed to flow into an ammoniacal solution of 42.99 parts of 1-benzoylamino-8-oxynaphthalene-3,6-disulfonic acid. The coupling is completed in a short time.

   The dye is filtered off, pressed and dried. It forms a dark powder that dissolves blue-red in hot water and blue in concentrated sulfuric acid.

PATENTANSPRUCH: Verfahren zur Herstellung eines NIono- azofarbstoffes, dadurch gekennzeichnet, dass man 2-Amino-l-phenoloctodecyläther diazo- tiert und mit 1-Benzoylamirio-8-oxynaphthalin- 3,6-disulfonsäure kuppelt. Der so erhaltene Farbstoff färbt Wolle und Seide aus saurem und neutralem Bade in echten, blauroten Tönen. PATENT CLAIM: Process for the production of a non-azo dye, characterized in that 2-amino-1-phenoloctodecyl ether is diazoated and coupled with 1-benzoylamirio-8-oxynaphthalene-3,6-disulfonic acid. The dye obtained in this way dyes wool and silk from acidic and neutral baths in real, blue-red tones.
