Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstofes.       Es     wurde'gefunden,    dass man einen neuen       Azofarbstoff    erhält,     wenn    man das     4-Chlor-l-          oxynaphthalin-8-sulfamid    mit der     Diazover-          bindung    aus     1-Amino-2-oxynaphthalin-4-sul-          fosäure    kuppelt. Der neue Farbstoff bildet  ein schwärzliches Pulver, löst sich in Wasser  mit Bordeaux, in Natronlauge mit rotviolet  ter und in konzentrierter Schwefelsäure mit       blauer    Farbe.

   Er färbt Wolle aus saurem  Bade in stampfen Bordeaux Tönen an, wel  che beim     Nachchromieren    grünblau     werden.     <I>Beispiel:</I>  13,5 Teile     4-Chlor-l-oxynaphthalin-8-          sulfamid    werden bei 20' in eine Lösung von  27 Teilen Kalihydrat in 30 Teilen Wasser  eingetragen und solange bei dieser Tempera  tur gerührt, bis das entsprechende Kalium  salz sich gebildet hat. Hierauf wird die Mi  schung auf<B>10'</B> abgekühlt und mit 13,6 Tei  len des     Natronsalzes    der     Dia.zoverbindung     der     1-Amino-2-oxynaphthalin-4-sulfosäure       (in Form einer     50%i.gen    Paste) versetzt.

   Man  rührt weiter, bis die Kupplung vollständig  ist, indem man allmählich die Temperatur  bis 20   steigen lässt, verdünnt mit Wasser,  neutralisiert     mii    verdünnter Salzsäure und  salzt den gebildeten Farbstoff aus. .



  Process for the preparation of a new azo dye. It was found that a new azo dye is obtained when 4-chloro-l-oxynaphthalene-8-sulfamide is coupled with the diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid. The new dye forms a blackish powder, dissolves in water with Bordeaux, in caustic soda with red-violet and in concentrated sulfuric acid with blue color.

   He dyes wool from an acid bath in pounded Bordeaux tones, which turn green-blue when chromium-plating. <I> Example: </I> 13.5 parts of 4-chloro-1-oxynaphthalene-8-sulfamide are introduced at 20 'into a solution of 27 parts of potassium hydrate in 30 parts of water and stirred at this temperature until the appropriate potassium salt has formed. The mixture is then cooled to <B> 10 '</B> and mixed with 13.6 parts of the sodium salt of the dia.zo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid (in the form of a 50% i.gen Paste).

   Stirring is continued until the coupling is complete by gradually letting the temperature rise to 20, diluting with water, neutralizing with dilute hydrochloric acid and salting out the dye formed. .

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man das 4-Chlor-l-oxynapht@alin-8-sulfamid mit der Diazoverbindung aus 1-Amino-2- oxynaphthalin-4-sulfosäure kuppelt. Der neue Farbstoff bildet ein schwärzliches Pul ver, löst sich in Wasser mit Bordeaux, in Natronlauge mit rotvioletter und in konzen trierter Schwefelsäure mit blauer Farbe. Er färbt Wolle aus saurem Bade in-stumpfen Bordeaux Tönen an, welche beim #Tachchro- mieren grünblau werden. PATENT CLAIM: Process for the production of a new azo dye, characterized in that the 4-chloro-1-oxynaphth @ aline-8-sulfamide is coupled with the diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid. The new dye forms a blackish powder, dissolves in water with Bordeaux, in caustic soda with red-violet and in concentrated sulfuric acid with blue. He dyes wool from an acidic bath in dull Bordeaux tones, which turn green-blue when # tachchroming.
