Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem Hol.     Cyanurchlorid     mit einem Hol. 1     #        8-Aminonaphthol-3    .     6-di-          sulfosäure    und einem Hol.     1-Amino-4-acetyl-          aminobenzol,    erhält, wenn man auf ein Hol.

         Cyanurchlorid    in beliebiger Reihenfolge ein  Hol. 1 .     8-Aminonaphthol-3    .     6-disulfosäure     und ein Hol.     1-Amino-4-acetylaminobenzol          ein-,virken    lässt.  



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in einem geeig  neten Verdünnungsmittel durchgeführt, und  es wurde gefunden, dass als solches Wasser  in überraschender Weise sehr gut geeignet ist.  Das sekundäre Kondensationsprodukt aus  einem Hol.     Cyanurchlorid,    einem Hol. 1. 8  Aminonaphthol-3.6-disulfosäure und einem  Hol.     1-Air:no-4-acetylaminbenzol    bildet ein  in Wasser leicht lösliches, farbloses, kristal  linisches Pulver. Es enthält noch ein reak  tionsfähiges Chloratom und stellt ein wert  volles Ausgangsmaterial zur Herstellung von  Farbstoffen dar.

           Beispiel:     31,9 Teile     1.8-Aminonaphthol-3.6-di-          sulfosäure    werden in 500 Teilen Wasser unter  Zusatz von 13,3 Teilen 30     %iger    Natron  lauge gelöst,     mit    18,5 Teilen     Cyanurchlorid     versetzt und     gerührt,    bis die Komponenten  verschwunden sind. Die so erhaltene säure  Lösung wird sehr vorsichtig fast genau neu  tralisiert und hierauf nach Zusatz von 30  Teilen kristallisiertem     Natriumacetat,    mit  einer Lösung von 17,2 Teilen salzsaurem       1-Amino-4-acetylaminobenzol    versetzt.

   Man  rührt, bis das     1-Amino-4-acetylaminobenzol          beinahe    verschwunden ist, salzt aus, filtriert  und trocknet.



  Process for the production of a new intermediate product. It was found that a new intermediate product, the secondary condensation product of a Hol. Cyanuric chloride with a hol. 1 # 8-aminonaphthol-3. 6-disulfonic acid and a hol. 1-Amino-4-acetyl-aminobenzene, obtained when one on a Hol.

         Cyanuric chloride in any order a haul. 1 . 8-aminonaphthol-3. 6-disulfonic acid and a hol. 1-Amino-4-acetylaminobenzene, virken.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that, surprisingly, water is very suitable as such. The secondary condensation product from a haul. Cyanuric chloride, a hol. 1. 8 aminonaphthol-3,6-disulfonic acid and a hol. 1-Air: no-4-acetylaminobenzene forms a colorless, crystalline powder that is easily soluble in water. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

           Example: 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid are dissolved in 500 parts of water with the addition of 13.3 parts of 30% sodium hydroxide solution, mixed with 18.5 parts of cyanuric chloride and stirred until the components have disappeared. The acid solution obtained in this way is very carefully neutralized almost exactly and then, after adding 30 parts of crystallized sodium acetate, a solution of 17.2 parts of 1-amino-4-acetylaminobenzene hydrochloric acid is added.

   The mixture is stirred until the 1-amino-4-acetylaminobenzene has almost disappeared, salted out, filtered and dried.
