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. Anilin, erhält,  wenn man auf ein Hol.     Cyanurchlorid    in be  liebiger     Reihenfölga    ein Hol.     1.8-Amino-          naphthol-3        #        6-disulfosäure    und ein Hol. Ani  lin einwirken 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     Mol.        Cyanurchlorid,    einem Hol. 1 .     8-          Aminonaphthol-3.6-disulfosäure    und einem  Hol. Anilin bildet ein in Wasser leicht lös  liches, farbloses, kristallinisches Pulver. Es  enthält noch ein     reaktionsfähires    Chloratom  und stellt ein wertvolles Ausgangsmaterial  zur Herstellung von Farbstoffen dar.  



  <I>Beispiel:</I>  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 saure  Lösung wird sehr vorsichtig fast genau neu  tralisiert und hierauf nach -Zusatz von 30       Teilen    kristallisiertem     Natriumacetat,    mit  einer Lösung von 12 Teilen     Anilinchlor-          hydrat    versetzt.

   Man rührt, bis das     'Anilin     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. Aniline, obtained when one on a haul. Cyanuric chloride in any order. 1,8-amino-naphthol-3 # 6-disulfonic acid and a hol. Let aniline act.



  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 of one mole of cyanuric chloride, one hol. 1 . 8-aminonaphthol-3,6-disulfonic acid and a hol. Aniline 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.



  <I> Example: </I> 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 are gone. The acidic solution thus obtained is very carefully neutralized almost exactly and then, after addition of 30 parts of crystallized sodium acetate, a solution of 12 parts of aniline chlorohydrate is added.

   The mixture is stirred until the aniline has almost disappeared, salted out, filtered and dried.
