Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes.       Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Konden  sationsprodukt von einem     blol.        Cyanurchlorid     mit zwei     31o1.    2 - 8 -     Aminonaphthol    - 6     -sul-          fosäu-re,    erhält, wenn man auf ein     Mol.          Cyanurchlorid    zwei     Mol.    2     #    8 -     Aminonaph-          thol-6-sulfosäure    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    mit zwei     Mol.     2 -     8-Aminonaphthol-6-sulfosäure    bildet ein  in Wasser leicht lösliches, kristallinisches,  fast farbloses Pulver. Es enthält noch ein  reaktionsfähiges Chloratom und stellt ein  wertvolles Ausgangsmaterial zur Herstellung  von Farbstoffen dar.  



  <I>Beispiel:</I>  Eine fein verteilte     Aufschlemmung    von  18,5 Teilen     Cyanurchlorid    in 1000 Teilen  Wasser wird mit Salzsäure schwach sauer  gestellt und nach und nach bei 0   unter Rüh-         ren    mit einer Lösung von 26.2 \feilen 2     #        8-          amiuonaphthol-6-sulfosaureixi    Natrium in 500  Teilen Wasser versetzt, wobei man durch  Zugabe von     Sodalösung    (im ganzen 5,3 Teile)  die Reaktion immer schwach sauer hält.

   Die  so erhaltene klare Lösung wird in der Kälte  mit Soda neutralisiert und wiederum mit  einer weiteren Lösung von 26.2 Teilen des       Natronsalzes    der 2   8 -     Aminonaphthol    - 6     -          sulfosäure    versetzt. Man rührt, bis die       Aminonaphtholsulfosäure    beinahe verschwun  den ist, und isoliert das sekundäre Konden  sationsprodukt aus einem     Mol.        Cyanurchlorid     und zwei     Mol.    2 -     8-AminonaphtIloi-6-sulfo-          säure    durch Ansäuern,     Aussalzen    und Fil  trieren.



  Process for the production of a new intermediate product. It has been found that a new intermediate, the secondary condensation product of a blol. Cyanuric chloride with two 31o1. 2 - 8 - aminonaphthol - 6 - sulfonic acid, is obtained when two moles of 2 # 8 - aminonaphthol - 6 - sulfonic acid are allowed to act on one mole of cyanuric chloride.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found. that as such water is surprisingly very suitable. The secondary condensation product of one mole of cyanuric chloride with two moles of 2-8-aminonaphthol-6-sulfonic acid forms a crystalline, almost colorless powder that is readily soluble in water. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



  <I> Example: </I> A finely divided slurry of 18.5 parts of cyanuric chloride in 1000 parts of water is made weakly acidic with hydrochloric acid and gradually at 0 with stirring with a solution of 26.2 \ files 2 # 8- amiuonaphthol-6-sulfosaureixi sodium is added in 500 parts of water, and the reaction is always kept slightly acidic by adding soda solution (5.3 parts in total).

   The clear solution thus obtained is neutralized in the cold with soda, and a further solution of 26.2 parts of the sodium salt of 28-aminonaphthol-6-sulfonic acid is added. The mixture is stirred until the aminonaphtholsulphonic acid has almost disappeared and the secondary condensation product is isolated from one mole of cyanuric chloride and two moles of 2-8-aminonaphthol-6-sulfonic acid by acidification, salting out and filtration.
