Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das primäre Kondensations  produkt von einem Mol. Cyanurchlorid mit  einem Mol. 2.8-Aminonaphthol-6-sulfosäure  erhält, wenn man auf ein Mol. Cyanurchlorid  ein Mol. 2 . 8-Aminonaphthol-6-sülfosäure ein  wirken 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 primäre Kondensationsprodukt aus einem  Mol. Cyanurchlorid mit einem Mol.     2.8-          Aminonaphthol-6-sulfosäure    bildet ein in  Wasser leicht lösliches, kristallinisches, fast  farbloses Pulver. Es enthält noch zwei reak  tionsfähige Chloratome und stellt ein wert  volles Ausgangsmaterial zur Herstellung von  Farbstoffen dar.  



  Beispiel:  Eine fein verteilte Aufschlemmung von  18,5 Teilen Cyanurehlorid 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 Teilen 2.     8-          aminonaphthol-6-sulfosaurem    Natrium in 500    Teilen Wasser versetzt, wobei man durch Zu  g a be von Sodalösung (im ganzen 5,3 Teile)  die Reaktion immer schwach sauer hält. Die  so erhaltene klare Lösung enthält das     Kon-          densationsprodukt    von einem Mol.     Cyanur-          ehlorid    mit einem Mol. 2 .     8-Aminonaphthol-          6-sulfosäure,    das durch Kochsalz und Säure  zusatz gefällt wird.



  Process for the production of a new intermediate product. It has been found that a new intermediate product, the primary condensation product of one mole of cyanuric chloride with one mole of 2,8-aminonaphthol-6-sulfonic acid, is obtained if one mole of second cyanuric chloride is used for one mole of cyanuric chloride. 8-aminonaphthol-6-sulphonic acid can 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 primary condensation product of one mole of cyanuric chloride with one mole of 2,8-aminonaphthol-6-sulfonic acid forms a crystalline, almost colorless powder which is easily soluble in water. It still contains two reactive chlorine atoms and is a valuable starting material for the production of dyes.



  Example: 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 ren with a solution of 26.2 parts of 2. 8-aminonaphthol-6-sulfonic acid in sodium at 0 with stirring 500 parts of water are added, and the reaction is always kept slightly acidic by adding soda solution (5.3 parts in total). The clear solution thus obtained contains the condensation product of one mole of cyanuric chloride with one mole of 2. 8-aminonaphthol-6-sulfonic acid, which is precipitated by adding table salt and acid.
