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.        2.5-Aminonaphthol-7-sulfosäure     erhält, wenn man auf ein     Mol.        Cy        anurchlorid     ein     Mol.        2.5-Aminonaphthol-7-sulfosäure          einwirken    lässt.  



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in einem     .ge-eig-          neten    Verdünnungsmittel durchgeführt, und  es wurde gefunden,     d.ass    als solches Wasser  in überraschender Weise sehr gut     geeignet     ist.

   Das primäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid    mit einem     Mol.     2 .     5-Aminonaphthol-7-sulf        osäure    bildet ein in  Wasser leicht lösliches, kristallinisches, st  farbloses Pulver.     Es    enthält noch zwei     r.eak-          tionsfähige    Chloratome und stellt ein     we     volles Ausgangsmaterial zur Herstellung von  Farbstoffen dar.  



       Beispiel:          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<B>'</B>unter Rüh  ren mit     einer    Lösung von 26,2 Teilen 2. 5  a.minonaphthol-7-sulfosaurem Natrium in 500         Teilen    Wasser versetzt, wobei man durch Zu  gabe von     S.odalösung    (im ganzen 5,3 Teile)  die Reaktion     immer    schwach sauer hält.

   Die  so erhaltene klare Lösung enthält das     Kon-          densationspro,dukt    von einem     Mol.        Cyanur-          chlorid    mit ,einem     Mol.    2 .     5-Aminon.aphthol-          7-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 2.5-aminonaphthol-7-sulfonic acid, is obtained when one mole of 2.5-aminonaphthol-7-sulfonic acid is used for one mole of cyano chloride 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. 5-Aminonaphthol-7-sulfonic acid forms a crystalline, colorless powder which is easily soluble in water. It still contains two reactive chlorine atoms and is a wholesome 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 at 0 <B> '</B> with stirring with a solution of 26.2 parts 2. 5 a.minonaphthol-7-sulphonic acid sodium is added in 500 parts of water, and the reaction is always kept slightly acidic by adding sodium carbonate solution (5.3 parts in all).

   The clear solution thus obtained contains the condensation product of one mole of cyanuric chloride with one mole of 2. 5-aminonaphthol- 7-sulfonic acid, which is precipitated by adding table salt and acid.
