Description

  

      Terfahren    zur Herstellung eines neuen Zwischenproduktes.    Es     wurde    gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem     Mol.        Cyanurchlorid     mit einem     Mol.        2.5-AminGnaphthol-7-sulfo-          säure    und einem     Mol.        1-Amino-3-formyl-          aminobenzol,    erhält,

   wenn man auf ein     Mol.          Cyanurchlorid    in beliebiger Reihenfolge ein       Mol.        2.5-Aminonaphthol-7-sulfosäure    und  ein     Mol.        1-.Jlmino-3-formylaminobenzol    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     sekundäre    Kondensationsprodukt  aus     einem        -Mol.        Cyanurchlorid,    einem     Mol          2.5-Aminonaphthol-7-sulfosäure    und einem       Mol.        1-Amino-3-formylaminobenzol    bildet  ein in Wasser leicht lösliches, farbloses, kri  stallinisches Pulver.

   Es     enthält    noch ein     reak-          tionsfähiges    Chloratom und stellt ein wert  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   unter Rüh  ren mit einer Lösung von 26,2 Teilen 2 . 5  aminonaphthol-7-suifosauremNatrium in 500  Teilen Wasser versetzt, wobei man durch Zu  gabe von Sololösung (im ganzen 5,3 Teile)  die Reaktion immer schwach sauer hält.

   Zu  der so erhaltenen klaren Lösung, die mit  Soda genau neutralisiert worden ist, fügt  man nun<B>13,7</B> Teile     1-Amino-3-formylamino-          benzol    und rührt weiter, bis dieses ver  schwunden ist. Das gebildete Kondensations  produkt aus einem     Mol.        Cyanurchlorid,     einem     Mol.        2.5-Aminonaphthol-7-sulfosäure     und einem     Mol.        1-Amino-3-formylaminoben-          zol    wird hierauf, nach abermaligem Neutrali  sieren dar Reaktionsflüssigkeit mit Soda  lösung, durch     Aussalzen    isoliert.



      Proceeding to manufacture a new intermediate product. It has been found that a new intermediate, the secondary condensation product of one mole of cyanuric chloride with one mole of 2,5-amine-7-naphthol-7-sulfonic acid and one mole of 1-amino-3-formylaminobenzene, is obtained,

   if one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of 1-imino-3-formylaminobenzene are allowed to act on one mole of cyanuric chloride in any order.



  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 one mol. Cyanuric chloride, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole. 1-Amino-3-formylaminobenzene forms a colorless, crystalline powder which is readily soluble in water.

   It still contains a reactive chlorine atom 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 slightly acidic with hydrochloric acid and gradually at 0 while stirring ren with a solution of 26.2 parts 2. 5 aminonaphthol-7-suifosauremNatrium in 500 parts of water are added, whereby the reaction is always kept weakly acidic by adding solo solution (5.3 parts in total).

   13.7 parts of 1-amino-3-formylamino-benzene are now added to the clear solution thus obtained, which has been precisely neutralized with soda, and the mixture is stirred until it has disappeared. The condensation product formed from one mole of cyanuric chloride, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of 1-amino-3-formylaminobenzene is then isolated by salting out after the reaction liquid has been neutralized again with soda solution.
