Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das tertiäre Kondensations  produkt von einem Mol. Cyanurchlorid mit  einem Mol. 2.5-Aminonaphthol-7-sulfosäure  und zwei Mol. Anilin, erhält, wenn man  auf ein Mol. Cyanurchlorid in beliebiger  Reihenfolge ein Mol.     2.5-Aminonaphthol-7-          sulfosäure    und zwei Mol. Anilin einwirken  lässt.  



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in einem geeig  neten Verdünnungsmittel durchgeführt, und  es wurde gefunden, dass Wasser als solches  in überraschender Weise sehr gut geeignet  ist. Das tertiäre Kondensationsprodukt aus  einem Mol. Cyanurchlorid mit einem Mol.  2.5-Aminonaphthol-7-sulfosäure und zwei  Mol. Anilin bildet als Alkalisalz ein in Was  ser lösliches, fast farbloses Pulver. Es ent  hält kein reaktionsfähiges Chloratom mehr  und stellt ein wertvolles Ausgangsmaterial  zur Herstellung von Farbstoffen dar.  



  Beispiel:  Eine fein verteilte Ausschlemmung von  18,5 Teilen Cyanurchlorid in 1000 Teilen    Wasser wird nach und nach bei 0  unter Rüh  ren mit einer Lösung von 26,2 Teilen     2,5-          aminonaphthol-7-sulfosaurem    Natrium ver  setzt, wobei man durch Zugabe von Soda  lösung (im ganzen 5,3 Teile) die Reaktion  stets eben sauer hält. Die so erhaltene klare  Lösung wird nun mit 9,3 Teilen Anilin ver  setzt. Man rührt bei Zimmertemperatur, bis  das Anilin verschwunden ist, indem man  weiter die entstehende Salszäure mit Soda  neutralisiert.

   Zu der so erhaltenen Lösung  fügt man nun nochmals 9,3 Teile Anilin  und kocht zirka eine Stunde am     Rüekfluss-          kühler.    Hierauf wird durch Aussalzen und  Filtrieren das tertiäre Kondensationsprodukt  aus einem Mol. Cyanurchlorid, einem Mol.  2 . 5 - aminonaphtol-7-sulfosaurem Natrium  und zwei Mol. Anilin isoliert.



  Process for the production of a new intermediate product. It has been found that a new intermediate product, the tertiary condensation product of one mole of cyanuric chloride with one mole of 2,5-aminonaphthol-7-sulfonic acid and two moles of aniline, is obtained if one mole of cyanuric chloride is used in any order 2.5-aminonaphthol-7-sulfonic acid and two moles of aniline.



  This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that water as such is surprisingly very suitable. The tertiary condensation product of one mole of cyanuric chloride with one mole of 2,5-aminonaphthol-7-sulfonic acid and two moles of aniline, as an alkali salt, forms an almost colorless powder which is soluble in water. It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



  Example: A finely divided exclusion of 18.5 parts of cyanuric chloride in 1000 parts of water is gradually added to a solution of 26.2 parts of 2,5-aminonaphthol-7-sulfonic acid sodium at 0 while stirring Soda solution (5.3 parts in total) always keeps the reaction acidic. The clear solution thus obtained is now ver sets with 9.3 parts of aniline. The mixture is stirred at room temperature until the aniline has disappeared by further neutralizing the resulting hydrochloric acid with soda.

   A further 9.3 parts of aniline are then added to the solution thus obtained and the mixture is boiled on the reflux cooler for about an hour. Then the tertiary condensation product of one mole of cyanuric chloride, one mole of 2. 5 - aminonaphtol-7-sulfonic acid sodium and two moles. Aniline isolated.
