Description

  

  Verfahren 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-Aminonaphthol-7-sulfo-          säure    und einem Mol. Anilin, erhält, wenn  man auf ein Mol. Cyanurchlorid in beliebiger  Reihenfolge ein Mol.     2.5-Aminonaphthol-7-          sulfosäure    und ein Mol. Anilin 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, einem Mol.  2.5-Aminonaphthol-7-sulfosäure und einem  Mol. Anilin bildet ein in Wasser leicht lös  liches, farbloses, kristallinisches Pulver. Es  enthält noch ein     reaktionsfälliges    Chloratom  und stellt ein wertvolles 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 natch bei 0  unter Rüh  ren mit einer Lösung von 26,2 Teilen     2.5-          aminonaphthol-7-sulfosaurem    Natrium in 500  Teilen Wasser versetzt, wobei man durch  Zugabe von Sodalösung (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 9,3 Teile Anilin und rührt weiter,  bis dieses verschwunden ist.

   Das gebildete  Kondensationsprodukt aus einem Mol.     Cya-          nurchlorid.    einem Mol.     2.5-Aminonaphthol-          7-sulfosäure    und einem Mol. Anilin wird  hi@rauf, nach abermaligem Neutralisieren  der Reaktionsflüssigkeit mit     Sodalösung,     durch     Aussalzen    isoliert.



  Process for the production of a new intermediate product. It has been found that a new intermediate product, the secondary condensation product of one mole of cyanuric chloride with one mole of 2.5-aminonaphthol-7-sulfonic acid and one mole of aniline, is obtained if one mole of cyanuric chloride in in any order, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of aniline 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 secondary condensation product of one mole of cyanuric chloride, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of aniline forms a colorless, crystalline powder which is easily 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 with stirring with a solution of 26.2 parts of 2.5-aminonaphthol-7-sulfonic acid sodium in 500 parts Water is added, and the reaction is always kept slightly acidic by adding soda solution (5.3 parts in total). 9.3 parts of aniline are now added to the clear solution thus obtained, which has been precisely neutralized with soda, and stirring is continued until this 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 aniline is isolated by salting out after the reaction liquid has been neutralized again with soda solution.
