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.    Anilin und zwei     Mol.    2 .     5-Amino-          na.phthol-7-sulfosäure,    erhält, wenn man auf  ein     Mol.        Cyanurchlorid    in beliebiger Reihen  folge ein     Mol.    Anilin und zwei     Mol.        2.5-          Aminonaphthol-7-sulfosäure        einvTirken    lässt.  



       Diesa    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.        Cvanurchlorid    mit einem     Mol.     Anilin und zwei     D,Iol.        \?    .     5-Aminonaphthol-          7-sulfosäure    bildet als     Alkalisalz    ein in  Wasser lösliches, fast farbloses Pulver.

   Es  enthält kein     reaktionsfähiges    Chloratom mehr  und stellt ein wertvolles Ausgangsmaterial  zur Herstellung     vo.n    Farbstoffen dar.  



       Beisel:     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-sulfosaurem Natrium in 500  Teilen Wasser versetzt, wobei man durch Zu  gabe von     Sodalösung    (im ganzen 5,3 Teile)  die Reaktion immer schwach sauer hält.

   Die  so erhaltene klare Lösung     wird    in der Kälte  mit Soda neutralisiert und mit einer wei  teren Lösung von 26,2 Teilen des Natron  salzes der     2.5-Aminonaphthol-7-sulfosäure     versetzt, wobei man durch Zugabe von Soda  lösung die     Reaktion    schwach sauer hält.

   Ist  alle     2.5-Aminonaphthol-7-sulfosäure        ver-          schwunden,    so neutralisiert man vollständig,  setzt 9,3 Teile Anilin hinzu und kocht eine  Stunde am     Rückflusskühler.    Nachdem man  die entstandene Salzsäure     abermals    neutrali  siert, isoliert man das tertiäre Kondensations  produkt aus einem     Mol.        Cyanurchlorid,    einem       Mol.    Anilin und zwei     Mol.    2 .     5-Aminonaph-          thol-7-sulfosäure    durch     Aussalzen    und Fil  trieren.



  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 aniline and two moles of 2. 5-Amino-naphthol-7-sulfonic acid is obtained when one mole of aniline and two moles of 2.5-aminonaphthol-7-sulfonic acid are allowed to act in any order on one mole of cyanuric chloride.



       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 vanuric chloride with one mole of aniline and two D, Iol. \? . As an alkali salt, 5-aminonaphthol-7-sulfonic acid 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.



       Beisel: 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 of water are added, the reaction always being kept slightly acidic by adding soda solution (5.3 parts in all).

   The clear solution thus obtained is neutralized in the cold with soda and treated with a white direct solution of 26.2 parts of the sodium salt of 2.5-aminonaphthol-7-sulfonic acid, the reaction being kept slightly acidic by adding soda solution.

   When all the 2,5-aminonaphthol-7-sulfonic acid has disappeared, it is completely neutralized, 9.3 parts of aniline are added and the mixture is refluxed for one hour. After the hydrochloric acid formed is neutralized again, the tertiary condensation product is isolated from one mole of cyanuric chloride, one mole of aniline and two moles of 2. 5-aminonaphthol-7-sulfonic acid by salting out and filtering.
