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. Benzidin und zwei Mol.     1.8-          Aminonaphthol-3.6-disulfosäure,    erhält, wenn  man auf ein Mol. Cyanurchlorid in beliebiger  Reihenfolge ein Mol. Benzidin und zwei Mol.  1 . 8-Aminonaphthol-3.6-disulfosäure einwir  ken lässt.  



  Diese Kondensatiou 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. Benzidin  und zwei Mol.     1.8-Aminonaphthol-3.6-di-          sulfosäure    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:  Zu einer Aufschlemmung von 18,5 Teilen  Cyanurchlorid in 1000 Teilen Wasser gibt    man eine Lösung von 33,1 Teilen des     Di-          natriumsalzes    der     1.8-Aminonaplhthol-3.6-          disulfosäure    und rührt, bis die Komponenten  verschwunden sind. Hierauf stellt man mit  Soda neutral, fügt     abermals    eine Lösung von  33,1 Teilen des Dinatriumsalzes der     1.8-          Aminonaphthol-3.6-disulfosäure    hinzu und  rührt weiter, bis zum fast vollständigen Ver  schwinden des Aminonaphthols. Man neu  tralisiert wiederum mit Soda, fügt 18,4 Teile  fein pulverisiertes Benzidin hinzu und kocht  längere Zeit unter Rühren.

   Die klare Lösung  wird hierauf ausgesäuert und das tertiäre  Kondensationsprodukt von einem Mol.     Cya-          nurchlorid    mit einem Mol. Benzidin und zwei  Mol. 2 . 8-Aminonaphthol-3 . 6-disulfosäure  filtriert und     getrocknet.  



  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 benzidine and two moles of 1,8-aminonaphthol-3,6-disulfonic acid, is obtained if one mole of cyanuric chloride is used in any order Benzidine and two moles. 8-aminonaphthol-3,6-disulfonic acid can act.



  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 benzidine and two moles of 1,8-aminonaphthol-3,6-disulfonic acid forms, as an alkali salt, 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 solution of 33.1 parts of the disodium salt of 1,8-aminonaphthol-3,6-disulfonic acid is added to a suspension of 18.5 parts of cyanuric chloride in 1000 parts of water and the mixture is stirred until the components have disappeared. Then it is made neutral with soda, a solution of 33.1 parts of the disodium salt of 1,8-aminonaphthol-3,6-disulfonic acid is again added and stirring is continued until the aminonaphthol has almost completely disappeared. You neutralize again with soda, add 18.4 parts of finely powdered benzidine and boil for a long time with stirring.

   The clear solution is then acidified and the tertiary condensation product of one mole of cyanuric chloride with one mole of benzidine and two moles of 2. 8-aminonaphthol-3. 6-disulfonic acid filtered and dried.
