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.    Wasser und zwei     Mol.        2#        5-Amino-          naphthol-7-sulfosäure    erhält,

   wenn man auf  ein     Mol.        Cyanurchlorid    in beliebiger Reihen  folge ein     Mol.    Wasser und zwei     Mol.    2     #        5-          Aininonaphthol-7-sulfosäure    einwirken lässt.  



  Diese Kondensation wird durch Zusammen  rühren der Komponenten in einem geeigneten  Verdünnungsmittel durchgeführt, und es wurde  gefunden, dass Wasser als solches in über  raschender Weise sehr gut geeignet ist. Das  tertiäre Kondensationsprodukt aus einem     Mol.          Cyanur        chlorid    mit einem     Mol.    Wasser und  zwei     Mol.    2     #        5-Aminoiiaphthol-7-sulfosäurebil-          det    als     Alkälisalz    ein in Wasser lösliches,  fast farbloses Pulver.

   Es enthält kein reak  tionsfähiges Chloratom mehr und stellt ein  wertvolles Ausgangsmaterial zur Herstellung  von     Farbstoffen    dar.         Beispiel:       Eine fein verteilte     Aufschlemmung    von  18,5 Teilen     Cyanurohlorid    in 1000 Teilen    Wasser wird mit Salzsäure schwach sauer  gestellt und nach und nach. bei 0   unter  Rühren - 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.

   Die  so erhaltene klare Lösung wird in der Kälte  mit Soda neutralisiert und mit einer weiteren       Lösung    von 26,2 Teilen des     Natronsalzes    der  2     #        5-Aminonaphthol-7-sulfosäure    versetzt, wo  bei man durch Zugabe von     Sodalösung    die  Reaktion schwach sauer hält.

   Ist alle 2     #    5  Aminonaphthol-7-sulfosäure verschwunden, so  neutralisiert man vollständig, setzt 25 Teile  30      /oige    Natronlauge hinzu und kocht eine  Stunde am     Rückflusskühler.    Nach Neutrali  sation des überschüssigen Alkalis isoliert man  das tertiäre Kondensationsprodukt aus 1     Mol.          Cyanurchlorid,    ein     Mol.    Wasser und zwei     Mol.     2     #        5-Aminonaphthol-7-sulfosäure    durch Aus  salzen und Filtrieren.



  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 water and two moles of 2 # 5-amino-naphthol-7-sulfonic acid, is obtained,

   if one mole of cyanuric chloride is allowed to act in any order, one mole of water and two moles of 2 # 5-ainonaphthol-7-sulfonic acid.



  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 water and two moles of 2 # 5-aminoaphthol-7-sulfonic acid, as 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 slurry of 18.5 parts of cyanuric chloride in 1000 parts of water is made slightly acidic with hydrochloric acid and gradually made. at 0 with stirring - with a solution of 26.2 parts of 2 # 5-aminonaphthol-7-sulphonic acid sodium in 500 parts of water; whereby one keeps the reaction always weakly acidic by adding soda solution (total 5.3 parts).

   The clear solution obtained in this way is neutralized in the cold with soda and mixed with a further solution of 26.2 parts of the sodium salt of 2 # 5-aminonaphthol-7-sulfonic acid, where the reaction is kept slightly acidic by adding soda solution.

   When all 2 # 5 aminonaphthol-7-sulfonic acid has disappeared, it is completely neutralized, 25 parts of 30% sodium hydroxide solution are added and the mixture is boiled for one hour on the reflux condenser. After neutralizing the excess alkali, the tertiary condensation product is isolated from 1 mole of cyanuric chloride, one mole of water and two moles of 2 # 5-aminonaphthol-7-sulfonic acid by salting out and filtering.
