Description

  

      Verfahren    zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man     ein,    neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem     Mol.        Cyanurchlorid     mit zwei     Nol.    1     #        8-Aminonaphthol-3        #        6-di-          sulfosäure,    erhält,

   wenn _ man     .auf    ein     Mol.          Cyanurchlorid    zwei     Mol.    1     #        8-Aminonaphthol-          3.        6-disulfosäure    einwirken lässt.  



  Diese Kondensation wird durch Zusam  menrühren der Komponenten in einem geeig  neten     Verdünnungsmittel    durchgeführt, und  es wurde gefunden,     da.ss    als solches Wasser in       überraschender    Weise sehr gut .geeignet ist.  Das sekundäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid    mit zwei     Mol.    1.     8-          Aminonafphthol-3    .     6-disulfosäure    bildet ein in  Wasser     leicht    lösliches, kristallinisches, fast  farbloses Pulver.

   Es enthält noch ein reak  tionsfähiges Chloratom und stellt ein wert  volles Ausgangsmaterial zur Herstellung von  Farbstoffen dar.  



       Beispiel:     31,9 Teile     1.8-Aminonaphthol-3.6-di-          sulfosäure    werden in 500 Teilen Wasser unter  Zusatz von 13,3 Teilen 30     %iger        Natronlauge       gelöst, mit 18,5 Teilen     Cyanurchlorid    versetzt  und gerührt, bis die Komponenten verschwun  den sind. Die so erhaltene saure Lösung wird  sehr vorsichtig fast genau neutralisiert und  mit einer Lösung von 81,9 Teilen     1.8-          Alminonaphthol=3.        6-disulfosäure,    13,8 Teilen  30     %iger        Natronlauge    und<B>"30</B> Teilen Na  triumacetat in 150 Teilen Wasser versetzt.

    Nach einigem Rühren ist die     Aminonaphthol-          sulfosä,ure    beinahe verschwunden und das be  reits teilweise .ausgeschiedene sekundäre Kon  densationsprodukt aus einem-     Mol.        Cyanur-          chlorid    und zwei     Mol.    1     #        8-Aminonaphthol-          3.6-disulfosäure    wird durch     Kochsalzzusatz          vollständig    .gefällt und filtriert.



      Process for the production of a new intermediate product. It has been found that a, new intermediate, the secondary condensation product of one mole. Cyanuric chloride with two Nol. 1 # 8-aminonaphthol-3 # 6-disulfonic acid, receives,

   if two moles of 1 # 8-aminonaphthol-3. 6-disulfonic acid are allowed to act 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, surprisingly, water is very suitable as such. The secondary condensation product of one mole of cyanuric chloride with two moles of 1. 8-aminonafphthol-3. 6-disulfonic acid forms a crystalline, almost colorless powder that is easily soluble in water.

   It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



       Example: 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid are dissolved in 500 parts of water with the addition of 13.3 parts of 30% strength sodium hydroxide solution, mixed with 18.5 parts of cyanuric chloride and stirred until the components have disappeared. The acidic solution obtained in this way is very carefully neutralized almost exactly and with a solution of 81.9 parts of 1,8-alminonaphthol = 3 6-disulfonic acid, 13.8 parts of 30% strength sodium hydroxide solution and 30 parts of sodium acetate in 150 parts of water are added.

    After some stirring, the aminonaphthol sulfonic acid has almost disappeared and the secondary condensation product, which has already partially separated out, consisting of one mole of cyanuric chloride and two moles of 1 # 8-aminonaphthol-3,6-disulfonic acid, is completely precipitated and filtered.
