Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes.       Es wurde gefunden, dass man ein     neues     Zwischenprodukt, das tertiäre Kondensations  produkt von einem     Mol.        Cyanurohlorid    mit  einem     h1.ol.        2.8-Aminonaphthol-6-sulfosäure     und zwei     Mol.    Phenol, erhält,

   wenn man auf  ein     Mol.        Cyanurchlorid    in beliebiger Reihen  folge ein     Mol.        2.8-Aminonaphthol-6-sulfo-          säure        und    zwei     Mol.    Phenol einwirken     lässt.     



  Diese 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.        Cyanurchlorid    mit einem     Mol.     2 .     8-Aminonaphthol-6-sulfosä        ure    und zwei       Mol.    Phenol bildet als     Alkalisalz    ein in Was  ser lösliches, fast farbloses Pulver. Es ent  hält kein     rekationsfähiges    Chloratom mehr  und stellt ein wertvolles Ausgangsmaterial  zur Herstellung von Farbstoffen dar.

      <I>Beispiel:</I>  In eine     Suspension    von 18,5 Teilen     Cya-          nurchlorid    in der 20fachen Menge Wasser    werden bei 0  23,2 Teile     Phenolnatrium,    in  200 Teilen Wasser gelöst, derart eingetra  gen, dass die Reaktionsmasse immer schwach  alkalisch reagiert. Sobald in einer filtrierten  Probe sozusagen kein     Phenolnatrium    mehr  nachzuweisen ist, wird mit einer Lösung von  26,2 Teilen 2 .     8-aminonaphthol-6-sulfosaurem     Natrium versetzt und so lange gekocht, bis  die     Aminonaphtholsulfosäure    verschwunden  ist, indem- man durch stetes Neutralisieren  dafür sorgt, dass die entstehende Salzsäure  sofort abgestumpft wird.

   Die erkaltete Lö  sung wird angesäuert und das ausgefallene  tertiäre Kondensationsprodukt von einem       Mol.        2.8-Aminonaphthol-6-sulfosäure    und  zwei     Mol.    Phenol 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. Cyanuric chloride with an h1.ol. 2.8-aminonaphthol-6-sulfonic acid and two moles of phenol,

   if one mole of 2,8-aminonaphthol-6-sulfonic acid and two moles of phenol are allowed to act on one mole of cyanuric chloride in any order.



  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 2. 8-aminonaphthol-6-sulfonic acid and two moles. Phenol, as an alkali salt, forms an almost colorless powder that is soluble in water. It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

      <I> Example: </I> In a suspension of 18.5 parts of cyanuric chloride in 20 times the amount of water, 23.2 parts of sodium phenol are dissolved in 200 parts of water in such a way that the reaction mass is always slightly alkaline responds. As soon as no more sodium phenol can be detected in a filtered sample, a solution of 26.2 parts 2. Sodium 8-aminonaphthol-6-sulphonic acid is added and the mixture is boiled until the aminonaphthol-sulphonic acid has disappeared, by constantly neutralizing it to ensure that the hydrochloric acid formed is immediately blunted.

   The cooled solution is acidified and the precipitated tertiary condensation product of one mole of 2,8-aminonaphthol-6-sulfonic acid and two moles of phenol is filtered and dried.
