Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das tertiäre     KondensatHons-          produkt    von einem Mol. Cyanurchlorid mit  einem Mol. 2.8-Aminonaphthol-6-sulfosäure  und zwei Mol. 1.4-Phenylendiamin, erhält,  wenn man auf ein Mol. Cyanurchlorid in be  liebiger Reihenfolge ein Mol.     2.8-Amino-          naphthol-6-sulfosäure    und zwei Mol.     Mono-          acetyl-1.4-phenylendiamin    einwirken lässt  und das so erhaltene Produkt verseift.  



  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-sulfosäure und zwei  Mol. 1.4-Phenylendiamin bildet als Alkali  salz ein in Wasser lösliches, fast farblose@  Pulver. Es enthält kein reaktionsfähiges  Chloratom mehr und stellt ein wertvolles  Ausgangsmaterial zur Herstellung von Farb  stoffen dar.

      Beispiel:  Eine fein verteilte Aufschlemmung von  18,5 Teilen Cyanurchlorid in 1000 Teilen  Wasser wird nach und nach bei 0  unter Rüh  ren mit einer Lösung von 26,2 Teilen     2.8-          aminonaphthol-6-sulfosaurem    Natrium ver  setzt, wobei man durch Zugabe von     Sola-          lösung    (im ganzen 5,3 Teile) die Reaktion  stets eben sauer hält. Die so erhaltene klare  Lösung wird nun mit 15 Teilen     Monoacetyl-          1.4-phenylendiamin    versetzt. Man rührt bei  Zimmertemperatur, bis das     Monoacetyl-1.4-          phenylendiamin    verschwunden ist, indem man  weiter die entstehende Salzsäure mit Soda  neutralisiert.

   Zu der so erhaltenen Lösung  fügt man nun nochmals 15 Teile     Monoacetyl-          1.4-phenylendiamin    und kocht zirka eine  Stunde am Rückflusskühler. Hierauf wird  durch Aussalzen und Filtrieren das tertiäre  Kondensationsprodukt aus einem Mol.     Cya-          nurchlorid,    einem Mol.     2.8-Aminonaphthol-          6-sulfosäure    und zwei     Mol.        Monoa!cetyl-1.4-          phenylendiamin    isoliert.

   10 Teile des so er  haltenen Produktes werden so lange     mit    über  <I>s</I>     o        'hüssiger        verdünnter        Natronlauge   <B>-</B>     ek        olcht,         bis keine Zunahme der Diazotierbarkeit mehr       festzustellen    ist. Nach dem Erkalten wird  mit Mineralsäure angesäuert und das ausge  fallene tertiäre Kondensationsprodukt aus  einem Mol. 2.8-Amninonaphthol-6-sulfosäure  und zwei Mol. 1.4-Phenylendiamin durch  Filtrieren isoliert.



  Process for the production of a new intermediate product. It has been found that a new intermediate product, the tertiary condensate honing product of one mole of cyanuric chloride with one mole of 2,8-aminonaphthol-6-sulfonic acid and two moles of 1,4-phenylenediamine, is obtained if one mole of cyanuric chloride in be In any order, one mole of 2,8-amino-naphthol-6-sulfonic acid and two moles of monoacetyl-1,4-phenylenediamine are allowed to act and the product thus obtained is saponified.



  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 of 1,4-phenylenediamine, as an 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 gradually added at 0 while stirring with a solution of 26.2 parts of 2.8-aminonaphthol-6-sulfonic acid sodium, which is added by adding sol - solution (in total 5.3 parts) keeps the reaction acidic. The clear solution thus obtained is then mixed with 15 parts of monoacetyl-1,4-phenylenediamine. The mixture is stirred at room temperature until the monoacetyl-1,4-phenylenediamine has disappeared, by further neutralizing the hydrochloric acid formed with soda.

   A further 15 parts of monoacetyl-1,4-phenylenediamine are then added to the solution thus obtained and the mixture is boiled on the reflux condenser for about an hour. The tertiary condensation product is then isolated from one mole of cyanuric chloride, one mole of 2,8-aminonaphthol-6-sulfonic acid and two moles of monoacetyl-1,4-phenylenediamine by salting out and filtering.

   10 parts of the product obtained in this way are boiled with more than <I> s </I> o 'aqueous dilute caustic soda <B> - </B> until the diazotizability no longer increases. After cooling, it is acidified with mineral acid and the precipitated tertiary condensation product is isolated from one mole of 2,8-aminonaphthol-6-sulfonic acid and two moles of 1,4-phenylenediamine by filtration.
