Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes        der        Teerfarbenindustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem Hol.     Cyanurchlorid     mit zwei Hol.     1,3-Phenylendiaminmonooxa-          minsäure,    erhält, wenn man auf ein Hol.     Cya-          nurchlorid    zwei Hol.     1,3-Phenylendia.minmo-          nooxaminsäure    einwirken lässt.  



  Diese Kondensation wird durch     Zusa.m-          xnenrühren    der Komponenten in einem geeig  neten Verdünnungsmittel durchgeführt, und  es wurde gefunden,     dass    Wasser als solches  in überraschender Weise sehr gut geeignet  ist. Das sekundäre Kondensationsprodukt  aus einem Hol.     Cyanurchlorid    mit zwei Hol.       1.,3-Phenylendiaminmonooxaminsäure    bildet  ein graues Pulver, das über<B>300'</B> schmilzt.  ES enthält noch ein reaktionsfähiges Chlor  atom und stellt ein wertvolles Ausgangsma  terial zur Herstellung von Farbstoffen dar.

         Beispiel:     In eine Suspension von 18,5 Teilen     Cya-          nurchlorid    in der 20fachen Menge Wasser  werden in der Kälte 20,2 Teile     1,3-penyler=-          diatninmonooxaminsaures    Natrium in 200    Teilen Wasser langsam     zugerührt.    Gleich  zeitig wird die entstehende Salzsäure der  massen neutralisiert, dass die Reaktionsmasse  immer     lakmussauer    bleibt.

   Sobald 3,6 Teile  Salzsäure frei geworden sind, wird genau neu  tralisiert, bei gewöhnlicher Temperatur noch  mals 20,5 Teile     1,3-phenylendiaminmonooxa-          minsaures    Natrium zugegeben und     ea.    1  Stunde bei 40 bis<B>50'</B> gerührt. Es werden  unter Bildung des sekundären     Koudens.ations-          produktes    aus einem     Mol.        Cyanurchlorid    und  zwei     Mol.    1,3 -     Phenylen.dia,minmonooxamin-          säure    3,6 Teile Salzsäure frei. Das Konden  sationsprodukt wird durch Filtration isoliert.



  Process for the production of a new intermediate product in the tar color industry. It was found that a new intermediate product, the secondary condensation product of a Hol. Cyanuric chloride with two hol. 1,3-Phenylenediamine monooxamic acid, obtained when you get on a Hol. Cyanuric chloride two hol. 1,3-Phenylenedia.minmonoxamic 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 secondary condensation product from a haul. Cyanuric chloride with two hol. 1., 3-Phenylenediamine monooxamic acid forms a gray powder that melts over <B> 300 '</B>. ES still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.

         Example: 20.2 parts of 1,3-penylated sodium monooxamic acid in 200 parts of water are slowly stirred into a suspension of 18.5 parts of cyanuric chloride in 20 times the amount of water. At the same time, the resulting hydrochloric acid is neutralized in such a way that the reaction mixture always remains dry.

   As soon as 3.6 parts of hydrochloric acid have been released, the process is precisely neutralized, and a further 20.5 parts of 1,3-phenylenediamine monooxamic acid sodium are added at normal temperature and about 1 hour at 40 to 50 ' touched. 3.6 parts of hydrochloric acid are liberated, with the formation of the secondary koudensation product from one mole of cyanuric chloride and two moles of 1,3-phenylene-dia, minmonooxamic acid. The condensation product is isolated by filtration.
