Description

  

  Verfahren zur. Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es     wurde    gefunden, dass man ein neues  Zwischenprodukt, das primäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        1,3-Phenylendiaminmonooxamin-          säure,    erhält, wenn man auf ein     Mol.        Cyanur-          chlorid    ein     Mol.        1,3-Phenylendiaminmono-          oxaminsäure        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 primäre Kondensationsprodukt aus  einem     Mol.        Cyanurchlorid    mit einem     Mol.          1,3-Phenylendi.aminmono@oxaminsäure    bildet  ein graues Pulver, das sich,- über<B>290'</B> erhitzt,  zersetzt. Es enthält noch zwei reaktionsfähige  Chloratome und stellt ein wertvolles Aus  gangsmaterial zur Herstellung von Farbstof  fen 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-phenylen-          diaminmono,oxaminsaures    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    filtriert  und der Filterrückstand getrocknet. Das Kon  densationsprodukt stellt ein graues Pulver  dar, das sich über<B>290'</B> C zersetzt.

   Es ent  hält noch zwei reaktionsfähige Chloratome.



  Procedure for. Manufacture of a new intermediate product for the tar color industry. It has been found that a new intermediate product, the primary condensation product of one mole of cyanuric chloride with one mole of 1,3-phenylenediamine monooxamic acid, is obtained if one mole of 1,3-phenylenediamine mono to one mole of cyanuric chloride - lets oxamic acid take effect.



  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 primary condensation product of one mole of cyanuric chloride with one mole of 1,3-phenylenediaminemono @ oxamic acid forms a gray powder which, when heated above 290 ', decomposes. It still contains two reactive chlorine atoms and is a valuable starting material for the production of dyes.



       Example: 20.2 parts of 1,3-phenylenediamine mono, oxamic acid sodium 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 to such an extent that the reaction mixture always remains lacemic. As soon as 3.6 parts of hydrochloric acid have become free, it is filtered and the filter residue is dried. The condensation product is a gray powder that decomposes over <B> 290 '</B> C.

   It still contains two reactive chlorine atoms.
