  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden,     da.ss    man ein neues  Zwischenprodukt, das tertiäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        2.5-Aminoilaphthol-7-sulfosäure     und zwei     Mol.        Monoformyl-1.3-phenylendi-          amin,    erhält,

   wenn man auf ein     Mol.        Cyanur-          chlo@rid    in beliebiger Reihenfolge ein     Mol.          2.5-Aminonaphth.ol-7-sulfosäure    und zwei       Mol.        Mo@noformyl-1.3-phenylendiamin    ein  wirken 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.     5-          Aminonaphthol-7-sulfosäure    und zwei     Mol.          l@Ionoformyl-1.3-phenylendiamin    bildet als       Alkalisa.lz    ein in Wasser lösliches, fast farb  loses Pulver.

   Es enthält kein reaktions  fähiges Chloratom mehr und stellt ein wert  volles Ausgangsmaterial zur Herstellung von  Farbstoffen dar.    <I>Beispiel:</I>  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    .     5-          aminonaphthol-7-sulfosaurem    Natrium ver  setzt, wobei man durch Zugabe von ' Soda  lösung (im ganzen 5,3 Teile) die Reaktion  stets eben sauer hält.

   Die so erhaltene klare  Lösung wird     nun    mit 13,6 Teilen     Mono-          formyl-1.3-phenylendi,amin    versetzt. Man  rührt bei Zimmertemperatur, bis das Mo     no-          fo@rmyl-1.3-phenylendiamin    verschwunden ist,  indem man weiter die entstehende Salzsäure  mit Soda. neutralisiert.

   Zu der so erhaltenen  Lösung fügt man nun nochmals 13,6 Teile       Monoformyl-1.3-phenylendi.amin    und kocht  zirka eine Stunde am     Rückflusskühler.    Hier  auf wird durch     Aussalzen    und     Fitrieren    das  tertiäre Kondensationsprodukt aus einem       Mol.        Cyanurohlorid,    einem     Mol.    2.     5-amino-          naphthol-7-sulfosaurem    Natrium und zwei       Mol.        Monoformyl-1.3-phenylendiamin        isoliert.  



  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 of cyanuric chloride with one mole of 2,5-aminoilaphthol-7-sulfonic acid and two moles of monoformyl-1,3-phenylenediamine, is obtained,

   if one mole of 2.5-aminonaphth.ol-7-sulfonic acid and two moles of monoformyl-1.3-phenylenediamine 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. 5- aminonaphthol-7-sulfonic acid and two moles of ionoformyl-1.3-phenylenediamine forms a water-soluble, almost colorless powder as alkali metal.

   It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes. <I> Example: </I> A finely divided slurry of 18.5 parts of cyanuric chloride in 1000 parts of water is gradually increased to 0 while stirring ren with a solution of 26.2 parts .2. 5- aminonaphthol-7-sulphonic acid sodium ver sets, whereby one keeps the reaction always acidic by adding 'soda solution (total of 5.3 parts).

   The clear solution thus obtained is then admixed with 13.6 parts of monoformyl-1,3-phenylenedi, amine. The mixture is stirred at room temperature until the monofo@rmyl-1.3-phenylenediamine has disappeared, by further treating the hydrochloric acid formed with soda. neutralized.

   A further 13.6 parts of monoformyl-1,3-phenylenediamine are then added to the solution thus obtained and the mixture is boiled on the reflux condenser for about an hour. Here, the tertiary condensation product is isolated from one mole of cyanuric chloride, one mole of 2.5-aminaphthol-7-sulfonic acid sodium and two moles of monoformyl-1,3-phenylenediamine by salting out and filtering.
