  Verfahren zur Herstellung eines neuen     Zwisehenproduktes.       Es wurde gefunden,     da.ss    man ein neues  Zwischenprodukt, das tertiäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        1.8-Aminonaphthol-3.6-disulfo-          säure    und zwei     Mol.    Anilin, erhält,

   wenn man  auf ein     Mol.        Cyanurchlorid    in beliebiger Rei  henfolge ein     Mol.        1.8-Aminonaphthol-3.6-          disulfosäure    und zwei     Mol.    Anilin 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 ista  Das tertiäre Kondensationsprodukt aus einem       Mol.        Cya,nurchlorid    mit einem     Mol.        1.8-          Aminonaphthol-3.6-disulfosäure    und zwei       Mol.    Anilin bildet als     Alkalisalz    ein in Was  ser lösliches, fast     farbloses    Pulver. Es, ent  hält kein reaktionsfähiges Chloratom mehr  und stellt ein wertvolles Ausgangsmaterial  zur Herstellung von Farbstoffen dar.  



       Beispiel:     In eine     Aufschlemmung    von 18,5 Teilen       Cya.nurchlorid    in 500 Teilen Wasser lässt .man    eine Lösung von 34,3 Teilen des     Dinatrium-          salzes    der     1.8-Aminonaphthol-3.6-disulfo-          säure    in 150 Teilen .Wasser fliessen. Sobald  alles     Cyanurchlorid    verschwunden ist, wird  mit 30 Teilen kristallisiertem     Natriuma:cetat     und 12,9 Teilen     Anilinchlorhydrat    versetzt       und    weiter .gerührt,     bis    das Anilin fast voll  ständig verschwunden ist.

   Ist dies erreicht,  so wird     abermals    mit 30 Teilen kristallisier  tem     Natriumacetat    und 12,9 Teilen Anilin  chlorhydrat versetzt. Hierauf wird am Rück  flusskühler     ,gekocht,    und wenn das Anilin     wie-          derum    fast verschwunden ist, wird das ter  tiäre     Kondensationsprodukt    aus einem     Mol.     1 .     8-Aminonaphthol-3    .     6-disusfosäure    und  zwei     Mol.    Anilin durch     Aussalzen    abgeschie  den,     filtriert    und getrocknet.



  Process for the manufacture 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 1,8-aminonaphthol-3,6-disulfonic acid and two moles of aniline, is obtained,

   if one mole of 1.8-aminonaphthol-3.6-disulfonic acid and two moles of aniline 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. The tertiary condensation product of one mole of cyano chloride with one mole of 1.8-aminonaphthol-3.6-disulfonic acid and two moles of aniline, as the alkali metal salt, forms an almost colorless powder which is surprisingly very suitable. It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



       Example: A solution of 34.3 parts of the disodium salt of 1.8-aminonaphthol-3.6-disulphonic acid in 150 parts of water is allowed to flow into a suspension of 18.5 parts of cyano chloride in 500 parts of water. As soon as all of the cyanuric chloride has disappeared, 30 parts of crystallized sodium acetate and 12.9 parts of aniline chlorohydrate are added and the mixture is stirred until the aniline has almost completely disappeared.

   If this is achieved, 30 parts of crystallized sodium acetate and 12.9 parts of aniline chlorohydrate are added again. It is then boiled on the reflux condenser, and when the aniline has again almost disappeared, the tertiary condensation product is one mole. 8-aminonaphthol-3. 6-disusfoic acid and two moles of aniline separated by salting out, filtered and dried.
