  Verfahren zur Herstellung eines neuen     Zwischenproduktes.       Es     wurde    gefunden, dass man ein neues  Zwischenprodukt, das tertiäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.    Anilin und zwei     Mol.        2.8-Amino-          naphthol-6-sulf        osäure,    erhält, wenn man auf  ein     Mol.        Cya.nurchlorid    in beliebiger Reihen  folge     ein        Mol.    Anilin und zwei     Mol.    2.

   8  Aminonaphthol-6-sulfosäure     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     tertiäre    Kondensationsprodukt .aus einem       Mol.        Cyanurchlorid    mit einem     Mol.    Anilin  und     zwei        Mol.        2.8-Aminonaphthol-6-sulfo-          säure        bildet    als     Alkalisalz    ein in Wasser lös  liches, fast farbloses Pulver.

   Es enthält kein       reaktionsfähiges    Chloratom mehr und stellt  ein wertvolles     Ausgangsmaterial    zur Herstel  lung von Farbstoffen dar.  



  <I>Beispiel:</I>  Eine fein     verteilte        Aufschlemmung    von  18,5 Teilen     Cyanurchlorid    in 1000 Teilen  Wasser wird     mit    Salzsäure rohwach sauer ge-    stellt und, nach und nach bei 0  unter Rühren  mit einer Lösung von 26,2 Teilen 2 .     8-amino-          naphthol-6-sulfosaurem    Natrium in 500 Tei  len Wasser versetzt, wobei     span        ,durch    Zugabe       vonSodalösung    (im     ganzen    5,3 Teile)     die    Re  aktion     immer    schwach sauer hält.

   Die so. er  h.altene klare Lösung wird in der Kälte mit  Soda neutralisiert     und    mit einer weiteren Lö  sung von 26,2 Teilen des     Natronsalzes    der       2.8-Aminonaphthol-6-sulfosäure    versetzt, wo  bei man durch Zugabe von     Sodalösung    die  Reaktion schwach sauer hält.

   Ist alle 2. 8  Amino-naphthol-6-sulfosäure verschwunden,  so     neutralisiert    man vollständig, setzt 9,3  Teile Anilin hinzu und kocht eine Stunde am       Rückflusskühler.    Nachdem man die entstan  dene Salzsäure     abermals        neutralisiert    hat,  isoliert man das tertiäre Kondensationspro  dukt aus einem     Mol.        Cyanurchlorid,    einem       Mol.        Anilin        und    zwei Mal. 2.

       8-Aminonaph-          thol-6-sulfosäure    durch     Aussalzen    und     Fil-          trieren.  



  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 aniline and two moles of 2,8-amino-naphthol-6-sulfonic acid, is obtained when one mole of cyanuric chloride is used in any order, one mole of aniline and two moles. 2.

   8 aminonaphthol-6-sulfonic acid.



  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 aniline and two moles of 2,8-aminonaphthol-6-sulfonic acid forms, as an alkali metal salt, 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.



  <I> Example: </I> A finely divided slurry of 18.5 parts of cyanuric chloride in 1000 parts of water is made acidic with raw wax and, gradually at 0 with stirring, with a solution of 26.2 parts of 2. Sodium 8-aminaphthol-6-sulphonic acid is added to 500 parts of water, with the addition of soda solution (5.3 parts in total) always keeping the reaction slightly acidic.

   The so. The clear solution that is kept is neutralized in the cold with soda and a further solution of 26.2 parts of the sodium salt of 2,8-aminonaphthol-6-sulfonic acid is added, the reaction being kept slightly acidic by adding soda solution.

   If all 2. 8 amino-naphthol-6-sulfonic acid has disappeared, the mixture is completely neutralized, 9.3 parts of aniline are added and the mixture is refluxed for one hour. After the hydrochloric acid formed has been neutralized again, the tertiary condensation product is isolated from one mole of cyanuric chloride, one mole of aniline and twice. 2.

       8-aminonaphthol-6-sulfonic acid by salting out and filtering.
