Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes.    Es wurde gefunden, dass man ein neues  Zwischenprodukt, das sekundäre Kondensa  tionsprodukt von einem Hol.     Cyanurchlorid     mit einem Hol. 1     .8-Aminonaphthol-3.        6-di-          sulfosäure    und einem Hol.     o-Toluidin,    erhält,  wenn man .auf ein Hol.     Cyanurchlorid    in be  liebiger Reihenfolge ein Hol.     1.8-Amino-          naphtho1-3    .     6-clisulfosäure        und    ein Hol.     o-To-          luidin    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 sekundäre Kondensationsprodukt aus  einem Hol.     Cyanurchlorid    mit einem Hol.  1 .     8-Aminonaphtho1-3    .     6-.disulf        osäure        und     einem Hol.     o-Toluidin    bildet .als     Natriumsalz     ein in Wasser lösliches, fast farbloses Pulver.

    Es enthält noch ein     reaktionsfähiges    Chlor  atom und stellt ein     wertvolles        Ausgangsmate-          rial    zur Herstellung von Farbstoffen dar.  



       Beispiel:     18,5 Teile     Cyanurchlorid    werden in 500  Teilen Wasser suspendiert und mit einer Lö-         sung    von 83,1 Teilen des     Dinatriumsalzes    -der       1.8-Aminon,aphthol-3.6-disulfosäure    in 200  Teilen Wasser in der Kälte     verrührt,    bis  klare Lösung eingetreten ist.

   Man fügt nun  10,7 Teile     o-Toluidin    und 28 Teile kristalli  siertes     Natriumacetat    hinzu     und        rührt    bei  gewöhnlicher     Temperatur,    bis kein     o-Toluidin     mehr nachweisbar ist. - Das sekundäre Kon  densationsprodukt     ,aus    einem Hol.     Cyanur-          chlorid,    einem Hol. 1.     8-Aminon!aphthol-3    . 6  disnlfosäure und einem Hol.     o-Toluidin        wird     dann durch     Aussäurern    und     Aussalzen    iso  liert.



  Process for the production of a new intermediate product. It was found that a new intermediate product, the secondary condensation product of a Hol. Cyanuric chloride with a hol. 1,8-aminonaphthol-3. 6-disulfonic acid and a hol. o-toluidine, obtained if one .auf a hol. Cyanuric chloride in any order. 1,8-amino-naphtho1-3. 6-clisulfonic acid and a hol. lets o-toluidine 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 a hol. 1 . 8-aminonaphtho1-3. 6-.disulfonic acid and a hol. As a sodium salt, o-toluidine forms an almost colorless powder which is soluble in water.

    It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.



       Example: 18.5 parts of cyanuric chloride are suspended in 500 parts of water and stirred in the cold with a solution of 83.1 parts of the disodium salt of 1.8-aminone, aphthol-3.6-disulfonic acid in 200 parts of water until the solution is clear is.

   10.7 parts of o-toluidine and 28 parts of crystallized sodium acetate are then added and the mixture is stirred at ordinary temperature until o-toluidine is no longer detectable. - The secondary condensation product, from a hol. Cyanuric chloride, a hol. 1. 8-aminone! Aphthol-3. 6 disnlfoic acid and one hol. o-Toluidine is then isolated by acidification and salting out.
