Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.         ä    s wurde gefunden,     dass    man ein neues       Zwischenprodukt,    das tertiäre Kondensations  produkt von einem     Mol.        Cyanurchlorid    mit  einem     Mol.        1,8-Aminonaphtol-3.,6-disulfosäure     und zwei Hol.

       o-Toluidin,    erhält, wenn man  auf ein     Mol.        Cyanurchlorid    in     beliebiger    Rei  henfolge     ein!        Mol.        1,8-Aminonaphtol-3,6--di-          sulfosäure    und zwei     Mol.        o-Toluidin    einwir  ken 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.        1,8-Ami-          nonaphtol-3,6-disulfosäure    und zwei     Mol.        o-          Toluidin    bildet als     Alkalisalz    ein in Wasser  lösliches, fast farbloses Pulver.

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



       Beispiel:     18,5 Teile     Cyanurchlorid    werden in 500       Teilen    Wasser suspendiert und mit -einer L6-         sung    von 83,1 Teilen des     Dinatriumsalzes    der  1,8 -     Aminonaphtol    - 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 kristallisiertes       Natriumacetat    hinzu und rührt bei gewöhn  licher Temperatur, bis kein     o-Toluidin    mehr  nachweisbar ist.

   Hierauf gibt man nochmals  10,7 Teile     o-Toluidin    und 14 Teile kristalli  siertes     Natriumaoetat    hinzu und erwärmt un  ter Rühren bis zum Verschwinden des     o-To-          luidins.    Das neue tertiäre     KondeDsationspro-          dukt    wird hierauf durch     Aussäuern    abge  schieden.



  Process for the production of a new intermediate product in the tar color industry. It was 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 hol.

       o-Toluidine, obtained if one moles of cyanuric chloride in any order! Mol. 1,8-aminonaphthol-3,6 - disulfonic acid and two mol. O-toluidine can 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 tertiary condensation product of one mole of cyanuric chloride with one mole of 1,8-aminonaphthol-3,6-disulfonic acid and two moles of o-toluidine forms, as the 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.



       Example: 18.5 parts of cyanuric chloride are suspended in 500 parts of water and stirred with a solution of 83.1 parts of the disodium salt of 1,8-aminonaphthol-3,6-disulfonic acid in 200 parts of water in the cold until clear Solution has occurred. 10.7 parts of o-toluidine and 28 parts of crystallized sodium acetate are now added and the mixture is stirred at the usual temperature until o-toluidine is no longer detectable.

   A further 10.7 parts of o-toluidine and 14 parts of crystallized sodium acetate are then added and the mixture is heated with stirring until the o-toluidine has disappeared. The new tertiary condensation product is then deposited by acidification.
