Description

  

  Verfahren zur Herstellung eines neuen     Zwischenproduktes    der Teerfarbenindustrie.    Es wurde gefunden, dass man ein neues  Zwischenprodukt erhält, wenn man 1     Mol          Cyanurchlorid,    1     Mo12,5-Aminonaphthol-7-sul-          fosäure,    1     Mol    Anilin und 1     Mol        Dehydrothio-          toluidinsulfosäure    aufeinander einwirken lässt.  



  Das     ternäre    Kondensationsprodukt aus 1       Mol        Cyanurchlorid,    1     Mol        2,5-Aminonaphthol-          7-sulfosäure,    1     Mol    Anilin und 1     Mol        De-          hydrothiotoluidinsulfosäure    bildet ein gelbes  Pulver, das sich in     Sodalösung    fast farblos  löst. Es besitzt ausgesprochene Affinität zur  Baumwollfaser und kann auf dieser, zum  Beispiel durch Behandeln mit     Diazoverbin-          dungen,    in Farbstoffe übergeführt werden.  



       Beispiel:     Eine feine Suspension von 18,5 Gewichts  teilen     Cyanurchlorid    in Eiswasser wird mit  einer neutralen Lösung von 23,9 Gewichts  teilen     2,5-Aminonaphthol-7-sulfosäurevereinigt     und damit während     1-11/2    Stunden bei 0   gerührt. Während dieser Zeit lässt man lang  sam eine Lösung von 5,3 Gewichtsteilen Soda    zufliessen. Hierauf fügt man eine neutrale  Lösung von 32 Gewichtsteilen     Dehydrothio-          toluidinsulfosäure    zu, steigert die Temperatur  auf 40  und lässt während 11/2 Stunden wieder  eine Lösung von 5,3 Gewichtsteilen Soda  zufliessen.  



  Man fügt nun 9,3 Gewichtsteile Anilin zu  und erwärmt     112    Stunden auf 80 . Es bildet  sich das     ternäre    Kondensationsprodukt aus  1     Mol        Cyanurchlorid,    1     Mol        2,5-Aminonaph-          thol-7-sulfosäure,    1     Mol        Dehydrothiotoluidin-          sulfosäure    und 1     Mol    Anilin, das durch     Gus-          salzen    gefällt und isoliert werden kann.  



  Zum gleichen Produkt gelangt man, wenn  man die drei Komponenten in einer andern  Reihenfolge auf     Cyanurchlorid    einwirken lässt.



  Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate is obtained if 1 mole of cyanuric chloride, 1 mole of cyanuric chloride, 1 mole of aniline and 1 mole of dehydrothiotoluidinsulfonic acid are allowed to act on one another.



  The ternary condensation product of 1 mole of cyanuric chloride, 1 mole of 2,5-aminonaphthol-7-sulfonic acid, 1 mole of aniline and 1 mole of dehydrothiotoluidinsulfonic acid forms a yellow powder which dissolves almost colorlessly in soda solution. It has a pronounced affinity for cotton fibers and can be converted into dyes on this, for example by treatment with diazo compounds.



       Example: A fine suspension of 18.5 parts by weight of cyanuric chloride in ice water is combined with a neutral solution of 23.9 parts by weight of 2,5-aminonaphthol-7-sulfonic acid and stirred at 0 for 1-11 / 2 hours. During this time, a solution of 5.3 parts by weight of soda is allowed to flow in slowly. A neutral solution of 32 parts by weight of dehydrothiotoluidinsulfonic acid is then added, the temperature is increased to 40 and a solution of 5.3 parts by weight of soda is allowed to flow in again over 11/2 hours.



  9.3 parts by weight of aniline are then added and the mixture is heated to 80 for 112 hours. The ternary condensation product is formed from 1 mol of cyanuric chloride, 1 mol of 2,5-aminonaphthol-7-sulfonic acid, 1 mol of dehydrothiotoluidine sulfonic acid and 1 mol of aniline, which can be precipitated and isolated by means of cast salts.



  The same product is obtained if the three components are allowed to act on cyanuric chloride in a different order.
