Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden, dass man ein neues  Zwischenprodukt erhält, wenn man 1     Mol          Cyanurchlorid,    1     Mol        1,8-Aminonaphthol-3,6-          disulfosäure,    1     Mol    Anilin und 1     Mol        De-          hydrothiotoluidinsulfosäure    aufeinander ein  wirken lässt.  



  Das     ternäre    Kondensationsprodukt aus  1     Mol        Cyanurchlorid,    1     Mol        1,8-Aminonaph-          thol-3,6-disulfosäure,    1     Mol    Anilin und 1     Mol          Dehydrothiotoluidinsulfsoäure    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.

    <I>Beispiel:</I>  Eine feine Suspension von 18,5 Gewichts  teilen     Cyanurchlorid    in Eiswasser wird mit  einer neutralen Lösung von 31,9 Gewichts  teilen     1,8-Aminonaphthol-3,6-disulfosäure    ver  einigt und damit während     1-11/2    Stunden  bei 0<B>0</B> gerührt. Während dieser Zeit lässt man    langsam eine Lösung von 5,3 Gewichtsteilen  Soda zufliessen. Hierauf fügt man eine neu  trale Lösung von 32 Gewichtsteilen     Dehydro-          thiotoluidinsulfosäure    zu, steigert die Tempe  ratur auf 40   und lässt während 112 Stunden  wieder eine Lösung von 5,3 Gewichtsteilen  Soda zufliessen.  



  Man fügt nun 9,3 Gewichtsteile Anilin  zu und erwärmt     11/E    Stunden auf<B>80'.</B> Es  bildet sich das     ternäre    Kondensationsprodukt  aus 1     Mol        Cyanurchlorid,    1     Mol        1,8-Amino-          naphthol-3,6-disulfosäure,    1     Mol        Dehydro-          thiotoluidinsulfosäure    und 1     Mol    Anilin, das  durch     Aussalzen    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 1,8-aminonaphthol-3,6-disulfonic acid, 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 1,8-aminonaphthol-3,6-disulfonic acid, 1 mole of aniline and 1 mole of dehydrothiotoluidinsulfoic 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.

    <I> Example: </I> A fine suspension of 18.5 parts by weight of cyanuric chloride in ice water is combined with a neutral solution of 31.9 parts by weight of 1,8-aminonaphthol-3,6-disulfonic acid and is used for 1- Stirred for 11/2 hours at 0 <B> 0 </B>. 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 dehydrothiotoluidinsulphonic 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 112 hours.



  9.3 parts by weight of aniline are then added and the mixture is heated to 80 minutes for 11 / E hours. The ternary condensation product is formed from 1 mol of cyanuric chloride and 1 mol of 1,8-aminonaphthol-3,6 -disulfonic acid, 1 mol of dehydro thiotoluidinsulfonic acid and 1 mol of aniline, which can be precipitated and isolated by salting out.



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