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-4,6-          disulfosäure    und 1     Mol        Dehydrothiotoluidin-          sulfosäure    aufeinander einwirken lässt.  



  Das sekundäre     Kondensationsprodukt    aus  1     Mol        Cyanurchlorid,    1     Mol        1,8-Aminonaph-          thol-4,6-disulfosäure    und 1     Mol        Dehydrothioto-          luidinsulfosäure    bildet ein gelbes Pulver, das  sich in     Sodalösung    fast farblos löst. Es be  sitzt ausgesprochene Affinität zur     Baumwoll-          faser    und kann auf dieser, zum Beispiel  durch Behandeln mit     Diazoverbindungen,    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-4,6-disulfosäitre    ver  einigt und damit während     1-11z    Stunden  bei 0  gerührt. Während dieser Zeit lässt man  langsam eine Lösung von 5,3 Gewichtsteilen    Soda zufliessen. Hierauf fügt man eine neu  trale Lösung von 32     Gewichsteilen        Dehydro-          thiotoluidinsulfosäure    zu, steigert die Tempe  ratur auf 40   und lässt während     11z    Stunden  wieder eine Lösung von 5,3 Gewichtsteilen  Soda zufliessen.

   Aus der schwach gelb ge  färbten Lösung kann nach weiterem ein  stündigem Rühren das sekundäre Konden  sationsprodukt aus 1     Mol        Cyanurchlorid,    1       Mol        1,8-Aminonaphthol-4,6-disulfosäure    und  1     Mol        Dehydrothiotoluidinsulfosäure    durch  Zufügen von Kochsalz abgeschieden werden.  



  Zum gleichen Produkt gelangt man, wenn  man auf das     Cyanurchlorid    zunächst die       Dehydrothiotoluidinsulfosäure    und dann das       Aminonaphthol    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-4,6-disulfonic acid and 1 mole of dehydrothiotoluidine sulfonic acid are allowed to act on one another.



  The secondary condensation product of 1 mole of cyanuric chloride, 1 mole of 1,8-aminonaphthol-4,6-disulfonic acid 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.



  <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-4,6-disulfonic acid, and thus for 1-11z Stirred at 0 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 a period of 11z hours.

   After a further hour of stirring, the secondary condensation product of 1 mole of cyanuric chloride, 1 mole of 1,8-aminonaphthol-4,6-disulfonic acid and 1 mole of dehydrothiotoluidinsulfonic acid can be deposited by adding sodium chloride from the pale yellow colored solution.



  The same product is obtained if the dehydrothiotoluidinsulfonic acid and then the aminonaphthol are allowed to act on the cyanuric chloride.
