Description

  

      Verfahren    zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden,     da.ss    man ein neues  Zwischenprodukt erhält,     wenn    man 1     Mol.          Cyanurchlorid,    1     Mol.        1,8-Aminonaphthol-          3,6--disulfosäure    und 1     Mol.        Dehydrothioto-          luidinsulfosäure    aufeinander einwirken lässt.  



  Das sekundäre     Kondensationsprodukt    aus  1 Hol.     Cyanurchlorid,    1     Mol.        1,8-Amino-          naphthol-3,6-disulfosäureund    1     Mol.        Dehy-          drothiotoluidinsulfosä.ure    bildet ein gelbe  Pulver, .das sich in     Sodalösung    fast farblos  löst. Es besitzt     ausgesprochene    Affinität zur       Baumwoll,f        aser    und kann auf dieses Material  durch Behandeln mit     Diazoverbindungen    zu       Azofarbstoffen    entwickelt werden.

      <I>Beispiel:</I>    Eine feine Suspension von 18,5 Gewichts  teilen     Cyanurchlorid    in     Eiswasser    wird mit  einer neutralen Lösung von 31,9     Gewichts-          teilern    1,8 -     Aminonaphthol    - 3,6 -     disulfosäure     vereinigt und damit während 1 bis 11/2  Stunden bei 0   gerührt. Während dieser  Zeit lässt man langsam eine Lösung von 5,3    Gewichtsteilen Soda zufliessen. Hierauf fügt  man eine neutrale Lösung von 32 Gewichts  teilen     Dehydrothiotoluidinsulfosäure    zu, stei  gert die Temperatur auf 40   und lässt wäh  rend 11/2     ;Stunden    wieder eine Lösung von  5,3 Gewichtsteilen Soda zufliessen.

   Aus der  schwach gelb gefärbten Lösung kann nach  weiterem einstündigen Rühren das sekundäre  Kondensationsprodukt aus 1     Mol.        Cyanur-          chlori.d,    1     Mol.        1,8-Aminonaphthol-3,6-di-          sulfo.säure    und 1     Mol.        Dehydrothiotoluidin-          sulfosäure    durch Zufügen von Kochsalz ab  geschieden 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-3,6-disulfonic acid and 1 mole of dehydrothiotoluidinsulfonic acid are allowed to act on one another.



  The secondary condensation product from 1 hol. Cyanuric chloride, 1 mol. 1,8-amino-naphthol-3,6-disulphonic acid and 1 mol. Dehydrothiotoluidinsulphonic acid form a yellow powder which dissolves almost colorlessly in soda solution. It has a pronounced affinity for cotton, fiber and can be developed into azo dyes on this material by treating it 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 thus for 1 to Stirred at 0 for 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 raised to 40 and a solution of 5.3 parts by weight of soda is allowed to flow in again for 11/2 hours.

   After a further hour of stirring, the secondary condensation product of 1 mole of cyanuric chloride, 1 mole of 1,8-aminonaphthol-3,6-disulfonic acid and 1 mole of dehydrothiotoluidine sulfonic acid can pass through the slightly yellow solution Adding table salt to be divorced.



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