Description

  

  Zusatzpatent zum Hauptpatent Nr. 135220.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es     wurde    gefunden, dass man einen neuen       Azofarbstoff    erhält,     wenn    man 1     Mol        Cyanur-          chlorid,1        Mo12,5-Amirronaphthol-7-sulfosäure,     1     Mol        p-Aminoacetanilid    und 1     Mol    der       Diazoverbindung    derjenigen     Dehydrothioto-          luidinsulfosäure,

      welche durch Backen des       Dehydrothiotoluidinsulfates    erhältlich ist,  derart aufeinander einwirken lässt, dass die       Amirronaphotholsulfosäur-e    und das     p-Amino-          acetanilid    durch den     Cyanurkern        -verbunden     werden und die     diazotierte        Dehydrothiotolui-          dinsulfosäure    in der     6-Stellung    des     Amino-          naphtholrestes    kuppelt.  



  Der neue     Farbstoff    bildet ein dunkles  Pulver. Er löst sich in Wasser mit roter  Farbe auf und erzeugt auf Baumwolle schar  lachrote Töne von grosser Reinheit und guter  Lichtechtheit.  



  <I>Beispiel:</I>  Zu einer neutralen Lösung von 50 Ge  wichtsteilen des sekundären Kondensations-         produktes    aus 1     Mol        Cyanurchlorid    1     Mol        2,5-          Aminonaphthol-7-sulfosärrre    und 1     Mol    Mono  acetyl-1,4-pherrylerrdiamin und 50 Teilen Na  triumacetat lässt man bei 45   die     Diazoverbin-          dungaus    32 Gewichtsteilen der     durchBacken    des       Dehydrothiotoluidirrsulfates    erhältlichen     Dehy-          drothiotoluidinmonosulfosäure    zufliessen.

   Nach  beendeter Kupplung wird der Farbstoff mit  Kochsalz ausgefällt und isoliert.



  Additional patent to main patent no. 135220. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if 1 mol of cyanuric chloride, 1 mol of 5-amirronaphthol-7-sulfonic acid, 1 mol of p-aminoacetanilide and 1 mol of the diazo compound of that dehydrothiotoluidinsulfonic acid

      which is obtainable by baking the dehydrothiotoluidine sulfate, can act on one another in such a way that the amirronaphotholsulfonic acid-e and the p-aminoacetanilide are connected by the cyanuric nucleus and the diazotized dehydrothiotoluidine sulfonic acid is coupled in the 6-position of the amino naphthol radical.



  The new dye forms a dark powder. It dissolves in water with a red color and produces sharp, laugh-red tones of great purity and good lightfastness on cotton.



  <I> Example: </I> For a neutral solution of 50 parts by weight of the secondary condensation product of 1 mole of cyanuric chloride, 1 mole of 2,5-aminonaphthol-7-sulfosärrre and 1 mole of monoacetyl-1,4-pherrylamine and 50 At 45 parts of sodium acetate, the diazo compound from 32 parts by weight of the dehydrothiotoluidine monosulfonic acid obtainable by baking the dehydrothiotoluidine sulfate is allowed to flow in.

   After the coupling has ended, the dye is precipitated with sodium chloride and isolated.
