Description

  

      Zusatzpatent    zum Hauptpatent Nr. 205164.    Verfahren zur Herstellung eines neuen Derivates eines     Azofarbstoffes.       Es wurde gefunden, dass man ein neues  Derivat eines     Azofarbstoffes    erhält, wenn man  1     Mol    des     Trisazofarbstoffes,

      der erhalten wird  durch Vereinigen eines Moleküls     1-Chlor-2.4-          diaminobenzol    mit 1     Mol    des dianotierten       Disazofarbstoffes    aus dianotierter     2-Amino-          naphthalin-4.8-disulfonsäure    und     1-Amino-          naphthalin-7-sulfonsäure,        Weiterdiazotieren     und Vereinigen mit einem Molekül     1-Amino-          3-methylberizol,    mit 2     Mol        Benzoylchlorid    in  Gegenwart einer tertiären Base     acyliert.     



  Der neue Farbstoff stellt ein braunes  Pulver dar und färbt Baumwolle in echten  braunen Tönen.  



  <I>Beispiel:</I>  1     blol    des     Trisazofarbstoffes,    der erhalten  wird durch     Vereinigen    von     1-Chlor-2.4-          diaminobenzol    mit dem dianotierten     Disazo-          farbstoff    aus dianotierter     2-Aminonaphthalin-          4.8-disulfonsäure    und     1-Aminonaphthaliri-7-          sulfonsäure,        Weiterdiazotieren    und Vereinigen  mit 1     Mol        1-Amino-3-methylbenzol,

      wird in  der 10- bis     15fachen    Menge     Pyridin    gelöst  und bei 40<B>0</B> mit 2.5     Mol        Benzoylchlorid    ver-    setzt. Man erwärmt allmählich auf<B>90'</B> und  hält diese Temperatur 1 Stunde. Nach dieser  Zeit wird das     Dibenzoylprodukt    abgeschieden  und getrocknet.



      Additional patent to main patent no. 205164. Process for the production of a new derivative of an azo dye. It has been found that a new derivative of an azo dye is obtained if 1 mol of the trisazo dye

      which is obtained by combining a molecule of 1-chloro-2,4-diaminobenzene with 1 mol of the dianotated disazo dye from dianotated 2-amino-naphthalene-4,8-disulfonic acid and 1-amino-naphthalene-7-sulfonic acid, further diazotizing and combining with a molecule 1- Amino-3-methylberizole, acylated with 2 moles of benzoyl chloride in the presence of a tertiary base.



  The new dye is a brown powder and dyes cotton in real brown tones.



  <I> Example: </I> 1 blol of the trisazo dye obtained by combining 1-chloro-2,4-diaminobenzene with the dianotated disazo dye from dianotated 2-aminonaphthalene-4,8-disulphonic acid and 1-aminonaphthalen-7-sulphonic acid , Further diazotizing and combining with 1 mol of 1-amino-3-methylbenzene,

      is dissolved in 10 to 15 times the amount of pyridine and mixed with 2.5 mol of benzoyl chloride at 40 0. The mixture is gradually heated to <B> 90 '</B> and held at this temperature for 1 hour. After this time, the dibenzoyl product is deposited and dried.
