  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 205164,    Verfahren zur Herstellung eines neuen Derivates eines     Azofarbstoffes.       Es wurde gefunden, dass man ein neues  Derivat eines     Azofarbstoffea    erhält, wenn man  1     Mol    des     Trisazofarbstoffes,    der erhalten wird  durch Vereinigen eines Moleküls der     1.3-Di-          aminobenzol-4-sulfonsäure    mit 1     Mol    des  dianotierten     Disazofarbstoffes    aus dianotierter       1-Aminonaphthalin-4.7-disulfonsäure    und     1-          Amino-3-methylbenzol,

          Weiterdiazotieren    und  Vereinigen mit einem zweiten Molekül     1-          Amino-3-methylbenzol,    mit 2     Mol        Benzoyl-          chlorid    in Gegenwart einer tertiären Base       acyliert.     



  Der neue     Farbstoff    stellt ein rotbraunes  Pulver dar und färbt Baumwolle in echten       orangebraunen    Tönen.  



       Beispiel:     1 Teil des     Trisazofarbstoffes,    der erhalten  wird durch Vereinigen der     1.3-Diaminobenzol-          4-sulfonsäure    mit dem dianotierten     Disazo-          farbstoff    aus dianotierter     1-Aminonaphthalin-          4.7-disulfonsäure    und     1-Amino-3-methylben-          zol,        Weiterdiazotieren    und Vereinigen mit       1-Amino-3-methylbenzol,    wird in 10 Teilen         Pyridin    suspendiert und bei 40   mit 1,

  2 Teilen       Benzoylchlorid    versetzt. Man erwärmt all  mählich auf<B>900</B> und hält diese Temperatur  1 Stunde. Nach dieser Zeit wird das     Diben-          zoylprodukt    abgeschieden und getrocknet.



  <B> Additional patent </B> 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 mole of the trisazo dye, which is obtained by combining one molecule of 1,3-di-aminobenzene-4-sulfonic acid with 1 mole of the dianotated disazo dye from dianotated 1-aminonaphthalene-4.7 -disulfonic acid and 1- amino-3-methylbenzene,

          Further diazotization and combining with a second molecule of 1-amino-3-methylbenzene, acylated with 2 moles of benzoyl chloride in the presence of a tertiary base.



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



       Example: 1 part of the trisazo dye which is obtained by combining the 1,3-diaminobenzene-4-sulfonic acid with the dianotized disazo dye from dianotated 1-aminonaphthalene-4,7-disulfonic acid and 1-amino-3-methylbenzene, further diazotizing and combining with 1-Amino-3-methylbenzene, is suspended in 10 parts of pyridine and at 40 with 1,

  2 parts of benzoyl chloride were added. It is gradually heated to <B> 900 </B> and held at this temperature for 1 hour. After this time, the dibenzoyl product is deposited and dried.
