  Zusatzpatent zum Hauptpatent     Nr.    205164.    Verfahren     zür    Herstellung eines neuen Derivates eines     Azofarbstoffes.       Es wurde gefunden,     dass    man ein neues  Derivat eines     Azofarbstoffes    erhält, wenn man  <B>1</B>     Mol    des     Disazofarbstoffes,

      der erhalten wird  durch Vereinigen eines Moleküls der     1.3-Di-          aminobenzol-4-sulfonsäure    mit<B>1</B>     Mol    des       diazotierten        Monoazofarbstoffes    aus     diazotier-          ter        4-Amino-4-nitrodiphenylamiii-2'-sulfon-          säure    und     1-Amino-3-methylbenzol,    mit 2     Mol          Benzoylchlorid    in Gegenwart einer tertiären  Base     acyliert.     



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



  <I>Beispiel:</I>  <B>1</B> Teil des     Disazofarbstoffes,    der erhalten  wird durch Vereinigen der     1.3-Diaminoben-          zol-4-sulfonsäure    mit dem     diazotierten        Dis-          azofarbstoff    aus     diazotierter        4-Amino-4'-nitro-          diphenylamin-2'-sulfonsäure    und     1-Amino-3-          methylbenzol,    wird in 4 Teilen     Pyridin    sus  pendiert und bei 401 mit 1,25 Teilen Ben-         zoylchlorid    versetzt.

   Man erwärmt allmählich  auf<B>900</B> und hält diese Temperatur<B>1</B> 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 <B> 1 </B> mol of the disazo dye,

      which is obtained by combining a molecule of 1,3-di-aminobenzene-4-sulfonic acid with 1 mol of the diazotized monoazo dye from diazotized 4-amino-4-nitrodiphenylamiii-2'-sulfonic acid and 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.



  <I> Example: </I> <B> 1 </B> Part of the disazo dye which is obtained by combining the 1,3-diaminobenzene-4-sulfonic acid with the diazotized disazo dye from diazotized 4-amino-4 ' -nitro-diphenylamine-2'-sulfonic acid and 1-amino-3-methylbenzene, is suspended in 4 parts of pyridine and added at 401 with 1.25 parts of benzoyl chloride.

   The temperature is gradually increased to <B> 900 </B> and this temperature is maintained for <B> 1 </B> hour. After this time, the dibenzoyl product is deposited and dried.
