  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  <B>1</B>     Mol    des     Trisazofarbstoffes,    der erhalten  wird durch Vereinigen eines Moleküls der       1,3-Diaminobenzol-4-sulfonsäure    mit<B>1</B>     Mol     des     diazotierten        Disazofarbstoffes    aus     diazo-          tierter        2-Amiiioiiaphtbalin-4,

  8-disulfonsäure     und<B>1</B>     Amino-S-methylberizol,        Weiterdiazo-          tieren    und Vereinigen mit einem zweiten  Molekül     1-Amiiio-S-methylbeiizol,    mit 2     Mol          Benzoylohlorid    in Gegenwart einer tertiären  Base     acyliert.     



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



  <I>Beispiel:</I>  <B>1</B>     Mol    des     Trisazofarbstoffes,    der erhalten  wird durch Vereinigen der     1,3-Diaminobenzol-          4-stilfotisäure    mit dem     diazotierten        Di8azo-          farbstoff    aus     diazotierter        2-Aminoinaphthalin-          4,8-disulfonsäure    und     1-Arnino-3-methylbenzol,          Weiterdiazotieren    und Vereinigen mit<B>1</B>     Mol          1-Amino-B-methylbenzol,

      wird in der<B>10-</B> bis  15fachen Menge des     Pyridins    gelöst und bei    400 mit 2     Mol        Benzoylchlorid    versetzt. Man  erwärmt allmählich auf<B>900</B> und hält diese  Temperatur eine Stunde. Nach dieser Zeit  wird das     Dibenzoylprodukt    abgeschieden und       getrockn    et.



  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> moles of the trisazo dye obtained by combining a molecule of 1,3-diaminobenzene-4-sulfonic acid with <B> 1 < / B> mol of the diazotized disazo dye from diazo- tated 2-Amiiioiiaphtbalin-4,

  8-disulfonic acid and <B> 1 </B> amino-S-methylberizole, further diazo- ting and combining with a second molecule of 1-amino-S-methylbeiizole, acylated with 2 moles of benzoylochloride in the presence of a tertiary base.



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



  <I> Example: </I> <B> 1 </B> mol of the trisazo dye, which is obtained by combining the 1,3-diaminobenzene-4-stilphotic acid with the diazotized di8azo dye from diazotized 2-aminoinaphthalene-4, 8-disulfonic acid and 1-amino-3-methylbenzene, further diazotizing and combining with <B> 1 </B> mol of 1-amino-B-methylbenzene,

      is dissolved in <B> 10 </B> to 15 times the amount of pyridine and mixed with 2 mol of benzoyl chloride at 400. The temperature is gradually increased to <B> 900 </B> and held for one hour. After this time, the dibenzoyl product is deposited and getrockn et.
