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     Disazofarbstoffes,    der erhalten wird  durch Vereinigen eines Moleküls der     1.3-          Diaminobenzol-4-sulfonsäure    mit 1     Mol    des  dianotierten     Monoazofarbstoffes    aus diano  tierter     2-Aminonaphthaliri-6.8-disulfonsäure     und     1-Amirio-3-metliylbenzol,

      mit 2     Mol          1-Naphthoesäurechlorid    in Gegenwart einer  tertiären Base     acyliert.     



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



  <I>Beispiel:</I>  1 Teil des     Disazofarbstoffes,    der erhalten  wird durch Vereinigen der     1.3-Diaminoberizol-          4-sulforisäure    mit dem dianotierten     Monoazo-          farbstoff    aus dianotierter     2-Aminonaphthalin-          6.8-disulfonsäure    und     1-Ainino-3-methylben-          zol,    wird in 4 Teilen     Pyridin    gelöst und bei  40   mit 1,6 Teilen     1-Napbthoesäurechlorid       versetzt. Man erwärmt allmählich auf<B>90'</B>  und hält diese Temperatur 1 Stunde.

   Nach  dieser Zeit wird das     Dinaphthoylprodukt     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 mole of the disazo dye, which is obtained by combining a molecule of 1,3-diaminobenzene-4-sulfonic acid with 1 mole of the dianotated monoazo dye from diano tated 2-aminonaphthaliri-6.8- disulfonic acid and 1-Amirio-3-methylbenzene,

      acylated with 2 moles of 1-naphthoic acid chloride in the presence of a tertiary base.



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



  <I> Example: </I> 1 part of the disazo dye which is obtained by combining the 1,3-diaminoberizole-4-sulforic acid with the dianotated monoazo dye from dianotated 2-aminonaphthalene-6.8-disulfonic acid and 1-amino-3-methylbene - zol, is dissolved in 4 parts of pyridine, and 1.6 parts of 1-naphthoic acid chloride are added at 40. The mixture is gradually heated to <B> 90 '</B> and held at this temperature for 1 hour.

   After this time the dinaphthoyl product is separated out and dried.
