Description

  

  Zusatzpatent zum Hauptpatent Nr. 205164.    Verfahren zur Herstellung eines neuen Derivates eines     Azofarbstoifes.       Es wurde gefunden, dass man ein neues  Derivat eines     Azofarbstoffes    erhält, wenn  man 1     Mol    des     Trisazofarbstoffes,    der erhal  ten wird durch Vereinigen eines Moleküls  der     1,3-Diaminobenzol-4-sulfonsäure    mit 1     Mol     des     diazotierten        Disazofarbstoffes    aus     diazo-          tierter        2-Aminonaphthalin-4,8-disulfonsäure     und     Aminobenzol,

          Weiterdiazotieren    und Ver  einigen mit einem zweiten     Mol        Aminobenzol,     mit 2     Mol        Benzoylchlorid    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     Trisazofarbstoffes,    der erhalten  wird durch Vereinigen der     1,3-Diaminobenzol-          4-sulfonsäure    mit dem     diazotierten        Disazo-          farbstoff    aus     diazotierter        2-Aminonaphtbalin-          4,8-disulfonsäure    und     Aminobenzol,        Weiter-          diazotieren    und Vereinigen mit     Aminobenzol,

       wird in 3 bis 5     TAilen        Pyridin    suspendiert    und bei 400 mit 1 Teil     Benzoylchlorid    ver  setzt. Man erwärmt allmählich auf<B>900</B> und  hält diese Temperatur     11/z    Stunden. Nach  dieser Zeit wird das     Dibenzoylprodukt    abge  schieden und getrocknet.



  Additional patent to the 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 a molecule of 1,3-diaminobenzene-4-sulfonic acid with 1 mole of the diazotized disazo dye from diazo- tated 2- Aminonaphthalene-4,8-disulfonic acid and aminobenzene,

          Further diazotization and some with a second mole of aminobenzene, 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 tones.



  <I> Example: </I> 1 part of the trisazo dye obtained by combining 1,3-diaminobenzene-4-sulfonic acid with the diazotized disazo dye from diazotized 2-aminonaphthalene-4,8-disulfonic acid and aminobenzene, next - diazotize and combine with aminobenzene,

       is suspended in 3 to 5 TAilen of pyridine and sets ver at 400 with 1 part of benzoyl chloride. The mixture is gradually heated to <B> 900 </B> and this temperature is maintained for 11/2 hours. After this time, the dibenzoyl product is separated out and dried.
