Description

  

      Zusatzpatent    zum Hauptpatent Nr. 192366.    Verfahren zur Herstellung eines neuen     Azofarbstoifes.       Es wurde     gefunden,    dass man einen neuen       Azofarbstoff    erhält, wenn man     @diazotiertes          1-Amino-2    .     5-diäthoxy-4-benzoylaminobenzol     mit dem     Arylid    aus 2 .     3-Oxynaphthoesäure     und     1-Amino-2-methoxy-4-acetobenzol    ver  einigt.  



  Der neue Farbstoff bildet ein blaues, in  Wasser unlösliches Pulver. Auf geeigneten       Substraten,    z. B. Baumwolle,     hergestellt,     färbt er diese in leuchtend violetten Tönen.  <I>Beispiel:</I>  30 Teile     1-Amino    - 2 . 5 -     diäthoxy-4-ben-          zoylaminobenzol    werden in üblicher Weise       diazotiert,    .die     erhaltene    klare     Diazolösung     wird in eine Lösung, bestehend aus 30,5 Tei  len 2.

   3 -     Oxynaphthoesäure    - 2' -     methoxy-4'-          acetoanilid,    60 Teilen     30%iger    Natrium-         hydroxydlösung,    15 Teilen     Natriumacetat     und 2000 Teilen     Wasser    eingetragen. Der  gebildete Farbstoff fällt sofort aus. Der  blaue Niederschlag wird filtriert und ge  trocknet.



      Additional patent to main patent no. 192366. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if @diazotized 1-amino-2. 5-diethoxy-4-benzoylaminobenzene with the arylide from 2. 3-oxynaphthoic acid and 1-amino-2-methoxy-4-acetobenzene united ver.



  The new dye forms a blue, water-insoluble powder. On suitable substrates, e.g. B. Cotton, produced, he dyes them in bright purple tones. <I> Example: </I> 30 parts 1-amino - 2. 5 - diethoxy-4-benzoylaminobenzene are diazotized in the usual way, the clear diazo solution obtained is converted into a solution consisting of 30.5 parts 2.

   3 - Oxynaphthoic acid - 2 '- methoxy-4'-acetoanilide, 60 parts of 30% sodium hydroxide solution, 15 parts of sodium acetate and 2000 parts of water are added. The dye formed precipitates immediately. The blue precipitate is filtered and dried.
