Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 111564.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden; dass man einen  neuen     Farbstoff    erhält, wenn man den       Azofarbstoff,    welcher durch Kuppeln von  dianotierter     4-Nitro-l-amino-l-phenol-6-sulfo-          säure        finit        Acetessiganilid    erhalten wird, mit       Chromfluorid        behandelt.-    Der neue Farbstoff  bildet ein braunes Pulver, löst sich in Was  ser mit gelber Farbe und färbt Wolle aus  saurein Bade in sehr gleichmässigen,  echten     rötlichgelben    Tönen an.  



  <I>Beispiel:</I>  44,4 Teile des     Natronsalzes    des Farb  stoffes, erhalten durch Kuppeln von     4-Nitro-          2-diazo-l-phenol6-sulfosäure    mit     Acetessig-          anilid,    werden in 1000 Teilen Wasser ge  löst, mit einer     Chromfluoridlösung    entsprechend  22,5 Teilen     Cr20s    versetzt und einige Zeit  bei Gegenwart von 10 Teilen Glaspulver    zum Sieden erhitzt. Die Lösung wird hier  auf durch Verdampfen konzentriert und der       Farbstoff    mit Kochsalz ausgefällt.



  <B> Additional patent </B> to main patent no. 111564. Process for the production of a new dye. It was found; that a new dye is obtained if the azo dye, which is obtained by coupling of dianotated 4-nitro-1-amino-1-phenol-6-sulfonic acid finite aceto-aceticanilide, is treated with chromium fluoride. The new dye forms a brown one Powder, dissolves in water with a yellow color and stains wool from acidic bath in very even, genuine reddish-yellow tones.



  <I> Example: </I> 44.4 parts of the sodium salt of the dye, obtained by coupling 4-nitro-2-diazo-1-phenol6-sulfonic acid with acetoacetic anilide, are dissolved in 1000 parts of water with a chromium fluoride solution corresponding to 22.5 parts of Cr20s and heated to boiling for some time in the presence of 10 parts of glass powder. The solution is concentrated here by evaporation and the dye is precipitated with common salt.
