Description

  

      Zusatzpatent    zum     Hauptpateut    Nr. 111564.     I       Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man den     Azofarb-          stoff,    welcher durch Kuppeln von     diazotier-          ter        4-Nitro-2-amino-l-phenol-6-sulfosäure    mit       Acetessiganilid    erhalten wird, mit     Chrom-          formiat    behandelt.

   Der neue Farbstoff bil  det ein braunes Pulver, löst sich in Wasser  mit gelber, in verdünnter Natronlauge mit  oranger Farbe und färbt Wolle aus saurem  Bade in sehr gleichmässigen, echten, rot  stichig gelben Tönen an.         Beispiel:     44,4 Teile des Farbstoffes, erhalten durch  Kuppeln von     4-Nitro-2-diazo-l-phenol-6-          sulfosäure    mit     Acetessiganilid,    werden einige  Zeit in wässeriger Lösung mit einer       Chromformiatlösung,    entsprechend 22,5 Tei-         len        Cr,03,    erwärmt. Die Lösung     wird    so  dann eingedampft und der Farbstoff mit  Kochsalz ausgefällt.



      Additional patent to the main patron No. 111564. I Process for the production of a new dye. It has been found that a new dye is obtained if the azo dye, which is obtained by coupling diazotized 4-nitro-2-amino-1-phenol-6-sulfonic acid with acetoacetanilide, is treated with chromium formate .

   The new dye forms a brown powder, dissolves in water with yellow, in dilute caustic soda with orange color and dyes wool from acid baths in very even, genuine, red-tinged yellow tones. Example: 44.4 parts of the dye, obtained by coupling 4-nitro-2-diazo-1-phenol-6-sulfonic acid with acetoacetanilide, are for some time in an aqueous solution with a chromium formate solution, corresponding to 22.5 parts of Cr, 03, warmed up. The solution is then evaporated and the dye is precipitated with common salt.
