Description

  

  Verfahren zur Herstellung eines neuen     FarbstofA.       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       Acetessig-o-anisidid    erhalten wird, mit       Chromfluorid    behandelt. Der neue Farb  stoff bildet ein olives Pulver, löst sich in  Wasser mit gelber, in verdünnter Natron  lauge mit oranger Farbe und färbt Wolle  aus saurem Bade in sehr gleichmässigen, ech  ten,     rotstichig    gelben Tönen an.  



       Beispiel:     47,4 Teile des     Natronsalzes    des Farb  stoffes, erhalten durch Kuppeln von     4-Nitro-          2-diazo-l-phenol-6-sulfosäure    mit     Acetessig-          o-anisidid,    werden in 1000 Teilen Wasser  gelöst, mit einer     Chromfluoridlösung,    ent  sprechend 22,5 Teilen     Cr203,    versetzt und         einige    Zeit bei Gegenwart von 10 Teilen  Glaspulver zum Sieden erhitzt. Die     Lösung     wird hierauf durch Verdampfen konzentriert  und der Farbstoff mit Kochsalz ausgefällt.



  Method of making a new dye A. 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 acetoacetic-o-anisidide, is obtained with Chromium fluoride treated. The new dye forms an olive powder, dissolves in water with yellow, in dilute caustic soda with an orange color and dyes wool from an acid bath in very even, genuine, reddish yellow tones.



       Example: 47.4 parts of the sodium salt of the dye, obtained by coupling 4-nitro-2-diazo-1-phenol-6-sulfonic acid with acetoacetic o-anisidide, are dissolved in 1000 parts of water with a chromium fluoride solution, ent Speaking 22.5 parts of Cr203, added and heated to boiling for some time in the presence of 10 parts of glass powder. The solution is then concentrated by evaporation and the dye is precipitated with common salt.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man den Azofarbstoff, welcher durch Kup peln von diazoherter 4-Nitro-2-amino-l-phe- nol-6-sulfosäure mit Acetessig-o-anisidid er halten wird, mit Chromfluorid behandelt. Der neue Farbstoff bildet ein olives Pulver, löst sich in Wasser mit gelber, in verdünn ter Natronlauge mit oranger Farbe und färbt Wolle aus saurem Bade in sehr gleichmässi gen, echten, rotstichig gelben Tönen an. PATENT CLAIM: A process for the preparation of a new dye, characterized in that the azo dye, which is obtained by coupling diazo-tertiary 4-nitro-2-amino-l-phenol-6-sulfonic acid with acetoacetic-o-anisidide, treated with chromium fluoride. The new dye forms an olive powder, dissolves in water with yellow, in dilute caustic soda with orange color and dyes wool from acid baths in very even, genuine, reddish yellow tones.
