Description

  

  Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man den     Azofarb-          stoff,    welcher durch Kuppeln von     diazoüer-          ter        4-Chlor-2-amino-l-phenol-6-sulfosäure        mit          Acetessiganilid    erhalten wird, mit     Chrom-          fluorid    behandelt. Der neue Farbstoff bildet  ein oranges Pulver, löst sich in Wasser mit  gelber Farbe und färbt Wolle aus saurem  Bade in sehr gleichmässigen, echten gelben  Tönen an.  



  <I>Beispiel:</I>  43,1 Teile des     Natronsalzes    des Farb  stoffes, erhalten durch Kuppeln von     4-Chlor-          2-diazo-l-phenol-6-sulfosäure    mit     Acetessig-          anilid,    werden in 1000 Teilen Wasser gelöst,  mit einer     Chromfluoridlösung    entsprechend  22,5 Teilen     Crz03    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.



  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 diazoic 4-chloro-2-amino-1-phenol-6-sulfonic acid with acetoacetanilide, is treated with chromium fluoride . The new dye forms an orange powder, dissolves in water with a yellow color and dyes wool from an acid bath in very even, genuine yellow tones.



  <I> Example: </I> 43.1 parts of the sodium salt of the dye, obtained by coupling 4-chloro-2-diazo-1-phenol-6-sulfonic acid with acetoacetic anilide, are dissolved in 1000 parts of water, with a chromium fluoride solution corresponding to 22.5 parts of Crz03 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.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man den Azofarbstoff, welcher durch Kup peln von diazotierter 4-Chlor-amino-l-phe- nal-6-sulfosäure mit Acetessiganilid erhalten wird, mit Chromfluorid behandelt. Der neue Farbstoff bildet ein oranges Pul ver, löst sich in Wasser mit gelber Farbe und färbt Wolle aus saurem Bade in sehr gleichmässigen, echten gelben Tönen an. PATENT CLAIM: Process for the production of a new dye, characterized in that the azo dye, which is obtained by coupling diazotized 4-chloro-amino-1-phenal-6-sulfonic acid with acetoacetanilide, is treated with chromium fluoride. The new dye forms an orange powder, dissolves in water with a yellow color and dyes wool from an acid bath in very even, genuine yellow tones.
