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 diazotier- tem 4-Chlor-2-amino-l-phenol mit Acetessig- o-anisididsulfosäure erhalten wird, mit Chromformiat behandelt. Der neue Farbstoff bildet ein braunrotes Pulver, löst sich in Wasser mit orangegelber Farbe und färbt Wolle aus saurem Bade in sehr gleichmässi gen, echten gelborangen Tönen an.
Beispiel: 50 Teile des Farbstoffes aus 4-Chlor-2- dia.zo-l-phenol und Acetessig-o-anisididsulfo- säure (letztere wird erhalten durch Sulfieren des Acetessig-o-anisidids) werden in 1000 Teilen Wasser gelöst und bei Siedetempera- tur mit 24 Teilen Chromformiat behandelt. Sobald die Farbstoffbildung beendet ist, wird 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 diazotized 4-chloro-2-amino-1-phenol with acetoacetic-o-anisididesulfonic acid, is treated with chromium formate. The new dye forms a brown-red powder, dissolves in water with an orange-yellow color and colors wool from an acid bath in very even, genuine yellow-orange tones.
Example: 50 parts of the dye from 4-chloro-2-dia.zo-l-phenol and acetoacetic-o-anisididesulphonic acid (the latter is obtained by sulphonating acetoacetic-o-anisidide) are dissolved in 1000 parts of water and at the boiling point - treated with 24 parts of chromium formate. As soon as the dye formation is complete, it is precipitated with common salt.
