Verfahren zur Darstellung von walkechten gelben Disazofarbstoffen für Wolle.
In der Patentschrift Nr. 34412 sind gelbe Disazofarbstoffe beschrieben worden, die durch Kombination von tetrazotierter 4. 4'-Diaminodiphenylsulfid-2. 2'-disulfosäure (Tbio- anilindisulfosäure) mit Phenol und nachfolgender Alkylierung entstehen.
Wie gefunden wurde, erhält man aus der tetrazotierten 4. 4'-Diaminodiphenylsulfid- - 2. 2' -disulfosäure durch Kombination mit 2 Molekülen eines Acetessigs urearylids Farbstoffe, die Wolle in wesentlich lebhafteren, sehr klaren grünstichiggelben Tönen von guter Wasehund Walkechtheit anfärben.
Beispiel : 42 Teile 4. 4'-Diaminodiphenylsulfid-22'-disulfosaures Natrium werden in Wasser gelöst und nach Zusatz von 120 Teilen Salzsäure 120 Be mit 14 Teilen Natriumnitrit diazotiert. Hiezu lässt man eine Lösung von 35-5 Teilen Acetessigsäureanilid in 24 Teilen Natronlauge 400 Bd und Wasser fliessen und lässt dann Sodalösung nachlaufen, bis alkalische Reaktion eintritt. Der Farbstoff wird in der üblichen Weise aufgearbeitet.
Ähnliche Farbstoffe entstehen, wenn man im Phenylrest substituierte Acetessigsäurearylide anwendet.

Process for the preparation of milled yellow disazo dyes for wool.
Yellow disazo dyes have been described in patent specification No. 34412, which are synthesized by combining tetrazotized 4,4'-diaminodiphenyl sulfide-2. 2'-disulfonic acid (tbioanilinedisulfonic acid) with phenol and subsequent alkylation are formed.
As has been found, the tetrazotized 4,4'-diaminodiphenylsulfide- 2,2'-disulfonic acid is obtained by combining with 2 molecules of acetoacetic urearylide dyes that dye wool in much livelier, very clear greenish-yellow shades of good fastness to washing and boiling.
Example: 42 parts of 4. 4'-diaminodiphenylsulfide-22'-disulfonic acid are dissolved in water and, after addition of 120 parts of hydrochloric acid 120 Be, diazotized with 14 parts of sodium nitrite. For this purpose, a solution of 35-5 parts of acetoacetic anilide in 24 parts of 400 Bd sodium hydroxide solution and water is allowed to flow and then soda solution is allowed to run in until an alkaline reaction occurs. The dye is worked up in the usual way.
Similar dyes are formed when acetoacetic acid arylides substituted in the phenyl radical are used.
