Description
Verfahren zur Herstellung eines sauren Farbstoffes der Safraninreihe. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines sauren Farbstoffes der Safraninreihe. Es ist dadurch gekennzeichnet, dass man die aus o-Tolyl-(3- naplithylamin und 4-aininodiätliylanilin-3- sulfonsaurem Natrium hergestellte Isorosin- dulin-l-sulfonsäure mit Bisulfit in die 1.6- Disulfonsäure überführt und diese mit 2-
Metlioxy- 4- aniinodipherrylaniin-2-sulfonsäure umsetzt. <I>Beispiel:</I> Die aus 23,5 gi- o-Tolyl-fi-naphthylamin und 26,5 gr 4-aniinodiäthylaniiin-3-sulfon- saurem Natrium hergestellte Isorosindulin-l- sulfonsäure wird durch Behandeln mit Bisulfit in die 1.6-Disulfonsäure übergeführt,
diese wird in wässeriger oderverdünnter alkoholi scher Lösung mit 30 gr 2'-Methoxy-4- aminodiphenylamin-2-sulfonsäure unter Zu satz von 20 gr Natriumacetat krist. erwärmt. Der erhaltene Farbstoff der wahrscheinlichen Formel

löst sich in konzentrierter Schwefelsäure grasgrün, in heissem Wasser klar blau und färbt Wolle licht-, wasch- und walkecht in reinen blauen Tönen.
Process for the production of an acidic dye of the Safranin series. The subject of the present patent is a process for the preparation of an acidic dye of the safranine series. It is characterized in that the isorosindulin-1-sulfonic acid prepared from o-tolyl- (3-naplithylamine and 4-aininodiätliylanilin-3-sulfonic acid sodium is converted with bisulfite into 1,6-disulfonic acid and this with 2-
Metlioxy- 4-aniinodipherrylaniin-2-sulfonic acid converts. <I> Example: </I> The isorosindulin-l-sulfonic acid produced from 23.5 gi- o-tolyl-fi-naphthylamine and 26.5 g of 4-aniinodiethylaniiin-3-sulfonic acid is converted into by treatment with bisulfite the 1,6-disulfonic acid converted,
this is crystallized in aqueous or dilute alcoholic solution with 30 g of 2'-methoxy-4-aminodiphenylamine-2-sulfonic acid with the addition of 20 g of sodium acetate. warmed up. The obtained dye of the likely formula
EMI0001.0030
dissolves grass green in concentrated sulfuric acid, clear blue in hot water and dyes wool in pure blue tones that are lightfast, washable and whackfast.
