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     Phenyl-2-          naphthylamin-7-sulfonsäure    und     4-Aminodi-          äthylanilin    hergestellte     Isorosindulin-9-sulfon-          säure    mit     Bisulfit    in die     6.9-Disulfonsäure     überführt und diese mit     4'-Diäthylamino-4-          

  aminodiplienylamin-2-sulfonsäure    umsetzt.    <I>Beispiel</I>    Die in üblicher Weise aus 32     gr        Phenyl-          2-naphthylamin-7-sulfonsäure    (Na-Salz) und  17     gr        4-Aminodiäthylanilin    hergestellte     Iso-          rosindulin-9-sulfonsäure    wird mit     Bisulfit    in  die 6.

       9-Disulforisäure    übergeführt und diese in  wässeriger Lösung mit 36     gr        4'-Diäthylamino-          4-aminodiphenylainino-2-sulfonsäure(Na-Salz)     unter Zusatz von 20     gr        Natriumacetat        krist.     erwärmt. Der erhaltene     Farbstoff    der wahr  scheinlichen Formel:  
EMI0001.0029     
      löst sich in konzentrierter Schwefelsäure  grasgrün, in Wasser klar     grünstichig    blau  und färbt Wolle gut egalisierend licht- und  waschecht in sehr klaren     grünstichig    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-9-sulfonic acid prepared from phenyl-2-naphthylamine-7-sulfonic acid and 4-aminodiethylaniline is converted with bisulfite into 6.9-disulfonic acid and this with 4'-diethylamino-4-

  aminodiplienylamine-2-sulfonic acid converts. <I> Example </I> The isorosindulin-9-sulfonic acid, prepared in the usual way from 32 grams of phenyl-2-naphthylamine-7-sulfonic acid (Na salt) and 17 grams of 4-aminodiethylaniline, is converted into the 6th grade with bisulfite.

       9-disulforic acid transferred and this in aqueous solution with 36 g of 4'-diethylamino-4-aminodiphenylainino-2-sulfonic acid (Na salt) with the addition of 20 g of sodium acetate crystall. warmed up. The obtained dye of the probable formula:
EMI0001.0029
      dissolves grass green in concentrated sulfuric acid, clear greenish blue in water and dyes wool in very clear, greenish blue tones in a good leveling manner, lightfast and washable.

PATENTANSPRUCH: Verfahren zur Herstellung eines sauren Farbstoffes der Safraninreihe, dadurch ge kennzeichnet, dass man die aus Phenyl-2- naplithylamin-7-sulfonsäure und 4-Aminodi- äthylanilin hergestellte Isorosindulin-9-sul- fonsäure mit Bisulfit in die 6.9-Disulfonsäure überführt und diese mit 4'-Diäthylainino-4- aminodiphenylamin-2-sulfonsäure. umsetzt. PATENT CLAIM: Process for the production of an acidic dye of the safranine series, characterized in that the isorosindulin-9-sulphonic acid produced from phenyl-2-naplithylamine-7-sulphonic acid and 4-aminodiethylaniline is converted with bisulphite into 6.9-disulphonic acid and this with 4'-diethylainino-4-aminodiphenylamine-2-sulfonic acid. implements. Der Farbstoff löst sich in konzentrierter Schwefelsäure grasgrün, in Wasser klar grünstichig blau und färbt Wolle gut egali sierend licht- und waschecht in sehr klaren grünstichig blauen Tönen. The dye dissolves in concentrated sulfuric acid grass green, in water clear greenish blue and dyes wool in very clear greenish blue tones in a well-leveling lightfast and washfast.
