Description

  

      Zusatzpatent    zum Hauptpatent Nr. 205169.    Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung eines sauren Farb  stoffes der     Triphenylmethanreihe,    welches  dadurch gekennzeichnet ist, dass man den       Triphenylmethanfarbstoff,    der durch     Konden-          säion    von 1     Mol        4.4'-Dichlorbenzophenon     mit 1     Mol        1-Isobutyl-2-p-chlorphenyl-4.6-          diinethylindol    erhältlich ist, mit     1-Metbyl-          amino-4-äthoxyberizolsulfonsäure    verschmilzt.

    Bei dieser Umsetzung tritt ein     Mol    des     Tri-          phenylmethanfarbstoffes    mit 2     Mol        Methyl-          aminoäthoxybenzolsulforisäure    in Reaktion.

      <I>Beispiel:</I>    Das durch Kondensation von     4.4'-Di-          chlorbenzophenon    mit     1-Isobutyl-2-p-chlor-          phenyl-4.6-dimethylindol    erhältliche Kon  densationsprodukt wird etwa 6 Stunden lang  in wässerigem     Pyridin    mit überschüssiger 1  Methylamino-4-äthoxybenzolsulfonsäure (er  hältlich durch Sulfonieren von 1-Methylamino-         4-äthoxybenzol    mit der     3fachen    Menge kon  zentrierter Schwefelsäure bei 100-120  ) bei  etwa 100  C erhitzt, bis die Blaufärbung  nicht mehr zunimmt. Der so erhaltene saure  Farbstoff färbt Wolle und Seide in blauen  Tönen.



      Additional patent to the main patent No. 205169. The subject of this additional patent is a process for the production of an acidic dye of the triphenylmethane series, which is characterized in that the triphenylmethane dye, which is produced by condensation of 1 mole of 4,4'-dichlorobenzophenone with 1 mole of 1-isobutyl -2-p-chlorophenyl-4,6-diinethylindole is available, fused with 1-methylamino-4-ethoxyberizolsulfonic acid.

    In this reaction, one mole of the triphenylmethane dye reacts with 2 moles of methylaminoethoxybenzenesulforic acid.

      <I> Example: </I> The condensation product obtainable by condensation of 4,4'-dichlorobenzophenone with 1-isobutyl-2-p-chlorophenyl-4,6-dimethylindole becomes in aqueous pyridine with excess 1 methylamino for about 6 hours -4-ethoxybenzenesulfonic acid (it can be obtained by sulfonating 1-methylamino-4-ethoxybenzene with 3 times the amount of concentrated sulfuric acid at 100-120) heated at about 100 C until the blue color no longer increases. The acidic dye thus obtained dyes wool and silk in blue tones.
