Description

  

  Zusatzpatent zum Hauptpatent     Nr.    208546.    Verfahren zur Herstellung eines     Antbrachinonderivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines neuen  Wollfarbstoffes der     Anthrachinonreihe,    wel  ches dadurch gekennzeichnet ist,     dass    man       4-p-Anisidino-4'-methylamino-l.        l'-dianthra-          chinonylamin        mit        30        %igem        Oleum        bei        einer     Temperatur von 550 bis<B>600</B> ungefähr eine  halbe Stunde behandelt.

   Die so erhaltene       Sulfosäure    färbt Wolle in grüngrauen Tönen  an. Der Farbstoff zeichnet sich durch ein  gutes     Egalisierungsvermögen    aus.  



  <I>Beispiel:</I>  <B>8</B> Gewichtsteile     4-p-Anisidino-4#-methyl-          amino   <B>- 1. l'-</B>     dianthrachinonylamin    (erhältlich  aus     1-Methylamino-4-bromanthrachinon    und       1-Amino-4-p-anisidinoantbrachinon    durch     An-          thrimidschmelze)    werden in der zehnfachen  Gewichtsmenge     30"/oigem        Oleums    gelöst und    bei<B>50</B> bis<B>60 0 0</B> 1/2 Stunde verrührt. Die       Sulfonsäure    färbt Wolle in grüngrauen Tönen  an. Der Farbstoff zeichnet sich durch ein  gutes     Egalisierungsvermögen    aus.



  Additional patent to main patent no. 208546. Process for the production of an antbrachinone derivative. The present patent is a process for the preparation of a new wool dye of the anthraquinone series, wel Ches is characterized in that one 4-p-anisidino-4'-methylamino-l. Treated l'-dianthraquinonylamine with 30% oleum at a temperature of 550 to <B> 600 </B> for about half an hour.

   The sulfonic acid obtained in this way stains wool in green-gray tones. The dye is distinguished by its good leveling capacity.



  <I> Example: </I> <B> 8 </B> parts by weight of 4-p-anisidino-4 # -methyl- amino <B> - 1. l'- </B> dianthraquinonylamine (obtainable from 1-methylamino -4-bromoanthraquinone and 1-amino-4-p-anisidinoantbrachinone by anthrimide melt) are dissolved in ten times the amount by weight of 30% oleum and at <B> 50 </B> to <B> 60 0 0 </ B Stirred for> 1/2 hour. The sulfonic acid dyes wool in green-gray tones. The dye is characterized by good leveling properties.
