Description

  

  Verfahren zur     Darstellung    eines Farbstoffes der     Anthraehinonreihe.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines Farb  stoffes der     Anthrachirionreihe,    welches darin  besteht, dass man     1-Amino-2-methyl-4-(p'-          aminophenyl)-aminoanthrachinon        mitÄthylen-          chlorhydrin    in Gegenwart eines säurebinden  den Mittels zum Sieden erhitzt.

      <I>Beispiel:</I>  100 Teile     1-Amino-2-methyl-4-(p'-amino-          phenyl)-aminoanthrachinon    werden mit 500  Teilen     Äthylenchlorhydrin    und 30 Teilen       Natriumacetat    eine halbe Stunde zum Sieden  erhitzt. Nach Eingabe in Wasser scheiden  sich dunkelblaue Flocken ab, die abgesaugt  und gewaschen werden. Der so erhaltene Farb  stoff färbt     Acetatseide    in klaren, graublauen  Tönen.



  Process for the preparation of a dye of the anthraquinone series. The subject of the present patent is a process for the preparation of a dye of the anthrachirion series, which consists in boiling 1-amino-2-methyl-4- (p'-aminophenyl) -aminoanthraquinone with ethylene chlorohydrin in the presence of an acid-binding agent heated.

      <I> Example: </I> 100 parts of 1-amino-2-methyl-4- (p'-aminophenyl) -aminoanthraquinone are heated to boiling with 500 parts of ethylene chlorohydrin and 30 parts of sodium acetate for half an hour. After adding it to water, dark blue flakes separate, which are suctioned off and washed. The dye obtained in this way dyes acetate silk in clear, gray-blue tones.
