Description

  

  Verfahren zur     Darstellung    eines     Farbstoffes    der     Anthraehinonreihe.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Darstellung eines     Farbstoffes     der     Anthrachinonreihe,    welches darin besteht,  dass     rnau        1-Amino-4-(p'-amiriopherryl)-amino-          anthrachinon    mit     Äthylenchlorhydrin    in Ge  genwart eines säurebindenden Mittels etwa  Stunde lang zum Sieden erhitzt.  



  <I>Beispiel:</I>  100 Teile     1-Arnirio-4-(p'-aminophenyl)          aminoaritlirachinon    werden mit 500 Teilen       Äthylenchlorhydrin    und     30Teilen        Natriumace-          tat    etwa eine halbe Stunde zum Sieden erhitzt  und dann das     Reaktionsgemisch    in Wasser  gegeben. Der erhaltene blaue Niederschlag  wird abgesaugt und so lange mit Wasser ge  waschen, bis alles Ä     thylenchlorhydrin    und       Natriumacetat    entfernt ist. Dar erhaltene       Farbstoff    färbt     Acetatseide    in stahlblauen,  äusserst kräftigen 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 anthraquinone series, which consists in boiling 1-amino-4- (p'-amiriopherryl) -amino-anthraquinone with ethylene chlorohydrin in the presence of an acid-binding agent for about one hour.



  <I> Example: </I> 100 parts of 1-arnirio-4- (p'-aminophenyl) aminoaritlirachinon are heated to boiling with 500 parts of ethylene chlorohydrin and 30 parts of sodium acetate for about half an hour and then the reaction mixture is poured into water. The blue precipitate obtained is filtered off with suction and washed with water until all ethylene chlorohydrin and sodium acetate are removed. The dye obtained dyes acetate silk in extremely strong shades of steel blue.
