Description

  

  Verfahren zur Darstellung eines Farbstoffes der     Anthrachiiionreihe.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Darstellung eines Farbstoffes  der     Anthrachitionreilie,    welches darin besteht,       dass    man     1-Amiiio-4-(p'-aminophenyl)-aniino-          anthrachinon    mit     Äthylerichlorhydrin    in Ge  genwart eines säurebindenden Mittels etwa  <B>8</B> Stunden zum Sieden erhitzt.  



  <I>Beispiel:</I>  <B>100</B> Teile     1-Amiiio-4-(p'-aminophenyl)-          aminoanthrachition    werden mit<B>500</B> Teilen       Äthylenchlorhydrin    und<B>30</B> Teilen     Natrium-          acetat   <B>8</B> Stunden zum Sieden erhitzt     und     dann das     Reaktionsgernisch    in Wasser ge  geben. Der erhaltene Niederschlag wird ab  gesaugt und solange mit Wasser gewaschen,  bis alles     Äthylenchlorhydrin    und     Natrium-          acetat    entfernt ist.

   Man erhält einen Farb  stoff der     Acotatseide        grünstichig    blau färbt.



  Process for the preparation of a dye of the Anthrachiiion series. The subject of the present patent is a process for the preparation of a dye of the anthraquinone route, which consists in that 1-Amiiio-4- (p'-aminophenyl) -aniino-anthraquinone with ethyl chlorohydrin in the presence of an acid-binding agent about <B> 8 </ B> hours heated to boiling.



  <I> Example: </I> <B> 100 </B> parts of 1-Amiiio-4- (p'-aminophenyl) - aminoanthraite are mixed with <B> 500 </B> parts of ethylene chlorohydrin and <B> 30 < / B> Parts of sodium acetate heated to boiling for 8 hours and then poured the reaction mixture into water. The resulting precipitate is filtered off with suction and washed with water until all of the ethylene chlorohydrin and sodium acetate have been removed.

   A dye is obtained which dyes acotate silk greenish blue.
