Description

  

  Verfahren zur Darstellung eines sauren Farbstoffes der     Anthrachinonreihe.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines  sauren Farbstoffes der     Anthrachinonreihe,     welches dadurch gekennzeichnet ist, dass     man          1-amino-4-bromanthrachinon    - 2 -     sulfosaures     Natrium mit     3-Amino-6-methogybenzyl-me-          thylsulfon    zur Umsetzung bringt.  



  <I>Beispiel:</I>  40 Gewichtsteile     1-amino-4-bromanthra-          chinon-2-sulfosaures    Natrium werden mit 28       Gewichtsteilen        3-Amino-6-methogybenzyl-me-          thylsulfon    in 200 Gewichtsteile in Gegenwart  von 4 Gewichtsteilen Soda, 20 Gewichtsteilen       Natriumbikarbonat    und 1 Gewichtsteil     Kup-          ferchlorür    mehrere Stunden auf 70 bis 85    erhitzt. Das abgeschiedene     Natriumsalz    des       Farbstoffes    wird     abgesaugt    und mit ver  dünnter Kochsalzlösung gewaschen.

   Man er  hält so einen blauen Farbstoff, der Wolle  in saurem Bade in klaren,     grünstichig    blauen  Tönen von gutem     Egalisierungsvermögen       färbt. Der Farbstoff hat folgende     Konstitu;          tionen:

       
EMI0001.0023     
         ,Das    zur Kondensation     verwendete    3  Amino-6-methogybenzyl-methylsulfon erhält  man nach dem im Beispiel des Zusatzpatentes  Nr. 184185,     Abs.2,    angegebenen Verfahren  aus dem     3-Nitro-6-methogybenzyl-chlorid.        3-          Nitro-6-methogy-benzylmethylsulfon,        .Schmp.     110 bis 111  .     3-Amino-6-methogy-benzyl-          methylsulfon,        ,Schmp.    102 bis 103  .



  Process for the preparation of an acidic dye of the anthraquinone series. The subject of the present additional patent is a process for the preparation of an acidic dye of the anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid sodium is reacted with 3-amino-6-methogybenzyl-methylsulfone .



  <I> Example: </I> 40 parts by weight of 1-amino-4-bromoanthraquinone-2-sulphonic acid sodium are mixed with 28 parts by weight of 3-amino-6-methogybenzyl-methylsulphone in 200 parts by weight in the presence of 4 parts by weight of soda, 20 parts by weight of sodium bicarbonate and 1 part by weight of copper chlorine heated to 70 to 85 hours for several hours. The precipitated sodium salt of the dye is filtered off with suction and washed with dilute sodium chloride solution.

   He holds a blue dye that dyes wool in an acid bath in clear, greenish blue tones with good leveling power. The dye has the following constitution; options:

       
EMI0001.0023
         The 3-amino-6-methogybenzyl-methylsulfone used for the condensation is obtained from the 3-nitro-6-methogybenzyl chloride according to the method given in the example of additional patent no. 184185, paragraph 2. 3- Nitro-6-methogy-benzylmethylsulfone,. Schmp. 110 to 111. 3-Amino-6-methogy-benzyl-methylsulfone,, m.p. 102 to 103.
