Description

  

  Verfahren     zur    Darstellung eines neuen     Farbstoffes    der     Anthraehinonreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Darstellung eines neuen Farb  stoffes der     Anthrachinonreihe    und ist da  durch     gekennzeichnet,    dass man     1,4-Di-(2',4'-          dimethyl)    -     phenylamino    - 6 -     chloranthrachinon          chloriert    und die erhaltene     Verbindung        sul-          fiert.     



  <I>Beispiel:</I>  15 Teile     1,4-Di-(2',4'-dimethyl)-phenyl-          amino-6-chloranthrachinon    werden in 400 Tei  len Chlorbenzol verrührt. Nach Zugabe von  0,2 Teilen Jod werden 10 Teile     Sulfuryl-          chlorid        zugetropft.    Man lässt     nun    bei 40      rühren, bis die Reaktion beendet ist. Das  Chlorbenzol wird dann mit Wasserdampf ab  geblasen und die Farbbase durch Filtration  abgetrennt.  



  5 Teile der     getrockneten    Base werden in  15     Teilen        Schwefelsäuremonohydrat    gelöst,  mit 10 Teilen     Oleüm    28 % versetzt und so  lange bei 40   gerührt, bis eine Probe in Was  ser klar löslich ist. Der Farbstoff wird auf  übliche Weise, z. B.     Eingiessen    in Salz  lösung, abgetrennt und getrocknet.  



  Der Farbstoff besitzt die Formel  
EMI0001.0025     
    und färbt Wolle in schönen blauen Tönen.



  Process for the preparation of a new dye of the anthraehinone series. The present patent relates to a process for the preparation of a new dye of the anthraquinone series and is characterized by the fact that 1,4-di- (2 ', 4'-dimethyl) - phenylamino - 6 - chloranthraquinone is chlorinated and the compound obtained is sul - celebrated.



  <I> Example: </I> 15 parts of 1,4-di- (2 ', 4'-dimethyl) -phenyl-amino-6-chloroanthraquinone are stirred in 400 parts of chlorobenzene. After adding 0.2 part of iodine, 10 parts of sulfuryl chloride are added dropwise. The mixture is now allowed to stir at 40 until the reaction has ended. The chlorobenzene is then blown off with steam and the color base is separated off by filtration.



  5 parts of the dried base are dissolved in 15 parts of sulfuric acid monohydrate, 10 parts of 28% oleum are added and the mixture is stirred at 40 until a sample is clearly soluble in what water. The dye is applied in a conventional manner, e.g. B. Pouring into saline solution, separated and dried.



  The dye has the formula
EMI0001.0025
    and dyes wool in beautiful blue tones.
