Description

  

  Verfahren zur Herstellung eines Farbstoffes der     Anthraehinonreihe.            Gegenstand        dieses    Zusatzpatentes ist ein  Verfahren zur Herstellung eines Farbstoffes  der     Anthrachinonreihe,    welches dadurch ge  kennzeichnet ist, dass man     1-jodanthrachinon-          2-sulfosaures    Kalium mit     3,4-Diaminochlor-          benzol    kondensiert.  



  <I>Beispiel:</I>  Zu einer     Mischung        aus    14 Gewichtsteilen       1-jodanthrachinon-2-sulfosaurem    Kalium und  4     Gewichtsteilen    Soda in 120 G     ewiehtsteilen          Wasser    wird eine Lösung von 6 Gewichts  teilen     3,4=Giaminochlorbenzol    in 15     Ge-          wichtsteilen        llolzgeist    und 0,5 Gewichts  teilen     Kupferchlorür    gegeben.

   Man erwärmt  unter Rühren auf 40 bis 45  , bis     -das    Kon  densationsprodukt sich in kleinen     braunen          Kristallen    ausgeschieden hat. Nach dem Er  kalten verdünnt man mit     Wasser,        sa;agt    ab  und wäscht mit kaltem Wasser nach. Das    Produkt färbt Wolle und Seide in echten  braunen Tönen.



  Process for the preparation of a dye of the anthraquinone series. The subject of this additional patent is a process for the production of a dye of the anthraquinone series, which is characterized in that 1-iodanthraquinone-2-sulfonic acid potassium is condensed with 3,4-diaminochlorobenzene.



  <I> Example: </I> To a mixture of 14 parts by weight of 1-iodanthraquinone-2-sulfonic acid potassium and 4 parts by weight of soda in 120 parts by weight of water is a solution of 6 parts by weight of 3,4 = giaminochlorobenzene in 15 parts by weight of alcohol and 0.5 part by weight of copper chloride.

   The mixture is heated to 40 to 45, while stirring, until the condensation product has separated out in small brown crystals. After cooling, it is diluted with water, sawn off and then washed with cold water. The product dyes wool and silk in real brown tones.
