Description

  

  Verfahren zur Herstellung eines     Farbstoffes    der     Anthrachinonreihe.       Gegenstand dieses     Zusatzpatentes    ist ein  Verfahren zur Herstellung eines     Farbstoffes     der     Anthrachinonreihe,    welches dadurch ge  kennzeichnet ist, dass man     1-jodantbrachinon-          2-sulfosaures    Kalium mit     2'-amirrodiphenyl-          amin-2,4-dinitro-6-sulfosaurem    Natrium kon  densiert.  



  <I>Beispiel:</I>  14 Gewichtsteile     1-jodanthrachinon-2-sul-          fonsaures    Kalium, 13 Gewichtsteile     2'-amino-          diphenylamin-2,4-dinitro-6-su1fDnsaur-es    Na  trium, 8 Gewichtsteile     Natriumbicarbonat,     6,5 Gewichtsteile     Kupferchlorür    und 200  Gewichtsteile Wasser werden einige Stunden  bei 35-400 gerührt. Die entstandene Lö  sung wird nach dem Klären mit verdünnter  Salzsäure versetzt und der Farbstoff mit       Kaliumchlorid    ausgefällt. Man erhält ein rot  braunes Pulver, das Wolle in     gelbstichig     braunen Tönen färbt.



  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-iodantbrachinon- 2-sulfonic acid potassium is condensed with 2'-amirrodiphenylamine-2,4-dinitro-6-sulfonic acid sodium.



  <I> Example: </I> 14 parts by weight of 1-iodanthraquinone-2-sulphonate of potassium, 13 parts by weight of 2'-aminodiphenylamine-2,4-dinitro-6-sulphonate of sodium, 8 parts by weight of sodium bicarbonate, 6 , 5 parts by weight of copper chloride and 200 parts by weight of water are stirred for a few hours at 35-400. After clarification, the resulting solution is treated with dilute hydrochloric acid and the dye is precipitated with potassium chloride. A red-brown powder is obtained which dyes wool in yellowish brown tones.

PATENTANSPRUCH: Verfahren zur Herstellung eines Farb stoffes der Anthraehinonreihe, dadurch ge kennzeichnet, dass man 1-jodantbrachinon-2- sulfosaures Kalium mit 2'-aminodiphenyl- amin-2,4-dinitro-6-sulfosaurem Natrium kon densiert. Der so erhältliche Farbstoff bildet ein rotbraunes Pulver, das Wolle in gelbstichig- braunen Tönen färbt. PATENT CLAIM: Process for the production of a dye of the anthraehinone series, characterized in that 1-iodantbrachinon-2-sulfonic acid potassium is condensed with 2'-aminodiphenylamine-2,4-dinitro-6-sulfonic acid sodium. The dye that can be obtained in this way forms a red-brown powder that dyes wool in yellowish-brown tones. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Reaktionskom ponenten durch Erwärmen in Wasser in Gegenwart von Natriumbicarbonat und Kup- ferchlorür kondensiert. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that the reaction components are condensed by heating in water in the presence of sodium bicarbonate and copper chloride.
