Description

  

  Verfahren zur Herstellung     eines        Kiipenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden,     da.ss    man einen neuen       liiipenfarhstoff    der     Anthrachinonreilie    her  stellen kann, wenn man     1Mo1#1-Aminoanthra-          chinon    mit 1     Mol    -     3-Broni-1:2-naphtochinon     kondensiert und auf die     0-Chinongruppe    des  so erhaltenen Produktes 1     Mol        #        2:

  3-Diami-          noanthrachinon    einwirken lässt. Der so ge  wonnene     Küpenfarbstoff    bildet ein rotes Pul  ver, das sich in Nitrobenzol schwer mit ro  ter, in     Oleum    und     konz.    Schwefelsäure mit  grüner Farbe löst. Mit     Hydrosulfit    und Na  tronlauge wird eine braunrote     Küpe    erhalten,  aus welcher Baumwolle in satten, vorzüglich       echten        bordeaux    Tönen gefärbt wird.  



       Bespiel:     14 Teile     3-Brom-1:2-naphtoclhinon    werden  zusammen mit 12 Teilen     1-Ami.noantlirachi-          non,    8 Teilen entwässertem Na     triumacetat.          1;!-    Teil Kupferchlorid in 200 Teilen Eisessig  (i Stunden unter     Rückfluss    gekocht. Nach  dem Erkalten wird abgesaugt, der Rückstand  mit heissem Wasser neutral gewaschen und  getrocknet.  



  10 Teile dieses     Kondensationsproduktes          werden    zusammen mit 7 Teilen 2:3-Diainino-         antrachinon    und 500 Teilen Nitrobenzol auf  gekocht.     Nach    dem     Abkühlen    auf 100   wird  mit 20 Teilen Eisessig versetzt, eine Stunde  am     Rückflusskühler    weiter gekocht, warm  filtriert und der Rückstand,     nachdem    er mit       Alkohol    und dann mit     Wasser    nachgewaschen       worden    ist.     getrocknet.  



  Process for the preparation of a stone dye of the anthraquinone series. It has been found that a new lipene pigment of the anthraquinone range can be produced if 1Mo1 # 1-aminoanthraquinone is condensed with 1 mole of 3-bronio-1: 2-naphthoquinone and onto the 0-quinone group of the product thus obtained 1 mole # 2:

  Lets 3-diaminoanthraquinone take effect. The vat dye obtained in this way forms a red powder that is difficult to mix with red in nitrobenzene, in oleum and conc. Dissolves sulfuric acid with a green color. With hydrosulfite and sodium hydroxide solution, a brown-red vat is obtained, from which cotton is dyed in rich, exquisitely genuine burgundy tones.



       Example: 14 parts of 3-bromo-1: 2-naphtoclhinon together with 12 parts of 1-Ami.noantlirachinon, 8 parts of dehydrated sodium acetate. 1;! - part of copper chloride in 200 parts of glacial acetic acid (boiled under reflux for 1 hours. After cooling, it is filtered off with suction, the residue is washed neutral with hot water and dried.



  10 parts of this condensation product are boiled together with 7 parts of 2: 3-diainino antrachinone and 500 parts of nitrobenzene. After cooling to 100, 20 parts of glacial acetic acid are added, the mixture is boiled for a further hour on the reflux condenser, filtered warm and the residue, after it has been washed with alcohol and then with water. dried.
