Description

  

      Zusatzpatent    zum Hauptpatent     hir.    113920.    Verfahren zur Darstellung eines     Nüpenfarbstoffes.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Küpenfarb-          stoffes    aus chloriertem     Isodibenzanthron    mit  einem Chlorgehalt von etwa 10 01o, wie es  nach dem Verfahren der deutschen Patent  schrift Nr. 217570 erhältlich ist, und     Phe-          nolen.    Das Verfahren wird beispielsweise  folgendermassen ausgeführt:

    10 Teile chloriertes     Isodibenzanthron    mit  einem Chlorgehalt von etwa 10 %, wie es  nach dem Verfahren der deutschen Patent  schrift Nr. 217570 erhältlich ist, werden mit       etwa,    80 Teilen Phenol und 8 Teilen     Ä.tz-          kali    etwa 10 Stunden unter Rühren zum  Sieden erhitzt. Die Aufarbeitung der Schmelze       kann    so erfolgen,     dass    man nach dem Ab  kühlen mit Alkohol verdünnt, absaugt, mit  Alkohol und dann mit Wasser wäscht und  trocknet.  



  Der in trockenem, pulverförmigem Zu  stande     violettschwarze    Farbstoff ist in     Al-          kalien    und Säuren unlöslich. In konzen-         trierter    Schwefelsäure löst er sich grau,  in organischen Lösungsmitteln     violett    bis  blau mit roter     Fluoreszenz.    Die     Iiydro-          sulfitküpe    ist blau. Baumwolle wird .in ihr  in echten, blauen Tönen angefärbt.



      Additional patent to the main patent hir. 113920. Process for the preparation of a pimple dye. The subject of this additional patent is a process for the preparation of a vat dye made from chlorinated isodibenzanthrone with a chlorine content of about 10 01o, as can be obtained by the process of German Patent No. 217570, and phenols. The procedure is carried out as follows, for example:

    10 parts of chlorinated isodibenzanthrone with a chlorine content of about 10%, as it is obtainable by the method of German Patent No. 217570, are heated to boiling with about 80 parts of phenol and 8 parts of caustic potash for about 10 hours while stirring . The melt can be worked up in such a way that, after cooling, it is diluted with alcohol, filtered off with suction, washed with alcohol and then with water and dried.



  The dye, which is violet-black when dry, in powder form, is insoluble in alkalis and acids. In concentrated sulfuric acid it dissolves gray, in organic solvents violet to blue with red fluorescence. The hydrosulfite vat is blue. Cotton is dyed in it in real, blue tones.
