Description

  

  Verfahren zur Darstellung eines     Küpenfarbstoffes.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Küpenfarb-          stoffes.    Das Verfahren ist dadurch gekenn  zeichnet, dass man das Kondensationsprodukt  aus     Dichlorperylentetrakarbonsäureanhydrid     und     o-Phenylendiamin    mit Phenol umsetzt.

    Das Verfahren kann wie folgt ausgeführt  werden:  10 Teile des violetten Kondensations  produktes aus     Dichlorperylentetrakarbon-          säureanhydiid    (wie es aus     Perylentetrakar-          bonsäureanhydrid        dureh    Chlorieren bis zur       Dichlorstufe,    beispielsweise in     Chlorsulfon-          säure,    erhalten werden kann). und     o-Phe-          nylendiamin    werden mit etwa 70 Teilen  Phenol und 7 Teilen     Kaliumkarbonat    acht  bis zehn Stunden unter Rühren zum Sieden  erhitzt.

   Die Aufarbeitung der Schmelze kann  so erfolgen, dass man nach dem Abkühlen  mit Alkohol verdünnt, absaugt, mit Alkohol  und dann mit     Wasser    wäscht und trocknet.  



  Der in trockenem, pulverförmigem Zu  stande     schwarzviolette    Farbstoff ist in     Al-          kalien    und Säuren unlöslich. In konzen-         trierter    Schwefelsäure löst er sich blaugrün,  in organischen Lösungsmitteln violett bis  blau mit braunroter Fluoreszenz. Die     Hydro-          sulfitküpe    ist blau. Auf Baumwolle erhält  man ein echtes Blau.



  Process for the preparation of a vat dye. The subject of this additional patent is a process for the preparation of a vat dye. The process is characterized in that the condensation product of dichloroperylenetetracarboxylic acid anhydride and o-phenylenediamine is reacted with phenol.

    The process can be carried out as follows: 10 parts of the violet condensation product from dichloroperylenetetracarboxylic acid anhydride (as can be obtained from perylenetetracarboxylic acid anhydride by chlorination up to the dichloro stage, for example in chlorosulfonic acid). and o-phenylenediamine are heated to boiling with about 70 parts of phenol and 7 parts of potassium carbonate for eight to ten 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 black-violet dye when dry, in powder form, is insoluble in alkalis and acids. In concentrated sulfuric acid it dissolves blue-green, in organic solvents purple to blue with brown-red fluorescence. The hydrosulfite vat is blue. On cotton you get a real blue.
