  Zusatzpatent zum     Hauptpatent    Nr. 253013.    Verfahren zur Herstellung     eines    neuen     Küpenfarbstoffes.       Gegenstand der vorliegenden Erfindung  ist -ein Verfahren zur     Herstellung    eines  neuen     Küpenfarbstoffes,    gemäss welchem     5-          Amino    -1,

  4-     di-p-chlorbenzoyla.niinoanthTa.chi-          non    mit einem sich von der     1-Nitroanthra-          cliinon-2-earbonsäure    ableitenden     Acylie-          rungsmittel    zur     Umsetzung    gebracht     wird.     



  Der neue Farbstoff ist ein rotes, in     konz.     Schwefelsäure     gelblichgrün    lösliches Pulver,  welches eine rotbraun gefärbte     Küpe    liefert.  



  Als     Acylierungsmittel,        welches    sich von  der     1-Nitroanthra.chinon-2-carbonsäure    ablei  tet, kann man zum Beispiel das     Acylehlorid          verwenden.     



  <I>Beispiel:</I>  53 Teile     5-Amino-1,4-di-p-chlorbenzoyl-          aminoanthrachinon,    36 Teile     1-Nitroanthra-          cliinon-2-carbonsäurechlorid    und 80 Teile o  Dichlorbenzol werden bei Siedetemperatur  während vier     Stunden    gerührt und hierauf.  gekühlt. Das Produkt wird dann     abfiltriert,          dann    mit einem     Dichlorbenzol    und hierauf    mit Benzol gewaschen, worauf es schliesslich  mit     Athanol        gewaschen    und getrocknet wird.

    Es löst sich in Schwefelsäure unter Bildung  einer     gelblichgrünen    Lösung und färbt Baum  wolle aus,     einer    rotbraunen     Küpe    in bordeaux  roten Tönen.  



  Das     5-Amino-1,4-di-p-chlorbenzoylamino-          anthrachinon        (Smp.    318 bis 319  C) wird  durch Reduktion des entsprechenden     5-Nitro-          derivates        (.Smp.    311  C)     mittels        Natriumsul-          fid        erhalten.  



  Additional patent to main patent No. 253013. Process for the production of a new vat dye. The present invention is a process for the preparation of a new vat dye, according to which 5- amino -1,

  4-di-p-chlorobenzoyla.niinoanthTa.chinon is reacted with an acylating agent derived from 1-nitroanthraclinone-2-carboxylic acid.



  The new dye is a red, in conc. Sulfuric acid yellowish-green soluble powder, which provides a red-brown colored vat.



  Acylating agent derived from 1-nitroanthraquinone-2-carboxylic acid can be used, for example, as acyl chloride.



  <I> Example: </I> 53 parts of 5-amino-1,4-di-p-chlorobenzoylaminoanthraquinone, 36 parts of 1-nitroanthraclinone-2-carboxylic acid chloride and 80 parts of dichlorobenzene are stirred at the boiling point for four hours and on this. chilled. The product is then filtered off, then washed with a dichlorobenzene and then with benzene, whereupon it is finally washed with ethanol and dried.

    It dissolves in sulfuric acid to form a yellowish-green solution and stains cotton, a red-brown vat in burgundy shades.



  The 5-amino-1,4-di-p-chlorobenzoylamino-anthraquinone (melting point 318 to 319 ° C.) is obtained by reducing the corresponding 5-nitro derivative (melting point 311 ° C.) using sodium sulfide.
