Description

  

  Verfahren zur Herstellung eines stickstoffhaltigen     Küpenfarbstoffes     der     Anthrachinonreihe.       Vorliegendes Patent bezieht sich auf ein       Verfahren    zur Herstellung eines stickstoff  haltigen     Küpenfarbstoffes    der     Anthrachinon-          reihe,    dadurch gekennzeichnet, dass man  1     Mol    des Kondensationsproduktes, das durch  Einwirkung eines sauren Kondensationsmit  tels auf das Kondensationsprodukt von       1-Chloranthron    mit     CTlyoxalsulfat    erhalten       wird,

      mit ?     Mol        1-Aminoanthrachinon    um  setzt.  



  Der neue Farbstoff löst sich -in     konzen-          trirrter    Schwefelsäure mit     dichroitisch    grün  blauer     Farbe.    die auf Zusatz von     Paraform-          aldehyd    nach     Reinblau        umschlägt.    Er lässt  sich leicht mit braunvioletter Farbe     verküpen     und färbt aus der     Küpe    Baumwolle in dunkel  braunen Tönen von guter Echtheit an.  



  <I>Beispiel,:</I>  48 Teile des braunen Kondensationspro  duktes aus     1-Chloranthron    und     Glyoxalsulfat     und 50 Teile     a-Aminoanthrachinon    werden  zusammen mit 20 Teilen Pottasche und  5     Teilen    feinem Kupferoxyd in 500 Teilen       Naplitbalin    etwa 8 Stunden auf     200    bis    210   C erhitzt. Nach dem Verdünnen mit  etwa 500 Teilen Chlorbenzol und Auswaschen  erhält man ein dunkelrotbraunes Kristall  pulver.



  Process for the production of a nitrogenous vat dye of the anthraquinone series. The present patent relates to a process for the production of a nitrogen-containing vat dye of the anthraquinone series, characterized in that 1 mol of the condensation product obtained by the action of an acidic condensation agent on the condensation product of 1-chloranthrone with C-lyoxal sulfate is obtained,

      With ? Mol of 1-aminoanthraquinone sets.



  The new dye dissolves in concentrated sulfuric acid with a dichroic green-blue color. which changes to pure blue upon the addition of paraformaldehyde. It can be easily vetted with a brown-violet color and dyes cotton in dark brown shades of good fastness from the vat.



  <I> Example: </I> 48 parts of the brown condensation product from 1-chloroanthrone and glyoxal sulfate and 50 parts of a-aminoanthraquinone together with 20 parts of potash and 5 parts of fine copper oxide in 500 parts of naplitbalin for about 8 hours for 200 to 210 C heated. After dilution with about 500 parts of chlorobenzene and washing out, a dark red-brown crystal powder is obtained.

PATENTANSPRUCH: Verfahren zur Herstellung eines stick stoffhaltigen Küpenfarbstoffes der Anthra- chinonreihe, dadurch gekennzeichnet, dass man 1 Mol des Kondensationsproduktes, das durch Einwirkung eines sauren Kondensa tionsmittels auf das Kondensationsprodukt von 1-Chloranthron mit Glyoxalsulfat erhal ten wird, mit 2 Mol 1-Aminoanthrachinon umsetzt. PATENT CLAIM: A process for the production of a nitrogen-containing vat dye of the anthraquinone series, characterized in that 1 mol of the condensation product, which is obtained by the action of an acidic condensation agent on the condensation product of 1-chloranthrone with glyoxal sulfate, is added to 2 mol of 1-aminoanthraquinone implements. Der neue Farbstoff löst sich in konzen trierter Schwefelsäure mit dichroitisch grün blauer Farbe, die auf Zusatz von Paraform- aldehyd nach Reinblau umschlägt. Er lässt sich leicht mit braunvioletter Farbe verküpen und färbt aus der Küpe Baumwolle in dunkel braunen Tönen von guter Echtheit an. The new dye dissolves in concentrated sulfuric acid with a dichroic green-blue color that changes to pure blue when paraformaldehyde is added. It can be easily vetted with a brown-violet color and dyes cotton in dark brown shades of good fastness from the vat.
