Description

  

  Verfahren zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde gefunden,     da.ss    ein neuer,     wert-          voller,        indigoider    Farbstoff     entstellt,        wenn     man das     2,3-Naphththi.o@indoxyl    mit     Thio-          n.aphthenchinon-p-dimethyl,amino-2-anil    kon  densiert.  



  Der neue Farbstoff stellt ein     violettblaues     Pulver dar, das sich     in    Schwefelsäure mit  rotblauer Farbe löst. Er bildet eine braun  orange     IMpe    und färbt Baumwolle in     helio-          trop    Tönen von sehr guter Echtheit.  



  <I>Beispiel:</I>  200 Teile     2,3-Naphththioindoxyl    und 282  Teile     Thion.apl@thenchinon-p-climethylamzno-          2-anil    werden in' 5000 Teilen Alkohol suspen  diert und, nachdem 5 Teile Soda     zugegeben     sind, unter Rühren zum     Kochen    erhitzt. Das  Reaktionsprodukt     scheidet    sich sofort in    braunroten     Kristallen    ab. Nach dem Erkal  ten wird filtriert, mit Alkohol gewaschen  und der in sehr     guter    Ausbeute erhaltene       Farbgtoff    getrocknet. .



  Process for the production of a new indigoid dye. It has been found that a new, valuable, indigoid dye is distorted if the 2,3-naphththi.o @ indoxyl is condensed with thion-naphthenquinone-p-dimethyl, amino-2-anil.



  The new dye is a violet-blue powder that dissolves in sulfuric acid with a red-blue color. It forms a brown-orange IMpe and dyes cotton in heliotropic shades of very good fastness.



  <I> Example: </I> 200 parts of 2,3-naphththioindoxyl and 282 parts of Thion.apl@thenchinon-p-climethylamzno- 2-anil are suspended in 5000 parts of alcohol and, after 5 parts of soda are added, under Stir heated to a boil. The reaction product separates out immediately in brownish red crystals. After cooling, it is filtered, washed with alcohol and the dye obtained in very good yield is dried. .
