  Verfahren zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde .gefunden, dass man einen     Kü-          penfarbstoff    herstellen kann, wenn man das       1,2-Thionaphthisatin,    welches erhalten wer  den kann durch Kondensieren von     1-Thio-          naphthol    mit     Oxalylchlorid,    mit der     6-Ami-          nooxythio:naphthenk.arbonsäure    kondensiert  und das so erhaltene Produkt mit     benzoylie-          renden    Mitteln behandelt.

   Der so erhaltene  .Farbstoff stellt ein dunkelrotes Pulver dar,       das    sich in Schwefelsäure mit olivgrüner  Farbe .löst; er gibt mit     Hydrosulfit    und Na  tronlauge eine gelbbraune     Küpe,    aus welcher  Baumwolle in     rotsti:chig    braunen Tönen ge  färbt wird, die beim Seifen echt werden.  



  <I>Beispiel:</I>  214 Teile 1,2     Thionaphthisatin        lind    209  Teile 6 -     Aminooxythiona.phthenk        .arbonsäure     werden in 4000 Teilen Alkohol suspendiert  und nach Zugabe von 5 Teilen Soda, zum Sie  den erhitzt. Nach kurzem Kochen ist die       Kondensation    beendet. Der in sehr     guter     Ausbeute abgeschiedene Farbstoff wird fil  triert,     gewaschen    und getrocknet.

      361 Teile des so erhaltenen Farbstoffes  und 141 Teile     Benzoylchlorid    werden mit  3000 Teilen     Pyridin    vermischt und während  mehreren Stunden zum Kochen erhitzt.     Beim     Abkühlen :scheidet sich in     guter    Ausbeute das  neue Produkt ,aus. Es wird     abfiltriert,    mit  Alkohol nachgewaschen und getrocknet.



  Process for the production of a new indigoid dye. It was found that a vat dye can be produced by using the 1,2-thionaphthisatin, which can be obtained by condensing 1-thionaphthol with oxalyl chloride with the 6-aminooxythio: naphthene carboxylic acid condensed and the product obtained in this way treated with benzoylating agents.

   The dye thus obtained is a dark red powder which dissolves in sulfuric acid with an olive green color; He gives a yellow-brown vat with hydrosulphite and sodium hydroxide solution, from which cotton is dyed in reddish brown tones that become real when soapy.



  <I> Example: </I> 214 parts of 1,2 thionaphthisatin and 209 parts of 6 - Aminooxythiona.phthenkarboxylic acid are suspended in 4000 parts of alcohol and, after adding 5 parts of soda, heated. After a short boil, the condensation has ended. The dye deposited in very good yield is filtered off, washed and dried.

      361 parts of the dye thus obtained and 141 parts of benzoyl chloride are mixed with 3000 parts of pyridine and heated to the boil for several hours. On cooling: the new product separates out in good yield. It is filtered off, washed with alcohol and dried.
