Description

  

  Verfahren zur Herstellung eines     indigolden        Farbstoffes    der     Anthracenreihe.       Es wurde gefunden, dass     man-einen    neuen       indigoiden    Farbstoff der     Anthra-eenreihe    er  hält, wenn man das     2,3-Anthrachinonoxythi-          onap@hthen    mit     a-Is@atinanilid    kondensiert.  



  Der neue Farbstoff     ist    in     Schwefelsäure     mit grüner Farbe löslich, mit Wasser     wird:    er  in Form blauer Flocken ausgefällt. Er bildet  mit     Hydrosulfit    und Natronlauge eine olive  braune     Küpe,    aus welcher     Baumwolle    in vol  len, echten, blauen Tönen     gefärbt    wird.  



       Beispiel:     28 Teile 2,3 -     Anthrachinonoxythionaph-          tUen    und 25 Teile     a-Isatinaniliel    werden in  200 Teile     Pyridin    eingetragen und zum Sie  den erhitzt. Es tritt sofort Reaktion     ein    unter         Bildung    eines blauen Farbstoffes, der     erbfil-          triert,    gewaschen und getrocknet wird.



  Process for the production of an indigolden dye of the anthracene series. It has been found that a new indigoid dye of the Anthra-een range is obtained if the 2,3-anthraquinone oxythionophthene is condensed with α-is @ atinanilide.



  The new dye is soluble in sulfuric acid with a green color; with water it becomes: it is precipitated in the form of blue flakes. With hydrosulphite and caustic soda it forms an olive-brown vat from which cotton is dyed in full, genuine, blue tones.



       Example: 28 parts of 2,3 - anthraquinone oxythionaphthene and 25 parts of a-isatin aniliel are added to 200 parts of pyridine and heated to you. A reaction occurs immediately with the formation of a blue dye, which is filtered off, washed and dried.
