Description

  

  Verfahren zur Herstellung eines     indigolden        Farbstoffes    der     Aiithracenreihe.       Es wurde gefunden,     dass    man einen     in-          digoiden    Farbstoff der     Antliracenreihe    erhält,  wenn man ein     Anil    des     2,3-Anthrachinoni-          satins    mit     Oxythionaphthenkar#b#onsnure    kon  densiert und hierauf den erhaltenen Farbstoff       bromiert.    Der neue Farbstoff bildet ein rot  violettes Pulver,

   das sich in Schwefelsäure  mit grüner Farbe löst und eine     olive        Küpe     gibt, aus welcher Baumwolle     rötlichhelio-          trop    gefärbt wird.  



  <I>Beispiel</I>  <B>20,5</B> Teile des     p-Dimethylaminoanils    des       92,3-Ant'hrae,hinonisatins    werden mit<B>10</B> Tei-         len        Oxythionaplithenkarbonsäure    und<B>500</B>  Teilen     Pyridin    oder     Trichlorbenzol    zwei  Stunden unter     Rückfluss    gekocht. Der ausge  schiedene Farbstoff wird, abgesaugt, gewa  schen und getrocknet.  



  4 Teile des so erhaltenen Farbstoffes wer  den in<B>100</B> Teile     Schwefelsäuremonohydrat     eingetragen, mit<B>3</B> Teilen Brom versetzt und  sechs Stunden kalt gerührt. Hierauf wird.  die Reaktionsmasse in Wasser ausgetragen,  der abgeschiedene     bromierte    Farbstoff fil  triert und getrocknet.  



  Die Reaktion in der ersten Phase ver  läuft nach folgender Gleichung:  
EMI0001.0026     




  Process for the production of an indigolden dye of the aiithracene series. It has been found that an indigo dyestuff of the anti-liracene series is obtained if an anil of 2,3-anthraquinonisatin is condensed with oxythionaphthenic acid and the dyestuff obtained is then brominated. The new dye forms a red purple powder,

   which dissolves in sulfuric acid with a green color and gives an olive vat from which cotton is dyed reddish heliotrope.



  <I> Example </I> <B> 20.5 </B> parts of the p-dimethylaminoanil of 92,3-Ant'hrae, hinonisatins with <B> 10 </B> parts of oxythionaplithene carboxylic acid and <B > 500 parts of pyridine or trichlorobenzene boiled under reflux for two hours. The separated dye is filtered off, washed and dried.



  4 parts of the dye thus obtained are added to 100 parts of sulfuric acid monohydrate, 3 parts of bromine are added and the mixture is stirred while cold for six hours. Then will. the reaction mass discharged into water, the deposited brominated dye fil trated and dried.



  The reaction in the first phase proceeds according to the following equation:
EMI0001.0026
