Description

  

  <B>Zusatzpatent</B> zum Hauptpatent     Nr:    156120.    Verfahren zur Herstellung eines     indigoiden        Farbstoffes    der     Anthrachinonreihe.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     indigoiden     Farbstoffes der     Anthrachinonreihe,    dadurch  gekennzeichnet, dass man ein ? .     1-Naphtoxy-          thiophenanil    mit     Anthra.chinon-1    .     2-oxythio-          phen    kondensiert.  



  Das dunkelbraun gefärbte Pulver löst  sich in konzentrierter Schwefelsäure mit  blaugrüner Farbe. Aus der gelbroten     güpe          färbi,    dieser Farbstoff Baumwolle braun.  



       Beispiel:     80 Teile 2.     1-Naphtoxythiophen-2'-(p-di-          iiiethylamino)-anil    werden in etwa 2000     Tei-          Ien    Eisessig mit 70 Teilen     Anthraehinon-          1    .     ?-oxythiohhen    6 bis 7 Stunden auf<B>100</B>    bis 105   erhitzt. Der Farbstoff wird ab  gesaugt und getrocknet.



  <B> Additional patent </B> to main patent no: 156120. Process for the production of an indigoid dye of the anthraquinone series. The present patent relates to a process for the preparation of an indigoid dye of the anthraquinone series, characterized in that one? . 1-naphthoxy-thiophenanil with anthraquinone-1. 2-oxythiophene condensed.



  The dark brown colored powder dissolves in concentrated sulfuric acid with a blue-green color. From the yellow-red güpe färbi, this dye is cotton brown.



       Example: 80 parts of 2. 1-naphthoxythiophene-2 '- (p-di-iiethylamino) -anil are mixed with about 2,000 parts of glacial acetic acid with 70 parts of anthraquinone-1. ? -oxythiohhen heated to <B> 100 </B> to 105 hours for 6 to 7 hours. The dye is sucked off and dried.
