Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>160757.</B>         Yerfahren    zur Darstellung eines     wasserlösliehen        Farbstoffes    der     Anthrachinonreihe.       Das vorliegende Verfahren betrifft die  Darstellung eines wasserlöslichen Farbstoffes  der     Anthrachinonreihe    und ist dadurch ge  kennzeichnet,     dass    man     1-Benzoylamino-4-          beta-iiaphtylaminoaiithrachirioii    mit Schwefel  säure behandelt.  



  <I>Beispiel:</I>  <B>5</B> Teile     1-Benzoylamitio-4-beta-naphtyl-          aminoanthrachinon    werden bei zirka 20<B>0</B> in  <B>25</B> Teilen     Schwefelsäuremonohydrat    gelöst       und    solange gerührt, bis alles wasserlöslich  geworden ist. Der Farbstoff wird durch Ein  giessen in Wasser oder Eis, wobei er ausfällt,  und     Abfiltrieren    isoliert.  



       rn    trockenem Zustande stellt er ein dun  kelbraunes Pulver dar, welches in Wasser  leicht löslich ist und Wolle in     rotstichig     braunen Tönen, die sich durch gute     Echt-          heiten    auszeichnen, anfärbt.  



  Der Farbstoff hat wahrscheinlich folgende  Konstitution:  
EMI0001.0019     




  Additional patent to main patent no. <B> 160757. </B> Process for the preparation of a water-soluble dye of the anthraquinone series. The present method relates to the preparation of a water-soluble dye of the anthraquinone series and is characterized in that 1-benzoylamino-4-beta-iiaphtylaminoaiithrachirioii is treated with sulfuric acid.



  <I> Example: </I> <B> 5 </B> parts of 1-benzoylamitio-4-beta-naphthyl-aminoanthraquinone become <B> 0 </B> in <B> 25 </B> at around 20 Parts of sulfuric acid monohydrate dissolved and stirred until everything has become water-soluble. The dye is isolated by pouring it into water or ice, whereupon it precipitates, and filtering off.



       When dry it is a dark brown powder which is easily soluble in water and dyes wool in reddish brown tones, which are characterized by good fastness.



  The dye probably has the following constitution:
EMI0001.0019
