Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>200369.</B>    Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Küpenfarb-          stoffes,    dadurch gekennzeichnet,     dass    man ein  funktionelles Derivat der     Azoxybenzol-4.4'-          dicarbonsäure    mit     1-Amino-5-benzoylamino-          anthrachinon    im     Molekularverhältnis   <B>1</B>     -.    2 kon  densiert.  



  Der so erhaltene Farbstoff löst sich in  konzentrierter Schwefelsäure mit orangeroter  Farbe und färbt Baumwolle aus dunkelroter       Küpe    in sehr echten gelben Tönen von her  vorragender Licht- und Wetterechtheit.  



  <I>Beispiel:</I>  <B>29</B> Teile     Azoxybenzol-4.4'-diearbonsäure     werden durch Kochen mit<B>30</B> Teilen     Thionyl-          chlorid    in etwa 200 Teilen     o-Dichlorbenzol     in das     Säuredichlorid    übergeführt. Die vom  überschüssigen     Thionylohlorid    befreite Lösung  desselben wird in eine auf<B>160-180 C</B> er  wärmte Lösung von<B>70</B> Teilen 1-Amino-5-         benzoylaminoanthrachinon    eingetragen und  das Gemisch mehrere Stunden unter     Rück-          flusskühlung    gekocht. Das ausgeschiedene  Kondensationsprodukt wird abgesaugt, gewa  schen und getrocknet.



  Additional patent to main patent no. <B> 200369. </B> Process for the production of a pebble dye. The present patent relates to a process for the production of a vat dye, characterized in that a functional derivative of azoxybenzene-4,4′-dicarboxylic acid is mixed with 1-amino-5-benzoylamino-anthraquinone in the molecular ratio <B> 1 </B> - . 2 condensed.



  The dye obtained in this way dissolves in concentrated sulfuric acid with an orange-red color and dyes cotton from a dark red vat in very genuine yellow shades with excellent light and weather fastness.



  <I> Example: </I> <B> 29 </B> parts of azoxybenzene-4,4'-diacid are converted into the acid dichloride by boiling with <B> 30 </B> parts of thionyl chloride in about 200 parts of o-dichlorobenzene convicted. The solution of the same, freed from the excess thionyl chloride, is introduced into a solution of 70 parts of 1-amino-5-benzoylaminoanthraquinone heated to 160-180 ° C., and the mixture is reused for several hours - Boiled river cooling. The precipitated condensation product is filtered off, washed and dried.
