Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>200369.</B>    Verfahren zur Herstellung eines     Küpenfarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Küpenfarb-          stoffes,    dadurch gekennzeichnet,     dass    man ein  funktionelles Derivat der     Azobeiizol-B.ss'-          dicarbonsäure    mit     1-Ainitio-5-benzoylauaino-          anthrachinon    im     Molekularverhältnis   <B>1:</B> 2 kon  densiert.  



  Der so erhaltene Farbstoff löst sich in kon  zentrierter Schwefelsäure mit brauner Farbe  und färbt Baumwolle aus dunkelroter     Küpe     in echten gelben Tönen.  



  <I>Beispiel:</I>  <B>27</B> Teile     Azobenzol-3.3'-diearbonsäure     werden durch Kochen mit<B>30</B> Teilen     Thionyl-          chlorid    in etwa 200 Teilen     o-Dichlorbenzol     in das     Säuredichlorid    übergeführt. Die vom  überschüssigen     Thionylehlorid    befreite Lösung  desselben wird in eine auf etwa<B>160 0 0</B> er  wärmte Lösung von<B>70</B> Teilen 1-Amino-6-         benzoylaminoanthrachinon    in     o-Dichlorbenzol     eingetragen und das Gemisch mehrere Stun  den unter     Rückflusskühlung    gekocht. Das ge  bildete Kondensationsprodukt wird abgesaugt,  gewaschen und getrocknet.



  Additional patent to main patent no. <B> 200369. </B> Process for the production of a vat dye. The present patent relates to a process for the production of a vat dye, characterized in that a functional derivative of azobeiizole-B.ss'-dicarboxylic acid is mixed with 1-Ainitio-5-benzoylauaino-anthraquinone in a molecular ratio <B> 1: </ B> 2 condensed.



  The dye thus obtained dissolves in concentrated sulfuric acid with a brown color and dyes cotton from a dark red vat in real yellow shades.



  <I> Example: </I> <B> 27 </B> parts of azobenzene-3.3'-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, heated to about 160 0 0, of 70 parts of 1-amino-6-benzoylaminoanthraquinone in o-dichlorobenzene and the mixture boiled under reflux for several hours. The condensation product formed is filtered off, washed and dried.
