Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>200369.</B>    Verfahren zur Herstellung eines     Küpenfarbstoffes.       Vorliegendes Patent bezieht sieh auf ein  Verfahren zur Herstellung eines     Küpenfarb-          stoffes,    dadurch gekennzeichnet,     dass    man ein  funktionelles Derivat der     4,4'-Azoplienoxy-          essigsäure    mit     1-Amino-5-benzoylaminoan-          thrachinon    im     Molekularverhältnis   <B>1</B> :2 kon  densiert.  



  Der so erhaltene Farbstoff löst sich in  konzentrierter Schwefelsäure mit     oranger     Farbe und färbt Baumwolle aus     violettstichig     roter     Küpe    mit echten,     grünstichiggelben     Tönen.  



  <I>Beispiel:</I>  <B>18</B> Teile     4,4-Azoplienoxyessigsäuredichlo-          rid    werden mit<B>35</B> Teilen     1-Amino-5-benzoyl-          aminoanthrachinon    durch mehrstündiges Er  wärmen in     o-Dichlorbenzol    auf<B>160</B> bis<B>180'</B>  kondensiert. Nach dem Erkalten wird das       Kondensa,tionsprodukt    abgeschieden und<B>ge-</B>  trocknet.  



       4,4'-Azophenoxyess,igsä'Iaredichlorid,    das  aus Benzin in fleischfarbenen Nadeln vom  Schmelzpunkt<B>125 ' C</B> kristallisiert, kann aus    der     4,4'-Azophenoxyessigsäure    durch Ko  chen mit     Thionylchlorid    in Chlorbenzol er  halten werden.     4,4'-Azophenoxyessigsäure          lässt    sich aus der     4-NitroplienGxyessigsäure     durch alkalische Reduktion mit Trauben  zucker herstellen.



  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 producing a vat dye, characterized in that a functional derivative of 4,4'-azoplienoxyacetic acid is mixed with 1-amino-5-benzoylaminoanthrachinone in a molecular ratio of 1 / B >: 2 condensed.



  The dye thus obtained dissolves in concentrated sulfuric acid with an orange color and dyes cotton from a violet-tinged red vat with real, green-tinged yellow tones.



  <I> Example: </I> <B> 18 </B> parts of 4,4-azoplienoxyacetic acid dichloride are heated with <B> 35 </B> parts of 1-amino-5-benzoylaminoanthraquinone by heating in for several hours o-dichlorobenzene condensed to <B> 160 </B> to <B> 180 '</B>. After cooling, the condensation product is separated out and <B> </B> dried.



       4,4'-Azophenoxyess, igsä'Iaredichlorid, which crystallizes from gasoline in flesh-colored needles with a melting point <B> 125 'C </B>, can be obtained from 4,4'-azophenoxyacetic acid by boiling with thionyl chloride in chlorobenzene . 4,4'-Azophenoxyacetic acid can be produced from 4-nitropliene-gxyacetic acid by alkaline reduction with grape sugar.
