  Zusatzpatent     zum        Hauptpatent,Nr.   <B>119233.</B>    Verfahren zur Darstellung von     Isodibenzanthron.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung von     Isodibenz-          antliron.    Das Verfahren besteht darin,     dass     man     Bzl-Chlo#rtl-lioplienylbenzanthron    folgen  der Formel:  
EMI0001.0008     
    mit alkalischen Kondensationsmitteln, ins  besondere     alkoholiseliem    Alkali, behandelt.

      In eine Schmelze von     äthylalkoholischem     Kali, hergestellt durch Erhitzen von<B>100</B> Ge  wichtsteilen     Kalihyclrat    und<B>100</B> Gewichts  teilen     Äthylalkohol    auf<B>123'</B> unter     Abdestil-          lieren    des überschüssigen Alkohols, trägt man  bei<B>135</B> bis 140<B>' 25</B> Gewichtsteile     Bzl-Chlor-          thiophenylbenzantliron,    erhältlich zum Bei  spiel durch mehrstündiges Kochen von     Bzl-          Chlorbenzantliron    mit     Pottaselie,

          Chlorthio-          phenol    und     Trichlorbenzol,    ein und rührt die  Schmelze eine Stunde bei 140'. Nach dieser  Zeit verdünnt man mit Wasser, leitet in die    <I>Beispiel:</I>    Suspension Luft ein, solange noch Farbstoff  in Form der Hydroverbindung in Lösung ist,  filtriert und wäscht mit Wasser gut aus. Der  erhaltene Farbstoff, ist     Isodibenzanthron,     welches     praktiseli    vollständig frei von     Di-          benzantliron    ist.

   Er stellt ein dunkelviolettes  Pulver dar, das sieh in konzentrierter     Scbwe-          felsä,ure    mit rein grüner Farbe löst und  Baumwolle aus blauvioletter     Hydrosulfithüpe          rotstichig    violett färbt.  



  An Stelle von     Äthylalkohol    kann man  auch andere. Alkohole, an Stelle von Kali  hydrat andere     Ätzalkalien    verwenden.



  Additional patent to the main patent, no. <B> 119233. </B> Process for the preparation of isodibenzanthrone. The subject of this additional patent is a process for the preparation of isodibenzantlirone. The procedure is that you can Bzl-Chlo # rtl-lioplienylbenzanthron follow the formula:
EMI0001.0008
    treated with alkaline condensation agents, in particular alkali containing alcohol.

      In a melt of ethyl alcoholic potash, produced by heating <B> 100 </B> parts by weight of potassium cyclrate and <B> 100 </B> parts by weight of ethyl alcohol to <B> 123 '</B> while distilling off the excess Alcohol, one contributes <B> 135 </B> to 140 <B> '25 </B> parts by weight of Bzl-chlorothiophenylbenzantlirone, obtainable for example by boiling Bzl-chlorobenzantlirone with Pottaselie for several hours,

          Chlorothiophenol and trichlorobenzene, and stir the melt for one hour at 140 °. After this time, it is diluted with water, air is passed into the <I> Example: </I> suspension as long as there is still dye in the form of the hydrocompound in solution, filtered and washed thoroughly with water. The dye obtained is isodibenzanthrone, which is practically completely free of dibenzantlirone.

   It is a dark violet powder that dissolves in concentrated sulfuric acid with a pure green color and turns cotton made of blue-violet hydrosulfite hips into a reddish violet.



  Instead of ethyl alcohol you can also use others. Alcohols, use other caustic alkalis instead of potash hydrate.
