Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 219414.         Verfahren    zur Herstellung eines     Nüpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man 1     Mol    der nach dem Verfahren der       schweiz.    Patentschrift Nr. 208531 erhältlichen       Fluoranthendicarbonsäure    öder eines ihrer  funktionellen Derivate mit 2     Mol        1-Amino-          anthrachinon    umsetzt.  



  Der neue     Farbstoff    stellt ein gelbes Pul  ver dar, das sich in konzentrierter Schwefel  säure mit roter Farbe     löst,'-\bei    4201 unter  Zersetzung     schmilzt    und Baumwolle aus rot  brauner     Küpe    in     grünstichiggelben    Tönen von  sehr guten Echtheitseigenschaften färbt.  



  Als funktionelle Derivate der     Fluoranthen-          dicarbonsäure    werden zweckmässig ihre     Di-          halogenide,    insbesondere das     Dichlorid,    das  durch     Behandeln    der freien     Dicarbonsäure     mit z. B.     Thionylchlorid    erhältlich ist, ver  wendet.  



  Die Umsetzung erfolgt vorteilhaft durch  Erhitzen der Komponenten in     Lösungs-    oder  Verdünnungsmitteln, wie z. B.     Di-    oder Tri-         chlorbenzol,        Nitrobenzol,    Naphthalin oder  Chlornaphthalin.  



  <I>Beispiel:</I>  14,5 Teile     Fluoranthendicarbonsäure    wer  den durch Erhitzen auf 110-1200 mit 20  Teilen     Thionylchlorid    in 750 Teilen trocke  nem     o-Dichlorbenzol    in das     Säuredichlorid     verwandelt.

   Nach dem     Abdestillieren    des un  verbrauchten     Thionylchlorids    lässt man bei       15011    eine heisse Lösung von 22,3 Teilen       1-Ariiinoanthrachinon        in    350 Teilen     Dichlor-          benzol        zufliessen.    Nach     zweistündigem    Rühren  bei<B>150-1600</B> ist die     Farbstoffbildung    be  endet. Man saugt in der Wärme ab, wäscht mit       Dichlorbenzol    und     Alkohol    aus und trocknet.



  <B> Additional patent </B> to main patent no. 219414. Process for the production of a pebble dye. It has been found that a valuable vat dye can be produced by using 1 mol of the swiss method. Patent No. 208531 available fluoranthendicarboxylic acid or one of its functional derivatives with 2 moles of 1-aminoanthraquinone.



  The new dye is a yellow powder that dissolves in concentrated sulfuric acid with a red color, '- \ at 4201 melts with decomposition and dyes cotton from a red-brown vat in greenish yellow shades with very good fastness properties.



  As functional derivatives of the fluoranthene dicarboxylic acid, its dihalides, in particular the dichloride which is obtained by treating the free dicarboxylic acid with z. B. thionyl chloride is available, ver used.



  The reaction is advantageously carried out by heating the components in solvents or diluents, such as. B. Di- or trichlorobenzene, nitrobenzene, naphthalene or chloronaphthalene.



  <I> Example: </I> 14.5 parts of fluoranthendicarboxylic acid are converted into the acid dichloride by heating to 110-1200 with 20 parts of thionyl chloride in 750 parts of dry o-dichlorobenzene.

   After the unused thionyl chloride has been distilled off, a hot solution of 22.3 parts of 1-aryinoanthraquinone in 350 parts of dichlorobenzene is allowed to flow in at 15011. After stirring for two hours at <B> 150-1600 </B>, the dye formation is over. It is suctioned off in the heat, washed with dichlorobenzene and alcohol and dried.
