Description

  

      Zusatzpatent    zum Hauptpatent Nr. 119986.    verfahren zur Herstellung eines neuen     Farbstoffes.       Im Hauptpatent Nr. 119986 ist ein neues  Halogenderivat des     Dibenzanthrons        besehrie-          ben,    das sich von den bereits bekannten Ha  logenderivaten des     Dibenzanthrons    durch  den blauen Farbton und durch die Wasser  echtheit seiner Baumwollfärbungen aus  zeichnet.  



  Es wurde nun gefunden, dass es auch       gelingt,    durch Behandeln des     Dibenzanthrons          finit    so viel     Ferrichlorid,    dass' das erhaltene  chlorhaltige Produkt die Baumwolle aus der       Küpe    in blauen, wasserechten Tönen färbt,  einen dem Produkt des Hauptpatentes voll  ständig ebenbürtigen Farbstoff zu erhalten.  



  Der Farbstoff löst sich in konzentrierter  Schwefelsäure     violettblau;    diese Lösung, in  Wasser gegossen. fällt blaue Flocken. In  siedendem Nitrobenzol und     Trichlorbenzol     löst er sich     violettblau    mit intensiv braun  roter Fluoreszenz, in siedendem Anilin       violettstichig    blau. Die     Küpe    ist     grünstichig     blau.    <I>Beispiel:</I>  10 Teile reines     Dibenzanthron    werden  in 250 Teilen     Trichlorbenzol    suspendiert,  die Suspension unter Rühren auf 140' er  wärmt und darauf langsam 60 Teile wasser  freies Eisenchlorid eingetragen.

   Man hält  während     erogen    Stunden die Temperatur bei  140 bis<B>150'.</B> Die     Chlorierung    geht unter  starker     Salzsäuregasentwicklung    vor sich.  Die Reaktionsmasse wird dann mit Wasser  dampf behandelt, der isolierte Farbstoff mit       verdünnter    Salzsäure extrahiert, filtriert und  getrocknet. In guter Ausbeute erhält man  ein dunkelblaues     Farbstoffpulver,    welches  die Baumwolle aus der     Küpe    in blauen, nicht  wasserempfindlichen Tönen färbt..



      Additional patent to main patent no. 119986. Process for the production of a new dye. The main patent No. 119986 describes a new halogen derivative of dibenzanthrone, which is distinguished from the already known halogen derivatives of dibenzanthrone by its blue color and the waterfastness of its cotton dyes.



  It has now been found that by treating the dibenzanthrone finite enough ferric chloride that the chlorine-containing product obtained dyes the cotton from the vat in blue, water-fast tones, it is possible to obtain a dye that is completely equal to the product of the main patent.



  The dye dissolves in concentrated sulfuric acid violet blue; this solution, poured into water. falls blue flakes. In boiling nitrobenzene and trichlorobenzene it dissolves violet-blue with intense brown-red fluorescence, in boiling aniline it dissolves violet-tinged blue. The vat is blue with a green tinge. <I> Example: </I> 10 parts of pure dibenzanthrone are suspended in 250 parts of trichlorobenzene, the suspension is heated to 140 ° with stirring and then 60 parts of anhydrous iron chloride are slowly added.

   The temperature is maintained at 140 to 150 'for erogenous hours. The chlorination proceeds with vigorous evolution of hydrochloric acid gas. The reaction mass is then treated with steam, the isolated dye extracted with dilute hydrochloric acid, filtered and dried. A dark blue dye powder is obtained in good yield, which dyes the cotton from the vat in blue, water-insensitive shades.
