Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 182723.    Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Es wurde gefunden, dass man einen     Küpen-          farbstoff    herstellen kann, wenn man 1     Mol          tetrachloriertes        Pyrenchinon    vom Schmelz  punkt 338   mit 1     Mol    4 .     4'-Diaminophenyl     umsetzt.  



  Der erhaltene Farbstoff stellt ein grün  schwarzes Pulver dar, das einen Schmelz  punkt von über 400   besitzt. Es löst sich  in konzentrierter Schwefelsäure mit grüner  Farbe und färbt Baumwolle aus     orangege-          färbter        Küpe    in     olivschwarzen    Tönen von  guter Waschechtheit.  



  <I>Beispiel:</I>  80 Teile     4.4'-Diaminodiphenyl,    37 Teile       Tetrachlorpyrenchinon    vom Schmelzpunkt  338   werden mit wenig Naturkupfer C und  30 Teilen     Kaliumkarbonat    vermischt und in  500 Teilen     Tetrachloräthan    suspendiert. Nun  wird die Temperatur auf 120-1250 erhöht    und während 20 Stunden weiter gerührt.  Das dunkelgefärbte Reaktionsgemisch wird  filtriert, mit     Tetrachloräthan    gewaschen und  getrocknet.



      Additional patent to the main patent No. 182723. Process for the production of a pebble dye. It has been found that a vat dye can be produced if 1 mol of tetrachlorinated pyrenquinone with a melting point of 338 is mixed with 1 mol of 4. 4'-Diaminophenyl converts.



  The dye obtained is a green-black powder that has a melting point of over 400. It dissolves in concentrated sulfuric acid with a green color and dyes cotton from an orange-dyed vat in olive-black shades of good washing fastness.



  <I> Example: </I> 80 parts of 4,4'-diaminodiphenyl, 37 parts of tetrachloropyrenequinone with a melting point of 338 are mixed with a little natural copper C and 30 parts of potassium carbonate and suspended in 500 parts of tetrachloroethane. The temperature is now increased to 120-1250 and stirring is continued for 20 hours. The dark colored reaction mixture is filtered, washed with tetrachloroethane and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Küpen- farbstoffes, dadurch gekennzeichnet, dass man 1 Mol tetrachloriertes Pyrenchinon vom Schmelzpunkt 338 mit 1 Mol 4.4'-Diamino- diphenyl umsetzt. Der erhaltene Farbstoff stellt ein grün schwarzes Pulver dar, das einen Schmelz punkt von über 400 besitzt. PATENT CLAIM: Process for the production of a vat dye, characterized in that 1 mol of tetrachlorinated pyrenequinone with a melting point of 338 is reacted with 1 mol of 4,4'-diaminodiphenyl. The dye obtained is a green-black powder that has a melting point of over 400. Es löst sich in konzentrierter Schwefelsäure mit grüner Farbe und färbt Baumwolle aus orangege- färbter Küpe in olivschwarzen Tönen von guter Waschechtheit. It dissolves in concentrated sulfuric acid with a green color and dyes cotton from an orange-dyed vat in olive-black shades of good washing fastness.
