Description

  

      Zusatzpatent    zum Hauptpatent     Xr.    210608.    Verfahren zur Darstellung eines neuen, wasserlöslichen     Farbstoffes     der     Antlirachinonr        eihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Darstellung eines neuen, wasser  löslichen Farbstoffes der     Anthrachinonreihe     und ist dadurch gekennzeichnet, dass man  1     Mol        1,4-Diamino-2-methoxyanthraehinon,     1     Mol    Phenol und 1     Mol    Formaldehyd auf  einander einwirken lässt und das erhaltene  Produkt sulfoniert.  



  Der neue Farbstoff enthält eine     Sulfo-          gruppe,    löst sich in konzentrierter Schwefel  säure mit schwach rötlicher, in Wasser mit  rotvioletter Farbe. Er soll zum Färben von       Acetatseide,        acetylierter    Baumwolle und von       Acetyleellulosefolien    verwendet werden. Das  Färbegut wird in der wässerigen Lösung in  rosa     Tönen    gefärbt.         Beispiel:       100 kg Phenol     werden    mit 15 kg Form  aldehyd von 40 Volumenprozent geschmol  zen.

   Bei 40   C werden 20 kg     1,4-Diamino-          2    -     methoxyanthrachinon    eingetragen und  4 Stunden weiter gerührt. Die Schmelze    wird nun in 1000 Liter Wasser gedrückt, das  50 kg     Natriumchlorid    und 45 kg Natrium  hydroxyd gelöst enthält. Das ausgefallene  Kondensationsprodukt     wirdätfiltiiert,    in  Wasser aufgenommen und mit Schwefel  säure neutral gestellt. Man ,filtriert, wäscht  und trocknet. _  Durch     Sulfonieren    bei 20' C in Schwefel  säuremonohydrat erhält man einen Farb  stoff, der sich in konzentrierter Schwefel  säure mit schwach rötlicher, in Wasser mit  rotvioletter Farbe löst.

   Er soll zum Färben  von     Acetatseide,        acetylierter    Baumwolle und  von     Acetylcellulosefolien    verwendet werden.  Das Färbegut wird in der wässerigen Lö  sung in rosa Tönen gefärbt.



      Additional patent to the main patent Xr. 210608. Process for the preparation of a new, water-soluble dye of the antlirachinone series. The present patent relates to a process for the preparation of a new, water-soluble dye of the anthraquinone series and is characterized in that 1 mole of 1,4-diamino-2-methoxyanthraehinone, 1 mole of phenol and 1 mole of formaldehyde are allowed to act on each other and the result is Sulfonated product.



  The new dye contains a sulfo group, dissolves in concentrated sulfuric acid with a slightly reddish color, in water with a red-violet color. It is said to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The dyed material is dyed in pink tones in the aqueous solution. Example: 100 kg of phenol are melted with 15 kg of formaldehyde of 40 percent by volume.

   At 40 ° C., 20 kg of 1,4-diamino-2-methoxyanthraquinone are added and the mixture is stirred for a further 4 hours. The melt is then pressed into 1000 liters of water containing 50 kg of sodium chloride and 45 kg of sodium hydroxide in solution. The precipitated condensation product is filtered off, taken up in water and made neutral with sulfuric acid. It is filtered, washed and dried. _ By sulfonating at 20 ° C in sulfuric acid monohydrate, a dye is obtained which dissolves in concentrated sulfuric acid with a slightly reddish color and in water with a red-violet color.

   It is said to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The material to be dyed is dyed in pink tones in the aqueous solution.
