  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 210608.    Verfahren zur Darstellung eines neuen, wasserlöslichen Farbstoffes  der     Anthrachinonreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Darstellung eines neuen, wasser  löslichen     Farbstoffes    der     Anthrachinonreihe     und ist dadurch gekennzeichnet, dass man  1     711o1        1,4-Diaminoanthraehinon,    2     Mol    Phenol  und 2     Mol    Formaldehyd aufeinander einwir  ken lässt und das erhaltene Produkt sulfoniert.  



  Der neue     Farbstoff    enthält zwei     Sulfogrup-          pen    und löst sich in konzentrierter Schwefelsäure  mit     blassgelber,    in Wasser mit     rotstichig    blauer  Farbe. Er soll zum Färben von     Acetatseide,          acetylierter    Baumwolle und von     Acetylcel-          lulosefolien    verwendet werden. Das Färbegut  wird in der wässerigen Lösung in rotvioletten  Tönen gefärbt.  



  <I>Beispiel:</I>  100 kg Phenol werden mit 15 kg Form  aldehyd von 40     Vol.-%    geschmolzen, bei 40   C  werden 20 kg     1,4-Diaminoanthrachinon    ein  getragen und vier Stunden weiter gerührt. Die  Schmelze wird nun in 1000 Liter Wasser ge  drückt, das 50 kg     Natriumchlorid    und 45 kg         Natriumhydroxyd    gelöst enthält. Das ausge  fallene Kondensationsprodukt wird.     abfiltriert,     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        Farbstoff,     der sich in Wasser mit     rotstichigblauer,    in       konzentrierter    Schwefelsäure mit     blassgelber     Farbe löst. Er soll zum Färben von Acetat  seide,     acetylierter    Baumwolle     und    von     Acetyl-          cellulosefolien    verwendet werden. Das Färbe  gut wird in der wässerigen Lösung in rot  violetten Tönen gefärbt.



  <B> Additional patent </B> to main patent no. 210608. Process for the preparation of a new, water-soluble dye from the anthraquinone 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 1,711o1 1,4-diaminoanthraehinone, 2 moles of phenol and 2 moles of formaldehyde are allowed to act on one another and the product obtained is sulfonated.



  The new dye contains two sulfo groups and dissolves in concentrated sulfuric acid with a pale yellow color, in water with a reddish blue color. It is said to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The dyed goods are dyed in the aqueous solution in red-violet tones.



  <I> Example: </I> 100 kg of phenol are melted with 15 kg of formaldehyde of 40% by volume, at 40 ° C. 20 kg of 1,4-diaminoanthraquinone are introduced and the mixture is stirred for another four hours. The melt is then pressed into 1000 liters of water containing 50 kg of sodium chloride and 45 kg of sodium hydroxide dissolved. 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 water with a reddish blue color, in concentrated sulfuric acid with a pale yellow color. It is said to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The dye well is colored in an aqueous solution in red violet shades.
