Description
Verfahren zur Darstellung eines Farbstoffes der Anthraehinonreilre. Durch das Hauptpatent ist ein Verfahren zur Darstellung eines Farbstoffes der Anthra- chinonreihe beschrieben, das dadurch gekenn zeichnet ist, dass man 1-Amino-4-halogen- anthrachirion-2-sulforisäure mit p-Aminozimt- q äuremethylamid i umsetzt.
Gegenstand vorliegenden Patentes ist nun ein Verfahren zur Darstellung eines Farb stoffes der Anthrachinonreihe, dadurch ge kennzeichnet, dass man 1-Amino-4-halogen- anthr#acliinon-2-sulfosäure mit p-Amino-zimt- säureanilid umsetzt.
Die Reaktion wird zweckmässig in wässe riger Lösung eventuell unter Zusatz eines wasserlöslichen organischen Lösungsmittels und irr Gegenwart eines säurebindenden Mittels und eines geeigneten Katalysators durchgeführt.
Der neue Farbstoff bildet blaugrüne Na deln, die sich in Wasser mit blaugrüner Farbe lösen. Viskose wird nach den üblichen Verfahren in blaugrünen Tönen von hervor ragender Lichtechtheit angefärbt.
<I>Beispiel:</I> 10 Gewichtsteile 1-Amino-4-bromarithi#a- chinoi)-2-sulfosäure werden mit 10 Gewichts teilen p-Aminozimtsäure-anilid, 0,5 Gewichts teilen Kupferchlorür und 10 Gewichtsteilen Natriumbicarbonat in einem Gemisch von 200 Gewichtsteilen Wasser und 100 Ge wichtsteilen Alkohol etwa 3 Stunden zum Sieden erhitzt. Beim Abkühlen scheidet sich der neue Farbstoff in Form von blaugrünen Nadeln aus, welche sich in Wasser mit blaugrüner Farbe lösen und Viskose nach den üblichen Verfahren in blaugrünen Tönen von hervorragender Lichtechtheit anfärben.
Process for the preparation of a dye of the Anthraehinonreilre. The main patent describes a process for the preparation of a dye of the anthrachinone series, which is characterized in that 1-amino-4-halo-anthrachirion-2-sulforic acid is reacted with p-amino cinnamon-q acid methylamide.
The subject of the present patent is now a process for the preparation of a dye of the anthraquinone series, characterized in that 1-amino-4-halo-anthraclinone-2-sulfonic acid is reacted with p-amino-cinnamic acid anilide.
The reaction is expediently carried out in an aqueous solution, possibly with the addition of a water-soluble organic solvent and in the presence of an acid-binding agent and a suitable catalyst.
The new dye forms blue-green needles that dissolve in water with a blue-green color. Viscose is dyed in blue-green shades of excellent lightfastness according to the usual methods.
<I> Example: </I> 10 parts by weight of 1-amino-4-bromoarithi (a- quinoi) -2-sulfonic acid are combined with 10 parts by weight of p-aminocinnamic acid anilide, 0.5 parts by weight of copper chloride and 10 parts by weight of sodium bicarbonate in one Mixture of 200 parts by weight of water and 100 parts by weight of alcohol Ge heated to boiling for about 3 hours. On cooling, the new dye separates out in the form of blue-green needles, which dissolve in water with a blue-green color and dye viscose in blue-green shades of excellent lightfastness according to the usual methods.
