Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 178548. Verfahren zur Herstellung eines neuen Farbstoffes der Anthrachinonreihe. Es wurde gefunden, dass man einen neuen Farbstoff der Anthrachinonreihe erhält, wenn man auf 1 Mol Cyanurchlorid 2 Mol des Kondensationsproduktes aus 1-Amino-4- bromanthrachinon-2-sulfonsäure und derjeni gen Benzidinmonosulfonsäure, die erhalten wird durch Sulfieren des Benzidins,
und 1 Mol p-Aminoacetanilid derart einwirken lässt, dass zwei Halogenatome des Cyanur- ehlorids mit je einem Wasserstoffatom der Aminogruppe des Benzidinsulfonsäurerestes des Kondensationsproduktes und ein Ha logenatom mit einem Wasserstoffatom der Aminogruppe des p-Aminoacetanilids rea gieren.
Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit blauer Farbe löst und Viskosekun@stseid-e oder Baumwolle in reinen grünstichig-blauen Tönen von sehr guter Dichtechtheit färbt. <I>Beispiel:</I> Zu einer feinen Suspension von 18,5 Tei len Cyanurchlorid in 800 Teilen Wasser wer- den bei 5 118 Teile des Kondensations produktes aus 1-Amino-4-bromanthrachinon- 2-sulfonsäure und Benzidinsulfonsäure in 2000 Teilen Wasser zugegeben. Man rührt 4 bis 5 Stunden bei 10 bis 15 und erhöht dann die Temperatur allmählich auf 85 bis 40'.
Durch Zutropfen einer 10%igen Na- triumcarbonatlösung hält man die Reaktion stets neutral. Wenn die Kondensation be endet ist, gibt man 20 Teile p-Aminoacet- anilid dazu und erhitzt unter gutem Rühren noch 1 @Stunde auf 9,0 bis <B>95'.</B> Dann stellt man die Reaktionsmasse mit Natriumcarbo- nat alkalisch und salzt den gebildeten Farb stoff aus.
<B> Additional patent </B> to main patent no. 178548. Process for the production of a new dye from the anthraquinone series. It has been found that a new dye of the anthraquinone series is obtained if, for 1 mole of cyanuric chloride, 2 moles of the condensation product of 1-amino-4-bromoanthraquinone-2-sulfonic acid and the benzidine monosulfonic acid obtained by sulfating the benzidine,
and 1 mole of p-aminoacetanilide is allowed to act in such a way that two halogen atoms of the cyanuric chloride react with one hydrogen atom of the amino group of the benzidine sulfonic acid residue of the condensation product and one halogen atom with one hydrogen atom of the amino group of the p-aminoacetanilide.
The new dye forms a dark powder which dissolves in water with a blue color and dyes viscose silk or cotton in pure greenish-blue shades with very good impermeability. <I> Example: </I> A fine suspension of 18.5 parts of cyanuric chloride in 800 parts of water is converted into 118 parts of the condensation product of 1-amino-4-bromoanthraquinone-2-sulfonic acid and benzidine sulfonic acid in 2000 Parts of water are added. The mixture is stirred for 4 to 5 hours at 10 to 15 and then the temperature is gradually increased to 85 to 40 '.
The reaction is always kept neutral by adding a 10% strength sodium carbonate solution. When the condensation is over, 20 parts of p-aminoacetanilide are added and the mixture is heated to 9.0 to 95 'for 1 hour with thorough stirring. The reaction mixture is then made up with sodium carbonate alkaline and salt out the dye formed.
