Description
Zusatzpatent zum Hauptpatent Nr. <B>178548.</B> Verfahren zur Herstellung eines neuen Farbstoffes der Anthrachinonreihe. Es wurde gefunden, dass man einen neuen Farbstoff der Anthrachinonreihe erhält, wenn man auf<B>1</B> Mol Cyanurchlorid 2 Mol des Kondensationsproduktes aus 1-Amino-4- bromanthrachinon-2-sulfonsä,ure und derjeni gen Benzidinmonosulfonsäure, die erhalten wird durch Sulfieren des Benzidins,
und <B>1</B> Afol Anilin derart einwirken lässt, dass 2 Halogenatome des Cyanurchlorides mit<B>je</B> einem Wasserstoffatom der Aminogruppe des Benzidinsulfonsäurerestes des Kondensations produktes und<B>1</B> Halogenatom mit einem Wasserstoffatom der Aminogruppe des Ani lins reagieren.
Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit blauer Farbe löst und Viskosekunstseide oder Baumwolle in reinen grünstichig-blauen Tönen von sehr ,guter Liehtechtlieit färbt.
<I>Beispiel:</I> Zu einer feinen Suspension von<B>18,5</B> Tei len Cyanurchlorid in<B>800</B> Teilen Wasser wer- den bei<B>5' 113</B> Teile des Kondensations produktes aus 1-Amino-4-bromantlirachinon- 2-sulfonsäure und Benzidinsulfonsäure in 2000 Teilen Wasser zugegeben. Man rührt 4 bis<B>5</B> Stunden bei<B>10</B> bis<B>15 '</B> und erhöht dann die Temperatur allmählich auf<B>35</B> bis 40'. Durch Zutropfen einer 10%igen Na- triumearbonatlösung hält man die Reaktion stets neutral.
Wenn die Kondensation be endet ist, gibt man<B>18</B> Teile Auilin dazu und erhitzt unter gutem Rühren noch<B>1</B> Stunde auf<B>90</B> bis<B>95</B> '. Dann stellt man die Reak tionsmasse mit Natriumearbonat alkalisch und salzt den gebildeten Farbstoff aus.
Additional patent to main patent no. <B> 178548. </B> 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 2 moles of the condensation product of 1-amino-4-bromoanthraquinone-2-sulfonic acid and the benzidine monosulfonic acid are added to <B> 1 </B> mole of cyanuric chloride is obtained by sulfating the benzidine,
and <B> 1 </B> Afol allows aniline to act in such a way that 2 halogen atoms of the cyanuric chloride with <B> each </B> one hydrogen atom of the amino group of the benzidinesulfonic acid residue of the condensation product and <B> 1 </B> halogen atom with one Hydrogen atom of the amino group of the aniline react.
The new dye forms a dark powder that dissolves in water with a blue color and dyes viscose rayon or cotton in pure greenish blue tones of very, good lightness.
<I> Example: </I> For a fine suspension of <B> 18.5 </B> parts of cyanuric chloride in <B> 800 </B> parts of water, <B> 5'113 </ B> Parts of the condensation product of 1-amino-4-bromantlirachinon- 2-sulfonic acid and benzidinesulfonic acid in 2000 parts of water are added. The mixture is stirred for 4 to <B> 5 </B> hours at <B> 10 </B> to <B> 15 '</B> and then gradually increases the temperature to <B> 35 </B> to 40' . The reaction is always kept neutral by adding a 10% sodium carbonate solution.
When the condensation has ended, add <B> 18 </B> parts of Auilin and heat for <B> 1 </B> hour to <B> 90 </B> to <B> 95 <while stirring well / B> '. Then the reaction mass is made alkaline with sodium carbonate and the dye formed is salted out.
