Description
Zusatzp.ttent zum Hauptpatent Nr. 104793. Verfahren zur Herstellung eines chrornhaltigen Azofarbstoffes. <B>C</B> Es wurde gefunden, dass ein cliromlialtiger Azofarbstoff erhalten wird, wenn man den o-Oxy--o-amiiioazofarbstoff aus fl-Naphthyl amin-N-methyl-co-sulfosäLireund4-Chlor-2-ami- no-l-phenol-5-suilfosäure mit Chromacetat behandelt.
Der so gewonnene ehromhaltige Azofarbstoff bildet ein schwärzlicher Pulver, dessen wässerige Lösungen in dünner Schicht blau und in dickerer Schicht violett erscheinen. Er färbt Wolle aus saurem Bade in grünen Farbtönen von ausgezeichneten Echtheits eigenschaften.
<I>Beispiel:</I> <B>57,1</B> Teile des Farbstoffes,<B>der</B> erhalten werden kann zum Beispiel durch Kuppeln von P-Naphthylainin-N-methyl-o.)-sulfosäure mit diazotierter 4-Chlor-2-amitio-l-pliciiol-5-sulfo- säure, werden in<B>350</B> Teilen kochendem Wasser gelöst, mit einer Chromacetatlösung, ent sprechend 11,4 Teilen Crz03, versetzt und längere. Zeit am Rüchflusskühler gekocht Hierauf wird tei.lweise eingedampft und durch Zusatz von Kochsalz die Chromverbindung ausgesalzen.
Additional patent to the main patent no. 104793. Process for the production of a chromium-containing azo dye. <B> C </B> It has been found that a cliromlialtiger azo dye is obtained if the o-oxy - o-amiiioazo dye is obtained from fl-naphthylamine-N-methyl-co-sulfosäLireand4-chloro-2-ami- no-l-phenol-5-suilfonic acid treated with chromium acetate.
The azo dye containing Ehrom thus obtained forms a blackish powder, the aqueous solutions of which appear blue in a thin layer and purple in a thicker layer. It dyes wool from an acid bath in green shades with excellent fastness properties.
<I> Example: </I> <B> 57.1 </B> parts of the dye <B> which </B> can be obtained, for example, by coupling P-naphthylamine-N-methyl-o.) sulfonic acid with diazotized 4-chloro-2-amitio-l-pliciiol-5-sulfonic acid are dissolved in 350 parts of boiling water, and a chromium acetate solution, corresponding to 11.4 parts of Crz03, is added and longer. Time is boiled on the reflux cooler. This is then partially evaporated and the chromium compound is salted out by adding table salt.
