Description
Verfahren zur Herstellung eines neuen ehromhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen wertvollen ehromhaltigen Farbstoff erhält, wenn man diazotierte 2-Amitio-l-oxybenzol- 4,6-disulfosäure mit 1-Phenyl-3-methyl-5- pyrazolon vereinigt und den erhaltenen Azo- farbstoff mit ehromabgebenden Mitteln be handelt.
Der erhaltene ehromhaltige Farbstoff stellt getrocknet ein gelbbraunes Pulver dar, löst sich in Wasser mit gelboranger, in wässeriger Natronlauge mit gelboranger, in konzentrierter Schwefelsäure mit gelber Farbe und färbt Wolle in schwefelsaurern Färbebade in sehr gleichmässigen Orangetönen von sehr guten Echtheitseigenschaften.
<I>Beispiel:</I> <B>26,9</B> Teile 2-Ainino-l-oxybenzol-4,6-disulfo- säure werden in 200 Teilen Wasser gelöst beziehungsweise suspendiert und nach Zusatz von<B>30</B> Teilen Salzsäure und Eis bei<B>0-5 0</B> wie üblich mit<B>7</B> Teilen Natriumnitrit diazo- tiert. Man lässt nun die Diazolbsung unter Rühren einlaufen in eine eiskalte Auflösung von 17,4Teilei) 1-Phenyl-3-methyl-5-pyi-azolon und<B>30</B> Teilen Natriumcarbonat in<B>300</B> Teilen Wasser.
Nach beendigter Kupplung wärmt man auf<B>60 0</B> an, salzt den Farbstoff mit Kochsalz aus, filtriert, presst und trocknet. Er bildet ein gelbstithig rotes Pulver, das sich in Wasser orangerot, in konzentrierter Schwefelsäure rein gelb löst. Wolle wird aus saurem Bade gelbbraun angefärbt; die Farbe schlägt beim Nachchromieren nach Orange rot um.
<B>95,2</B> Teile des so erhaltenen Farbstoffes werden in 2000 Teilen Wasser kochend ge löst, hernach mit 30,4 Teilen Chromoxyd, in Form einer Fluorchromlösung, versetzt und längere Zeit rückfliessend gekocht. Durch Eindampfen- und Kristallisierenlassen wird der Farbstoff gewonnen.
Process for the preparation of a new Ehrom-containing dye. It has been found that a new valuable Ehrom-containing dye is obtained if diazotized 2-amino-1-oxybenzene-4,6-disulfonic acid is combined with 1-phenyl-3-methyl-5-pyrazolone and the resulting azo dye with Ehrom-donating Funds treated.
The dyestuff containing Ehrom is a yellow-brown powder when dried, dissolves in water with yellow-orange, in aqueous sodium hydroxide solution with yellow-orange, in concentrated sulfuric acid with yellow color and dyes wool in a sulfuric-acid dyebath in very even orange tones with very good fastness properties.
<I> Example: </I> <B> 26.9 </B> parts of 2-amino-1-oxybenzene-4,6-disulphonic acid are dissolved or suspended in 200 parts of water and, after the addition of <B> 30 parts hydrochloric acid and ice at <B> 0-5 0 </B> as usual with <B> 7 </B> parts sodium nitrite diazotized. The diazole solution is now allowed to run into an ice-cold solution of 17.4 parts of 1-phenyl-3-methyl-5-pyi-azolone and 30 parts of sodium carbonate in 300 parts Share water.
When the coupling is complete, the mixture is warmed to <B> 60 0 </B>, the dye is salted out with sodium chloride, filtered, pressed and dried. It forms a yellowish red powder that dissolves orange-red in water and pure yellow in concentrated sulfuric acid. Wool is dyed yellow-brown from an acid bath; the color changes to orange red when chromium plating.
95.2 parts of the dye thus obtained are dissolved at the boil in 2000 parts of water, 30.4 parts of chromium oxide, in the form of a fluorochrome solution, are then added and the mixture is refluxed for a long time. The dye is obtained by allowing it to evaporate and crystallize.
