Description
verfahren zur Herstellung eines o,ö -Dioxyazofarbetoffes. Gegenstand vorliegenden Patentes bildet ein Verfahren zur Herstellung eines o,o'-Di- oxvazofarbstoffes. Das Verfahren ist dadurch gekennzeichnet, dass man diazotierte 2-Amino- 4-cyclohexyl-phenol-6-sulfonsäure in alkali schem Medium mit 1-Carbomethoxyamino-7- oxynapht.halin kuppelt.
Der erhaltene neue Farbstoff stellt ein dunkles Pulver dar, das sich in Wasser mit violettblauer, in konzen trierter Schwefelsäure mit rotvioletter Farbe löst und Wolle aus saurem Bad in blauroten Tönen färbt, die beim Naehehromieren nach rotstichig grau umschlagen. Nach dem Ein- badchromierverfahren erhält man auf Wolle ein sehr gut lichteehtes rotstichiges Grau.
<I>Beispiel:</I> 54,2 Teile 2-Amino-4-cyelohexyl-phenol-6- sulfonsäure werden als Natriumsalz in 500 Teilen Wasser gelöst und nach Zusatz von 6,9 Teilen Natriumnitrit wie üblieh indirekt diazotiert. Die Diazoverbindung lässt man in eine Lösung von 45,6 Teilen 1-Carbomethoxy- amino-7-oxy-naphthalin in 500 Teilen Wasser, 22 Teilen Natronlauge 40%ig und 50 Teilen ealciniertem Natriumcarbonat bei 0 bis 5 C ; einfliessen.
Nach einigen Stunden Rühren fil triert man den fertiggebildeten Farbstoff ab und trocknet ihn.
process for the production of an o, ö -Dioxyazofarbetoffes. The present patent forms a process for the preparation of an o, o'-dioxvazo dye. The process is characterized in that diazotized 2-amino-4-cyclohexyl-phenol-6-sulfonic acid is coupled with 1-carbomethoxyamino-7-oxynapht.halin in an alkaline medium.
The new dye obtained is a dark powder that dissolves in water with violet-blue, in concentrated sulfuric acid with red-violet color and dyes wool from an acid bath in blue-red tones that turn to reddish gray when close-chromed. The single chrome plating process gives a very light, reddish gray on wool.
<I> Example: </I> 54.2 parts of 2-amino-4-cyelohexyl-phenol-6-sulfonic acid are dissolved as the sodium salt in 500 parts of water and, after addition of 6.9 parts of sodium nitrite, indirectly diazotized as usual. The diazo compound is left in a solution of 45.6 parts of 1-carbomethoxy-amino-7-oxy-naphthalene in 500 parts of water, 22 parts of 40% sodium hydroxide solution and 50 parts of alkaline sodium carbonate at 0 to 5 ° C .; flow in.
After a few hours of stirring, the finished dye is filtered off and dried.
