Description
Verfahren zur Darstellun-- eines Entwieklerfarhstoifes. Es wurde gefunden, dass ein wertvoller Entwicklerfarbstoff erhalten wird, wenn man tetrazotiertes Benzidin in molekularem Ver hältnis mit 2'- 1U' ethyl - 3'- amino - 5'- sulfo-1- phenyl-5-pyrazolon-3-kai-bonsäure zu einem Zwischenprodukt vereinigt und dasselbe in alkalischer Lösung mit 2-Amino-8-naphtol-6- sulfosäure weiter
kuppelt.
Der neue Farbstoff bildet ein braun schwarzes Pulver, das sich in Wasser mit violettbrauner, in konzentrierter Schwefel säure mit blauvioletter Farbe löst. Er färbt ungeheizte Baumwolle in violettbraunen Tönen, welche durch Diazotieren auf der Faser und nachfolgende Entwicklung mit Betanapbtol ohne wesentliche Nuancenänderung wasch echt fixiert werden.
<I>Beispiel</I> Zu der Tetrazodiphenyllösung aus 18,4 Teilen Benzidin lässt man bei 0-50 C die Lösung des Trinatriumsalzes von 31,3 Teilen 2'-Methyl-3'. animo-5'-sulfo-l-phenyl-5-pyrazo- lon-3-karbonsäure zufliessen. Sobald kein un verändertes Tetrazodiphenyl mehr nachgewie sen werden kann, gibt man die Lösung von 20 Teilen calcinierter Soda und hierauf die schwach phenolphtalein-alkalische Lösung von 23,9 Teilen 2-Amino-8-naphtol-6-sulfosäure zu.
Die Kombination ist nach wenigen Stunden beendigt. Man neutralisiert alsdann die braun violette Lösung mit Salzsäure und salzt den Farbstoff aus.
Method for the presentation of a developing tool. It has been found that a valuable developer dye is obtained if tetrazotized benzidine is used in a molecular ratio with 2'-1U 'ethyl-3'-amino-5'-sulfo-1-phenyl-5-pyrazolone-3-kai-bonic acid combined to form an intermediate and the same in alkaline solution with 2-amino-8-naphthol-6-sulfonic acid
clutch.
The new dye forms a brown-black powder that dissolves in water with a violet-brown color and in concentrated sulfuric acid with a blue-violet color. It dyes unheated cotton in violet-brown tones, which are fixed by diazotizing on the fiber and subsequent development with Betanapbtol without any significant change in shade.
<I> Example </I> The solution of the trisodium salt of 31.3 parts of 2'-methyl-3 'is added to the tetrazodiphenyl solution of 18.4 parts of benzidine at 0-50 ° C. Animo-5'-sulfo-1-phenyl-5-pyrazolone-3-carboxylic acid flow in. As soon as no more unchanged tetrazodiphenyl can be detected, the solution of 20 parts of calcined soda and then the weakly phenolphthalein-alkaline solution of 23.9 parts of 2-amino-8-naphthol-6-sulfonic acid are added.
The combination ends after a few hours. The brown-violet solution is then neutralized with hydrochloric acid and the dye is salted out.
