Description
Zusatzpatent zum Hauptpatent Nr. 143027. Verfaluen zur Herstellung eines neuen metallhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man die reduzierte Chromverbindung des Farbstoffes aus 5-Nitro-2-diazo-l-phenol und 2-Phenyl- amino-5-oxy naphthalin-7-sulfosäure diazotiert, mit 1,8-Dioxynaphthalin-3,6-disulfosäure kup pelt und mit chromabgebenden Mitteln be handelt.
Der erhaltene Farbstoff stellt ein dunkles -Pulver dar, das sich in verdünnter Natronlauge mit blauvioletter, in konzentrierter Schwefel säure mit schmutzig violetter Farbe löst und Viskose, sowie Naturseide in rötlichgrauen Tönen färbt.
<I>Beispiel:</I> 50 Teile des Azofarbstoffes, erhalten durch alkalische Kupplung von 32 Teilen 2-Phenyl- amino-5-oxynaphthalin-7-sulfosäure mit der Diazoverbindung aus 15 Teilen 5-Nitro-2- amino-l-pheiiol, werden mit einer aus 8,7 Teilen Cr203 enthaltenden Chromoxydhydrat- paste, 4 Teilen Ätznatron,
72 Teilen kristal- liniertem Schwefelnatrium und 14 Teilen Glyzerin hergestellten Chromlösung einige Stunden am Rückflusskübler zum lochen er hitzt. Man neutralisiert nach dem Erkalten mit Essigsäure und filtriert. Nach dem Lösen in Natronlauge wird in üblicher Weise dia- zotiert.
Die Suspension der Diazoverbindurig wird hierauf unter Eiskühlung in eine alkalische Lösung von 32 Teilen 1,8 - Dioxynaphthalin- 3,6-disulfosäure einlaufen gelassen. Nach be endeter Kupplung wird der Farbstoff abfil- triert, hierauf in 1500 Teilen heissem Wasser gelöst und nach Zusatz von Chromformiat, entsprechend 15 Teilen Chromoxyd, einige Stunden rückfliessend gekocht. Der schwer lösliche Farbstoff wird abfiltriert und ge trocknet.
Additional patent to main patent no. 143027. Procedure for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the reduced chromium compound of the dye is diazotized from 5-nitro-2-diazo-1-phenol and 2-phenylamino-5-oxy naphthalene-7-sulfonic acid with 1 , 8-Dioxynaphthalene-3,6-disulfonic acid kup pelt and be treated with chromium donating agents.
The dye obtained is a dark powder that dissolves in dilute sodium hydroxide solution with blue-violet, in concentrated sulfuric acid with a dirty purple color and dyes viscose and natural silk in reddish-gray tones.
<I> Example: </I> 50 parts of the azo dye, obtained by alkaline coupling of 32 parts of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid with the diazo compound from 15 parts of 5-nitro-2- amino-1- pheiiol, are mixed with a chromium oxide hydrate paste containing 8.7 parts of Cr203, 4 parts of caustic soda,
72 parts of crystalline sodium sulphide and 14 parts of glycerin-made chromium solution, heated for a few hours in a reflux tub to punch holes. After cooling, it is neutralized with acetic acid and filtered. After dissolving in sodium hydroxide solution, diazotization is carried out in the usual way.
The suspension of the diazo compounds is then allowed to run into an alkaline solution of 32 parts of 1,8-dioxynaphthalene-3,6-disulfonic acid while cooling with ice. When the coupling is complete, the dye is filtered off, then dissolved in 1500 parts of hot water and, after the addition of chromium formate, corresponding to 15 parts of chromium oxide, refluxed for a few hours. The sparingly soluble dye is filtered off and dried ge.
