Description
<B>Zusatzpatent</B> zum Hauptpatent Nr.<B>165155.</B> Verfahren zur Herstellung eines metallhaltigen Farbstoffes. Es wurde gefunden, dass man einen me tallhaltigen Farbstoff durch Behandeln des Azofarbstoffes aus diazotiertem 4-Chlor-2- amino-l-phenol und 2.4-Dioxychinolin mit chromabgebenden Mitteln in alkalischem Me dium erhalten kann, wenn diese Behandlung in Gegenwart von Salzen der Zuckersäure erfolgt.
Der erhaltene chromhaltige Farbstoff stellt ein braunrotes Pulver dar, das in Wasser sehr schwer, in organischen Lösungsmitteln leicht mit bordeauxroter Farbe löslich ist. Aras Nitro- oder Acetylzelluloselacklösungen erhält man Überzüge von braunroter Farbe. <I>Beispiel:</I> 6,30 Teile des Farbstoffes aus diazotier- tem 4-Chlor-2-amino-l-phenol und 2.4-Dioxy- chinolin werden in 500 Teilen Wasser und 2,7 Teilen 30 o/oiger Natronlauge aufgekocht.
Hierauf versetzt man mit einer Lösung aus 11,8 Teilen Chromisulfat, 15,0 Teilen zucker- saurern Kalium (CoH90sK), 60 Teilen Wasser und 24 Teilen 30 o/oiger Natronlauge und kocht während 15 Stunden am Rückfluss. Nach dem Neutralisieren mit Essigsäure wird der Farbstoff filtriert, ausgewaschen und bei mässiger Temperatur getrocknet.
<B> Additional patent </B> to main patent no. <B> 165155. </B> Process for the production of a metal-containing dye. It has been found that a metal-containing dye can be obtained by treating the azo dye from diazotized 4-chloro-2-amino-1-phenol and 2,4-dioxyquinoline with chromium donating agents in alkaline Me if this treatment is carried out in the presence of salts of sugar acid he follows.
The chromium-containing dye obtained is a brown-red powder which is very difficult to dissolve in water and easily soluble in organic solvents with a claret-red color. Ara's nitro or acetyl cellulose lacquer solutions give coatings of brown-red color. <I> Example: </I> 6.30 parts of the dye from diazotized 4-chloro-2-amino-1-phenol and 2,4-dioxyquinoline are dissolved in 500 parts of water and 2.7 parts of 30% Sodium hydroxide solution boiled.
A solution of 11.8 parts of chromium sulfate, 15.0 parts of sugar-acid potassium (CoH90sK), 60 parts of water and 24 parts of 30% sodium hydroxide solution is then added and the mixture is refluxed for 15 hours. After neutralizing with acetic acid, the dye is filtered, washed out and dried at a moderate temperature.
