Description
Zusatzpatent zum Hauptpatent Nr. 304040. Verfahren zur Herstellung eines Azofarbstoffes. Es wurde gefunden, dass man zu einem neuen, wertvollen, metallhaltigen Azofarbstoff
EMI0001.0007
entsprechen, kobaltabgebende Mittel derart einwirken lässt, dass ein kobalthaltiger Azo- farbstoff entsteht, der je ein Molekül der zwei Ausgangsmonoazofarbstoffe an ein Kobalt atom komplex gebunden enthält.
Der neue kobalthaltige Farbstoff bildet ein dunkles Pulver, das sieh in Wasser löst und Wolle aus neutralem oder schwach essigsau rem Bade in braunen Tönen färbt.
Die zwei beim vorliegenden Verfahren als Ausgangsstoffe dienenden Monoazofarbstoffe können nach an sich bekannten Methoden her gestellt werden, indem man diazotiertes 2- Amino-l- oxybenzol - 4 - sulfonsäuremethylamid mit 1-(4'-Chlorphenyl)-3-methyl-5-pyrazolon und dianotiertes 3-Amino-4-oxy-1,1'-diphenyl- sulfon mit 1-Acetylamino-7-oxynaphthalin je weils in alkalischem Medium kuppelt.
Bei der Durchführung des Verfahrens empfiehlt es sieh im allgemeinen, auf ein ins gesamt aus etwa. 2 Mol Monoazofarbstoff be- gelangt, wenn man auf ein Gemisch der zwei Monoazofarbstoffe,
die den folgenden Formeln stehendes und je etwa 1 Mol der beiden als Ausgangsstoffe verwendeten Farbstoffe ent haltendes Gemisch eine etwa ein Grammatom Kobalt enthaltende Menge eines kobaltabge- benden Mittels zu verwenden lind/oder die Metallisierung in schwach saurem bis alkali schem Medium auszuführen.
Es sind zum Bei spiel als kobaltabgebende Mittel für die Durch- führung des Verfahrens besonders gut geeig net komplexe Kobaltverbindungen aliphati- scher o-Oxycarbonsäuren oder einfache Ko- baltsalze wie Kobaltsulfat oder Kobaltacetat.
Die Umwandlung der Farbstoffe in die komplexen Kobaltverbindungen geschieht mit Vorteil in der Wärme, offen oder unter Druck, z. B. bei Siedetemperatur des Reaktionsgemi sches, gegebenenfalls in Anwesenheit geeigne ter Zusätze, z. B. in Anwesenheit von Salzen organischer Säuren, von Basen, organischen Lösungsmitteln oder weiteren die Komplexbil dung fördernden Mitteln.
<I>Beispiel:</I> 21,8 Teile des Farbstoffes aus diazotiertem 2-Amino-l-oxybenzol-4-sulfonsäuremethylamid und 1-(4'-Chlorphenyl)-3-methyl-5-pyrazolon und 23 Teile des Farbstoffes aus diazotiertem 3-Amino-4-oxy-1,1'-diphenylsulfon und 1-Ace- tylamino-7-oxynaphthalin, beide Farbstoffe in Form einer feuchten Paste (Filterkuchen) werden in 800 Teilen Wasser unter Zusatz von 8,0 Teilen Natriumhydroxyd gelöst.
Nun wird auf 80 erwärmt und mit 110 Teilen einer Kobaltsulfatlösung mit einem Kobalt-
EMI0002.0011
entsprechen, kobaltabgebende Mittel derart einwirken lässt, dass ein kobalthaltiger Azo- farbstoff entsteht, der je ein Molekül der zwei Ausgangsmonöazofarbstoffe an ein Kobalt atom komplex gebunden enthält.
Der neue kobalthaltige Farbstoff bildet ein dunkels Pulver, das sich in Wasser löst und Wolle aus neutralem oder schwach essigsau rem Bade in braunen Tönen färbt.
UNTERANSPRÜCHE 1. Verfahren gemäss Patentanspruch, da durch gekennzeichnet, dass man pro Molekül Behalt von 2,95% versetzt. Nach kurzem Er- wärmen auf 85 ist die Komplexbildung be endet. Durch Neutralisieren mit verdünnter Essigsäure und Natriumchloridzugabe wird der Farbstoff abgeschieden.
Additional patent to main patent No. 304040. Process for the production of an azo dye. It was found that this leads to a new, valuable, metal-containing azo dye
EMI0001.0007
correspond, allows cobalt-releasing agents to act in such a way that a cobalt-containing azo dye is formed which contains one molecule of each of the two starting monoazo dyes bonded to a cobalt atom in a complex.
The new cobalt-containing dye forms a dark powder that dissolves in water and dyes wool from a neutral or slightly acidic bath in brown shades.
The two monoazo dyes used as starting materials in the present process can be prepared by methods known per se by mixing diazotized 2-amino-l-oxybenzene-4-sulfonic acid methylamide with 1- (4'-chlorophenyl) -3-methyl-5-pyrazolone and dianotated 3-amino-4-oxy-1,1'-diphenylsulfone couples with 1-acetylamino-7-oxynaphthalene in an alkaline medium.
When performing the procedure, it is generally advisable to look at a total of approximately. 2 moles of monoazo dyestuff are obtained if a mixture of the two monoazo dyestuffs is
the following formulas and each containing about 1 mol of the two dyes used as starting materials contain an amount of a cobalt-releasing agent containing about one gram atom of cobalt and / or to carry out the metallization in a weakly acidic to alkaline medium.
For example, complex cobalt compounds of aliphatic o-oxycarboxylic acids or simple cobalt salts such as cobalt sulfate or cobalt acetate are particularly suitable as cobalt-releasing agents for carrying out the process.
The conversion of the dyes into the complex cobalt compounds takes place with advantage in the heat, open or under pressure, z. B. at the boiling point of the reaction mixture cal, optionally in the presence of appro-priate additives such. B. in the presence of salts of organic acids, bases, organic solvents or other agents promoting the complex formation.
<I> Example: </I> 21.8 parts of the dye from diazotized 2-amino-1-oxybenzene-4-sulfonic acid methylamide and 1- (4'-chlorophenyl) -3-methyl-5-pyrazolone and 23 parts of the dye from diazotized 3-amino-4-oxy-1,1'-diphenylsulfone and 1-acetylamino-7-oxynaphthalene, both dyes in the form of a moist paste (filter cake) are dissolved in 800 parts of water with the addition of 8.0 parts of sodium hydroxide solved.
Now is heated to 80 and 110 parts of a cobalt sulfate solution with a cobalt

correspond, allows cobalt-releasing agents to act in such a way that a cobalt-containing azo dye is formed which contains one molecule of each of the two starting monoazo dyes bound to a cobalt atom in a complex.
The new cobalt-containing dye forms a dark powder that dissolves in water and dyes wool from a neutral or slightly acidic bath in brown tones.
SUBClaims 1. A method according to claim, characterized in that a retention of 2.95% per molecule is added. After brief heating to 85, the complex formation is over. The dye is deposited by neutralizing with dilute acetic acid and adding sodium chloride.
