Verfahren zur Herstellung eines Monoazofarbstoffes <B>Es,</B> wurde gefunden, dass man zu einem wertvollen .llonoazofarbstoff gelangt, wenn man dianotiertes 4-Nitro-2-amino-l-oxy>bexizol. :n alkalischem Mittel mit 4-Methyl-2-acet.yl- ;11nino-1-oxybenzol vereinigt und den erhal.- i;
enen Farbstoff mit dem Farbstoff der Zu- samniensetzung
EMI0001.0015
mit chromabgebenden Mitteln derart behan delt, dass ein ehromhaltiger Farbstoff entsteht, (ler je ein Molekül der zwei Ausgangsmono- azofarlistoffe an ein Atom Chrom komplex gebunden enthält.
Der neue Farbstoff löst sich in Wasser lind färbt. Wolle aus schwach alkalischem, neutralem oder schwach essigsaurem Bade in braunen Tönen von guter Licht- und Wasch-' echtheit.
Die Dianotierung des 4-Nitro-2-amino-l- oxybenzols kann nach üblichen, an sich be kannten Methoden, z. B. mit Hilfe von Mine- i-a.lsä.lire, insbesondere Salzsäure und Na.- t riumnitrit, durchgeführt werden.
Die Kupplung wird in alkalischem, beispiels weise alkalicarbonat- oder alkalihydroxydalka- lischem Mittel, mit Vorteil unter Zusatz von l-naphthalixis-uilfonsaureni Natrium, vorge nommen.
Bei der Chroinierung empfiehlt es sich, auf ein Gemisch, bestehend aus etwa einem Mol des so erhaltenen Farbstoffes und etwa. einem Mol des Farbstoffes aus diaiotiertem 4-Nitro-2-amino-l-oxybenzol und 3,4-Dimethyl- l-oxybenzol eine etwa ein Grammatom Chrom enthaltende Menge eines chromabgebender Mittels zu verwenden und/oder die Chromie- rung in schwach saurem bis alkalischem Mit tel auszuführen.
Es sind zum Beispiel als ehromabgebende Mittel für die Durchführung des Verfahrens besonders gut geeignet kom plexe Chromverbindungen aliphatischer oder aromatiseher o-Oxycarbonsäuren, welche das Chrom in komplexer Bindung enthalten, und in alkalischem Medium beständig sind. Als Beispiele aromatischer Oxyearbonsäuren kön nen u. a. diejenigen der Benzolreihe wie die 4-, 5- oder 6-Methyl-l-oxybenzol-2-carbonsälix#e und vor allem die: Sal.ieylsällre selbst genannt werden.
Die Umwandlung der Farbstoffe in die komplexen Chromverbindungen geschieht mit Vorteil in der Wärme, offen oder unter Druck, z. B. bei Siedetemperatur des Reaktionsgemi- sehes, gegebenenfalls in Anwesenheit geeigne ter Zusätze, z.
B. in Anwesenheit von Salzen organischer Säuren, von Basen, organischen Lösungsmitteln oder weiteren die Komplex bildung fördernden. Mitteln. <I>Beispiel</I> 3,52 Teile Natriumsalz des Farbstoffes aus diazotiertem 4-Nitro-2-amino-l-oxybenzol und 4-Methyl-2-acetyl-amino-1-oxybenzol und 3,1 Teile Natriumsalz des Farbstoffes aus diazo- tiertem 4-Nitro-2-amino-l-oxybenzol und 3,4 Dimetliyl-l-oxybenzol, beide Farbstoffe in Form einer feuchten Paste (Filterkuchen),
werden in 300 Teilen Wasser verrührt und mit 25 Teilen einer Lösung von chromsalieyl- saurem Natrium-Kalium mit einem Chrom gehalt von 2,6<B>%</B> versetzt.
Das Ganze wird drei Stunden unter Rück flusskühlung gekocht. Nach dieser Zeit ist die Metallisierung beendet. Der gebildete Kom plex kann durch Ansäuern mit. Essigsäure oder durch Zugabe von Natriumehlorid ab geschieden werden.
Process for the Production of a Monoazo Dye It has been found that a valuable .lonoazo dye is obtained by using dianotated 4-nitro-2-amino-1-oxy> bexizole. : n alkaline agent combined with 4-methyl-2-acet.yl-; 11nino-1-oxybenzene and the obtained i;
enen dye with the dye of the composition
EMI0001.0015
Treated with chromium-releasing agents in such a way that a dye containing Ehrom is formed, (each containing one molecule of the two starting monoazofarlist substances bound to one atom of chromium in a complex.
The new dye dissolves in water and stains. Wool from weakly alkaline, neutral or weakly acetic acid baths in brown tones with good lightfastness and washfastness.
The Dianotierung of the 4-nitro-2-amino-l-oxybenzene can be according to customary methods known per se, for. B. with the help of minerals, especially hydrochloric acid and sodium nitrite.
The coupling is carried out in an alkaline, for example alkali carbonate or alkali hydroxide alkaline agent, advantageously with the addition of sodium l-naphthalixis-uilfonsaureni.
When chroining it is advisable to use a mixture consisting of about one mole of the dye thus obtained and about. one mole of the dyiotated 4-nitro-2-amino-1-oxybenzene and 3,4-dimethyl-1-oxybenzene an amount of a chromium donating agent containing about one gram atom of chromium and / or the chromizing in weakly acidic to alkaline agent.
Complex chromium compounds of aliphatic or aromatic o-oxycarboxylic acids, which contain the chromium in complex bonds and are stable in an alkaline medium, are, for example, particularly well suited as atom-releasing agents for carrying out the process. As examples of aromatic oxyearboxylic acids, u. a. those of the benzene series such as 4-, 5- or 6-methyl-1-oxybenzene-2-carbonsälix # e and above all the: Sal.ieylsallre themselves are called.
The conversion of the dyes into the complex chromium compounds takes place with advantage in the heat, open or under pressure, z. B. at the boiling point of the reaction mixture, optionally in the presence of suitable additives such.
B. in the presence of salts of organic acids, bases, organic solvents or other the complex formation promoting. Means. <I> Example </I> 3.52 parts of the sodium salt of the dye from diazotized 4-nitro-2-amino-1-oxybenzene and 4-methyl-2-acetyl-amino-1-oxybenzene and 3.1 parts of the sodium salt of the dye from diazotized 4-nitro-2-amino-l-oxybenzene and 3,4-dimethyl-l-oxybenzene, both dyes in the form of a moist paste (filter cake),
are stirred in 300 parts of water and mixed with 25 parts of a solution of chromsalieyl acid sodium-potassium with a chromium content of 2.6%.
The whole thing is boiled under reflux for three hours. After this time, the metallization is finished. The complex formed can be acidified with. Acetic acid or by adding sodium chloride.
