Description
Verfahren zur Herstellung in Wasser schwer löslicher Monoazofarbstoffe Gegenstand der Erfindung ist ein Verfahren zur Herstellung in Wasser schwer löslicher Monoazofarb- stoffe der Formel
EMI0001.0007
worin x Halogen, z Halogen oder Trifluormethyl, y Wasserstoff oder Methyl und n und m ganze Zahlen von 1 bis 4 bedeuten.
Das erfindungsgemässe Verfahren ist dadurch ge kennzeichnet, dass man 1 Mol eines 1-Diazo-4-nitro- 2,6 - dihalogen - benzols bzw. -2 - halogen-6-trifluor- methyl-benzols mit 1 Mol eines tertiären Amins der Formel
EMI0001.0019
worin y Wasserstoff oder Methyl und n und m ganze Zahlen von 1 bis 4 bedeuten, kuppelt.
Die neuen Farbstoffe ziehen auf Celluloseester- fasern, synthetische Polyamidfasern, Polyolefinfasern, Polyvinylfasern und Polyacrylnitrilfasern in braun stichig gelben Tönen auf. Gegenüber ähnlichen, be reits bekannten Farbstoffen besitzen sie in erster Linie Vorteile beim Färben von Polyesterfasern, z. B. von Polyäthylenglykolterephthalatfasern (z.
B. Tery- lene , Dacron , Trevira , Tergal , Diolen , Terital , Teron ; eingetragene Marken) und 1,4- Dimethylenphenylglykolterephthalatfasern (z. B. Ko- del ; eingetragene Marke), ferner von Triacetatkunst- seile (z. B. Arnel , Tricel ; eingetragene Marken).
Es werden auf diesen Fasern braunstichig gelbe Farb töne erhalten, die sich durch sehr gute Licht-, Wasch-, Schweiss-, Rauchgas-, Sublimier-, Plissier- und Thermofixierechtheit auszeichnen. Ausserdem reser vieren die neuen Farbstoffe begleitendes Woll-, Baum- woll- und Viskosematerial recht gut, und diese Re serven lassen sich durch eine Nachbehandlung mit reduzierenden Mitteln, z. B. Natriumhydrosulfit, noch verbessern.
Einer der grossen Vorteile der neuen Farbstoffe liegt darin, dass sie sich mit geeigneten Rot- und Blaumarken auf Polyesterfasern zu licht echten Beige-, Braun-, Grau-, Oliv- und Marineblau- tönen kombinieren lassen. Die bis jetzt bekannten gelben Polyesterfarbstoffe waren entweder farb- schwach (Nitrofarbstoffe) oder in Kombination zu wenig licht- und sublimierecht.
Die neuen Farbstoffe sind auch zum Färben von Lacken, Ölen, Kunstharzen oder von künstlichen Fasern in der Masse geeignet.
Die Kupplung der Diazoverbindung mit der Azo- komponente erfolgt vorzugsweise in saurem Medium, gegebenenfalls in Gegenwart säurebindender Mittel. Die ausgeschiedenen Monoazofarbstoffe werden ab filtriert und gewaschen.
Im folgenden Beispiel sind unter Teilen Gewichts teile zu verstehen. Die Temperaturen sind in Celsius- graden angegeben, und die Schmelzpunkte sind un- korrigiert.
<I>Beispiel</I> 20,7 Teile 1-Amino-2,6-dichlor-4-nitrobenzol werden in eine in üblicher Weise hergestellte Lösung von 6,9 Teilen Natriumnitrit in 150 Teilen konzen trierter Schwefelsäure bei 15-20 eingetragen. Nach beendigter Diazotierung lässt man die entstandene Lö sung langsam zu einer Lösung von 22 Teilen N- Cyanäthyl-N-äthylaminobenzol in 200 Teilen Eisessig tropfen, wobei man durch Eintragen von Eis die Temperatur auf 0 hält.
Der abgeschiedene Farbstoff wird abfiltriert, mit kaltem Wasser sorgfältig neutral gewaschen und ge trocknet. Man erhält ein braun gefärbtes Pulver vom Schmelzpunkt 144-146 .
Ähnliche Farbstoffe werden erhalten, wenn man die gleiche Diazoverbindung mit N-Cyanäthyl-N- methylaminobenzol, N-Cyanäthyl-N-propylaminoben- zol oder N-Cyanäthyl-N-butylaminobenzol kuppelt.
Process for the preparation of monoazo dyes that are sparingly soluble in water The invention relates to a process for the preparation of monoazo dyes of the formula which are sparingly soluble in water
EMI0001.0007
where x is halogen, z is halogen or trifluoromethyl, y is hydrogen or methyl and n and m are integers from 1 to 4.
The process according to the invention is characterized in that 1 mol of a 1-diazo-4-nitro-2,6-dihalo-benzene or -2-halogen-6-trifluoromethyl-benzene is mixed with 1 mol of a tertiary amine of the formula
EMI0001.0019
where y is hydrogen or methyl and n and m are integers from 1 to 4, couples.
The new dyes are absorbed onto cellulose ester fibers, synthetic polyamide fibers, polyolefin fibers, polyvinyl fibers and polyacrylonitrile fibers in shades of brown, pale yellow. Compared to similar, already known dyes, they primarily have advantages when dyeing polyester fibers, eg. B. of polyethylene glycol terephthalate fibers (e.g.
B. Terelene, Dacron, Trevira, Tergal, Diolen, Terital, Teron; registered trademarks) and 1,4-dimethylene phenylglycol terephthalate fibers (e.g. Koel; registered trademark), furthermore from triacetate synthetic ropes (e.g. Arnel, Tricel; registered trademarks).
Brownish yellow shades are obtained on these fibers, which are characterized by very good fastness to light, washing, perspiration, smoke gas, sublimation, pleating and thermosetting. In addition, the new dyes reserve the accompanying wool, cotton and viscose material quite well, and these reserves can be post-treated with reducing agents, e.g. B. sodium hydrosulfite, still improve.
One of the great advantages of the new dyes is that they can be combined with suitable red and blue brands on polyester fibers to create light beige, brown, gray, olive and navy blue tones. The yellow polyester dyes known up to now were either weak in color (nitro dyes) or, in combination, too little lightfast and sublimation fast.
The new dyes are also suitable for coloring paints, oils, synthetic resins or artificial fibers in bulk.
The coupling of the diazo compound with the azo component is preferably carried out in an acidic medium, optionally in the presence of acid-binding agents. The precipitated monoazo dyes are filtered off and washed.
In the following example, parts are parts by weight. The temperatures are given in degrees Celsius and the melting points are uncorrected.
<I> Example </I> 20.7 parts of 1-amino-2,6-dichloro-4-nitrobenzene are introduced into a conventionally prepared solution of 6.9 parts of sodium nitrite in 150 parts of concentrated sulfuric acid at 15-20 . When the diazotization is complete, the resulting solution is slowly added dropwise to a solution of 22 parts of N-cyanoethyl-N-ethylaminobenzene in 200 parts of glacial acetic acid, the temperature being kept at 0 by adding ice.
The deposited dye is filtered off, carefully washed neutral with cold water and dried. A brown colored powder with a melting point of 144-146 is obtained.
Similar dyes are obtained if the same diazo compound is coupled with N-cyanoethyl-N-methylaminobenzene, N-cyanoethyl-N-propylaminobenzene or N-cyanoethyl-N-butylaminobenzene.
