Description
Verfahren zur Darstellung eines Triarylmethanfarbstoffes. In Triarylmethanfarbstoffen, die sich von tertiären Aminen ableiten, nehmen Farb- stärke und Verwandtschaft zur Faser mit steigender Molekulargrösse der angewandten tertiären Amine zu und auch der Farbton wird hierdurch beeinflusst. Mit der Vergrö sserung des Molekulargewichtes nimmt aber die Löslichkeit ab, und dem gesteigerten Ziehvermögen entspricht eine Abnahme des Egalisiervermögens.
So ist zum Beispiel der Farbstoff aus Benzaldehyddisulfosäure und Äthylbenzyl- anilin wesentlich farbstärker als der entspre chende Farbstoff aus Diäthylanilin, aber er egalisiert erheblich schlechter, so dass er zum Nuancieren im kochenden Bade in der Praxis kaum noch verwendet wird.
Sucht man zum Beispiel durch Einführung höherer Alkylreste in die zum Aufbau basischer Farbstoffe be nutzten tertiären Amine, meist Dimethyl- oder Diäthylarylamine, den Farbton der Färbungen nach der langwelligen Seite des Spektrums zu verschieben, so werden nicht nur die Farbstoffe ungenügend löslich, son dern auch die Leukoverbindungen sind für eine normale Weiterverarbeitung zu schwer löslich.
Wie gefunden wurde, gelingt es, unter Vermeidung der erwähnten Nachteile, in Triarylmethanfarbstoffe Reste von höhere Alkyle enthaltenden tertiären Aminen ein zuführen, wenn man sich solcher tertiärer Arylamine bedient, in denen neben einer Butyl- oder andern höheren Alkylgruppe noch eine Oxalkylgruppe an das Stickstoff atom gebunden ist. Solche Oxalkyl-Alkyl- Arylamine erhält man, wenn man sekundäre Alkylarylamine mit Alkylenoxyden im ge schlossenen Gefäss auf Temperaturen zwi schen 100 und 180 erhitzt.
Für die Darstellung der Farbstoffe gelten im übrigen die üblichen Methoden. Die hin reichend löslichen Leukoverbindungen ent stehen ohne unerwünschte Nebenreaktionen in sehr guter Ausbeute. Ihre Oxydation ver läuft trotz der Anwesenheit von alkoholischen Oxygruppen normal.
Die neuen Farbstoffe zeichnen sich durch eine sehr gute Löslichkeit, eine im Vergleich zur geringen Zunahme des Molekulargewichtes auffallend erhöhte Farbstärke und sehr klare Töne der mit ihnen hergestellten Färbungen, besonders auch bei künstlichem Licht, aus.
Nach vorliegender Erfindung erhält man einen die tierische Faser oder die gebeizte pflanzliche Faser klar blauviolett färbenden Farbstoff, dessen Base der Konstitution ent spricht:
EMI0002.0003
indem man 4.4'-Di-(butyl-oxyäthyl-amino)- benzhydrol mit Butyl-oxyäthyl-aminobenzol kondensiert und die gebildete Leukoverbin= dung zum Farbstoff oxydiert.
<I>Beispiel:</I> Man kondensiert in üblicher Weise 11 Teile Formaldehyd 30 o/oig bei Gegen wart einer katalytischen Menge einer schwa chen organischen Säure mit 38,5 Teilen Bu- tyl-oxyäthyl-aminobenzol zum 4.4'-Di-(biityl- oxyäthyl-amino)-diphenylmethan und oxydiert dieses in üblicher Weise, z.
B. mit Bleisuper oxyd und Schwefelsäure, zum entsprechenden Benzhydrol. Dieses kondensiert man mit 15 Teilen Butyl-oxyäthyl-aminobenzol etwa nach Möhlau und Bucherer, Farbenchemisches Praktikum, I. Aufl., 1908, S. 183 ff., zur Leukobase und oxydiert diese. Man erhält in sehr guter Ausbeute einen gut löslichen Farb- stoff, der wesentlich blauer und klarer ist als die bekannten Methylviolettmarken. Bei künstlichem Licht schlägt der Farbton bei weitem nicht so ins stumpfe Rötliche um, wie bei den bekannten analogen Farbstoffen.
Process for the preparation of a triarylmethane dye. In triarylmethane dyes, which are derived from tertiary amines, the color strength and relationship to the fiber increase with the increasing molecular size of the tertiary amines used, and the color tone is also influenced by this. As the molecular weight increases, however, the solubility decreases, and the increased drawability corresponds to a decrease in the leveling capacity.
For example, the dye made from benzaldehyde disulfonic acid and ethylbenzyl aniline is much stronger in color than the corresponding dye made from diethyl aniline, but it levels out considerably worse, so that it is rarely used in practice for shading in the boiling bath.
If one tries, for example, by introducing higher alkyl radicals into the tertiary amines used to build up basic dyes, usually dimethyl or diethylarylamines, to shift the hue of the dyeings to the long-wave side of the spectrum, not only are the dyes insufficiently soluble, but also the leuco compounds are too sparingly soluble for normal processing.
As has been found, while avoiding the disadvantages mentioned, it is possible to introduce residues of higher alkyl-containing tertiary amines into triarylmethane dyes if one uses such tertiary arylamines in which, in addition to a butyl or other higher alkyl group, an oxalkyl group is attached to the nitrogen atom is bound. Such oxalkyl-alkyl-arylamines are obtained if secondary alkylarylamines with alkylene oxides are heated to temperatures between 100 and 180 in a closed vessel.
The usual methods apply to the representation of the dyes. The sufficiently soluble leuco compounds are produced in very good yield without undesired side reactions. Their oxidation proceeds normally despite the presence of alcoholic oxy groups.
The new dyes are distinguished by very good solubility, a noticeably increased color strength compared to the slight increase in molecular weight, and very clear tones of the colorations produced with them, especially with artificial light.
According to the present invention, the animal fiber or the stained vegetable fiber is obtained which has a clear blue-violet coloring and the base of which corresponds to the constitution:
EMI0002.0003
by condensing 4,4'-di- (butyl-oxyethyl-amino) -benzhydrol with butyl-oxyethyl-aminobenzene and oxidizing the leuco compound formed to the dye.
<I> Example: </I> 11 parts of 30% formaldehyde are condensed in the usual way in the presence of a catalytic amount of a weak organic acid with 38.5 parts of butyl-oxyethyl-aminobenzene to give 4.4'-di- (Biityl- oxyäthyl-amino) -diphenylmethane and oxidizes this in the usual way, eg.
B. with lead super oxide and sulfuric acid, to the corresponding benzhydrol. This is condensed with 15 parts of butyl-oxyethyl-aminobenzene according to Möhlau and Bucherer, Farbenchemisches Praktikum, 1st edition, 1908, p. 183 ff., To give the leuco base and oxidize it. A readily soluble dye is obtained in very good yield, which is significantly bluer and clearer than the known methyl violet brands. With artificial light, the hue does not change into the dull reddish by far as with the known analogous dyes.
