Im Gegensatz zu Dimethylanilin und Diäthylanilin condensiren sich die Dialkylderivate des o-Toluidins unter den üblichen Bedingungen bekanntlich nicht mit den aromatischen Aldehyden. Dagegen liefern die Monoalkyl-otoluidine mit derselben Leichtigkeit Körper der Triphenylmethanreihe, wie das Dimethylanilin.In contrast to dimethylaniline and diethylaniline, the dialkyl derivatives of It is well known that o-toluidine does not react with the aromatic aldehydes under the usual conditions. In contrast, the monoalkyl otoluidines deliver bodies of the triphenylmethane series with the same ease as dimethylaniline.
Sie unterscheiden sich also hierdurch wesentlich von den Monoalkylanilinen, welche letzteren unter ähnlichen Bedingungen vorwiegend Anhydroverbindungen liefern und sich demnach dem Anilin analog verhalten.In this way they differ significantly from the monoalkylanilines, the latter under similar conditions predominantly deliver anhydro compounds and accordingly behave analogously to aniline.
Während Dimethylanilin mit Benzaldehyd einen grünen Farbstoff, das Malachitgrün, liefert, bringt das Monomethyl-o-toluidin mit Benzaldehyd und darauf folgender Oxydation einen grünblauen Farbstoff hervor, der allerdings wegen seiner stumpfen Nuance nur untergeordnetes Interesse beansprucht.While dimethylaniline and benzaldehyde create a green dye, malachite green, supplies, brings the monomethyl-o-toluidine with benzaldehyde and subsequent oxidation a green-blue dye emerges, but only because of its dull shade subordinate interest claimed.
Dagegen hat sich herausgestellt, dafs bei Verwendung des Dichlorbenzaldehydes. welcher von R. Gnehm, Ber. XVII, S. 752, zuerst beschrieben worden ist, und der auf verschiedenem Wege, ζ. B. nach der in der Patentschrift Nr. 32238 beschriebenen Methode aus Dichlorbenzylidenchlorid, dargestellt werden kann, sehr werthvolle blaue basische Farbstoffe von grofser Reinheit erhalten werden. Dieselben färben Wolle und Seide, sowie mit Tannin und Brechweinstein gebeizte Baumwolle blau, in der Nuance zwischen , dem blauesten Grün und dem bis jetzt bekannten grünsten Blau.In contrast, it has been found that when using dichlorobenzaldehyde. which by R. Gnehm, Ber. XVII, p. 752, and that on various Ways, ζ. B. by the method described in patent specification No. 32238 from dichlorobenzylidene chloride, very valuable blue basic dyes of great purity can be obtained. The same dye wool and silk, as well as cotton stained with tannin and tartarine blue, in the shade between, the bluest green and the greenest blue known up to now.
A. Condensation.A. Condensation.
Die Darstellung des symmetrischen Dimethyldiamido - ο - ditolyldichlorphenylmethans kann beispielsweise in der Art ausgeführt werden, dafs 60 Theile reines Monomethyl-o-toluidin mit 44 Theilen Dichlorbenzaldehyd, 60 Theilen Alkohol und 25 Theilen Schwefelsäure in einem mit Rührer versehenen und ausgebleiten Kessel während 24 Stunden im Wasserbade erwärmt werden.The representation of the symmetrical Dimethyldiamido - ο - ditolyldichlorphenylmethans can for example, be carried out in such a way that 60 parts of pure monomethyl-o-toluidine with 44 parts dichlorobenzaldehyde, 60 parts alcohol and 25 parts sulfuric acid in a kettle equipped with a stirrer and blown out in a water bath for 24 hours be heated.
Man übersättigt hierauf mit Natronlauge, treibt die eventuell unangegriffenen OeIe mit Wasserdampf ab und kocht die zurückbleibende Leukobase wiederholt mit Wasser aus.One then oversaturated with caustic soda, drives the possibly unaffected oils with it Steam and the remaining leuco base repeatedly boiled with water.
In analoger Weise erhält man das symmetrische Diäthyldiamido - ο - ditolyldichlorphenylmethan, wenn man statt Monomethyl-o-toluidin die entsprechende Menge Monoäthyl-o-toluidin anwendet.The symmetrical diethyldiamido - ο - ditolyldichlorophenylmethane is obtained in an analogous manner, if instead of monomethyl-o-toluidine the corresponding amount of monoethyl-o-toluidine applies.
An Stelle der Schwefelsäure kann zur Condensation Salzsäure oder Chlorzink verwendet werden.Instead of sulfuric acid, hydrochloric acid or zinc chloride can be used for condensation will.
Die nach diesem Verfahren erhaltenen Leukobasen sind in reinem Zustande farblose krystallinische Verbindungen, die sich leicht in Aether, Benzol, warmem Alkohol und Mineralsäuren auflösen, in Wasser und Alkalien dagegen unlöslich sind.The leuco bases obtained by this process are colorless in their pure state Crystalline compounds that are easily broken down into ether, benzene, warm alcohol, and mineral acids dissolve, but are insoluble in water and alkalis.
B. Oxydation.B. Oxidation.
Zur Ueberführung der Leukobasen in die Farbstoffe werden dieselben in verdünnten Mineralsä'uren gelöst und mit geeigneten Oxydationsmitteln, z. B. mit Superoxyden, oxydirt.To transfer the leuco bases to the The same dyes are dissolved in dilute mineral acids and treated with suitable oxidizing agents, z. B. with superoxides, oxidized.
Es werden z. B. 30 Theile symmetrisches Dimethyldiamido - ο - ditolyldichlorphenylmethan in 40 Theilen Salzsäure und 1500 Theilen Wasser gelöst und zu dieser Lösung die berechnete Menge in Wasser aufgeschlemmtesThere are z. B. 30 parts of symmetrical dimethyldiamido - ο - ditolyldichlorophenylmethane dissolved in 40 parts hydrochloric acid and 1500 parts water, and the calculated solution for this solution Amount of dissolved in water
