Description
Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie. Es wurde gefunden, dass man ein neues Zwischenprodukt, das primäre Kondensations produkt von einem Moleküle Cyanurchlorid mit einem lbioleküle Anilin, erhält, wenn man auf ein Moleküle Cyanurchlorid ein Moleküle Anilin einwirken lässt.
Diese .Kondensation wird zweckmässig durch Zusammenrühren der. Komponenten in einem geeigneten Verdünnungsmittel durch geführt. Es wurde gefunden, .dass als solches Wasser in überraseliender Weise sehr gut geeignet ist.
Das primäre Kondensationsprodukt aus einem Moleküle Cyanurchlorid mit einem Moleküle Anilin bildet ein kristallinisches Pulver, das aus Petroläther in farblosen Na deln vom Schmelzpunkt 135 bis 136 kristal lisiert. Es enthält noch zwei reaktionsfähige Chloratome und stellt ein wertvolles Aus gangsmaterial zur Herstellung von Farbstof fen dar.
<I>Beispiel:</I> Zu einer feinen, wässerigen l,\-ufschlem- mung von 18,5 Teilen Cyanurchlorid, die durch Eiszusatz bei 0 gehalten wird, lässt man unter Rühren eine Lösung von 9,3 Tei len Anilin in 400 Teilen Wasser und gleich zeitig eine verdünnte Sololösung fliessen, so dass die Reaktionsmasse fortwährend schwach kongosauer reagiert. Nachdem die Anilinlösung und im ganzen 5,3 Teile Soda zugesetzt worden sind, wird das gebildete primäre Kondensationsprodukt aus einem Moleküle Cyanurchlorid und einem Moleküle Anilin abfiltriert.
Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate product, the primary condensation product of a molecule of cyanuric chloride with a molecule of aniline, is obtained when a molecule of aniline is allowed to act on a molecule of cyanuric chloride.
This .Kondensation is expedient by stirring the. Components carried out in a suitable diluent. It has been found that, as such, water is very suitable in a surprising manner.
The primary condensation product of a molecule of cyanuric chloride with a molecule of aniline forms a crystalline powder that crystallizes from petroleum ether in colorless needles with a melting point of 135 to 136. It still contains two reactive chlorine atoms and is a valuable starting material for the production of dyes.
<I> Example: </I> To a fine, aqueous oil slurry of 18.5 parts of cyanuric chloride, which is kept at 0 by adding ice, a solution of 9.3 parts of aniline in 400 parts of water and at the same time a dilute solo solution flow so that the reaction mass continuously reacts weakly Congo acid. After the aniline solution and a total of 5.3 parts of soda have been added, the primary condensation product formed from one molecule of cyanuric chloride and one molecule of aniline is filtered off.
