Verfahren zur Darstellung von Kondensationsprodukten der Gallocyanine mit Aminen. sowie von entkarboxylierten Derivaten dieser vom gewöhnlichen Gallocvanin abgeleiteten
Kondensationsprodukte und von Sulfoderivaten dieser letzteren.
In der deutschen Patentschrift Nr. 192529 ist angegeben, dass bei der Kondensation von Galloeyanin mit Aminen nur etwa die Hälfte der erzielbaren Ausbeute erhalten wird, weil die Hälfte des angewandten Gallocyaninfarbstoffes durch den frei werdenden Wasserstoff reduziert wird. Diesem Übelstande kann man nach dem Verfahren der obigen deutschen Patentschrift dadurch abhelfen, dass man die Kondensation bei Gegenwart oxydierend wirkender Nitrokohlenwasserstoffo ausführt.
Es wurde jetzt gefunden, dass man dieses Ziel in glatterer und vorteilhafterer Weise erreicht, wenn man die Oxydation statt durch Nitrokohlenwasserstoffe durch gasförmigen Sauerstoff bewirkt, indem man bei der Kondensation des GaHocyanins mit dem Amin

Es wurde ferner gefunden, dass diese Amidoarylderivate des entkarboxylierten Gallocyanins bei der Sulfierung Farbstoffe liefern, die sich von den nach den deutschen Patentschriften Nr. 55942 und 57453 erhaltenen Farbstoffen durch eine aussergewöhnliche Klarheit und grössere Chlorechtheit auszeichnen. Wahrscheinlich liegen in den in den deutschen Patentschriften Nr. 55942 und 57453 benutzten Amidoarytverbindungen isomere Arylido oder Gemische verschiedener Arylide vor.

Anstelle des Anilidoproduktes lassen sich im obigen Beispiele auch die Analogen und Homologen, z. H. das Toluido-, das Chloranilidoprodukt, verwenden. Die hieraus erhältlichen Farbstoffe zeigen ein ähnliches Verhalten.
PATENT-ANSPRÜCHE :
1. Verfahren zur Darstellung von Kondensationsprodukten der Gallocyanine mit Aminen, dadurch gekennzeichnet, dass man die Kondensation bei Gegenwart von gasförmigem Sauerstoff, in An-oder Abwesenheit von Sauerstoffüberträgern bewirkt.

Process for the preparation of condensation products of gallocyanines with amines. as well as decarboxylated derivatives of those derived from common galvanic vanin
Condensation products and sulfoderivatives of the latter.
In the German patent specification No. 192529 it is stated that only about half of the achievable yield is obtained in the condensation of galloeyanin with amines, because half of the gallocyanin dye used is reduced by the hydrogen released. This inconvenience can be remedied by the process of the above German patent specification by carrying out the condensation in the presence of oxidizing nitrohydrocarbons.
It has now been found that this aim can be achieved in a smoother and more advantageous manner if the oxidation is effected by gaseous oxygen instead of by nitrohydrocarbons, by condensing the gasocyanine with the amine

gallocyanin be converted.
It has also been found that these amidoaryl derivatives of decarboxylated gallocyanine give dyes during sulfonation which are distinguished from the dyes obtained according to German Patent Nos. 55942 and 57453 by an exceptional clarity and greater resistance to chlorine. The amidoaryt compounds used in German Patent Nos. 55942 and 57453 probably contain isomeric arylido or mixtures of different arylides.

A vigorous stream of air is continuously introduced at normal temperature, the anilidogallocyanin still containing the carboxyl group being formed in excellent yield and purity, which is either isolated directly from the reaction mass. or by gradually heating the reaction mass to 110 in the decarboxylated anilidover-

and yield achieved, which is particularly evident in the dye obtainable by sulfation.
B e i s i e l II. 50 kg of the decarbonated condensation product obtained according to the preceding example from gahocyanine and aniline become smokier in 200 parts

gradually heated to 30-40 "with stirring until a sample is dissolved in soda. The reaction mass is then poured into water, the sulfonic acid which has separated out is filtered off and converted into the ammonium salt.
The dye stains chromed wool in beautiful, genuine greenish blue tones and, with the aid of chrome stains, provides very valuable green-blue nuances, especially in cotton printing.

Instead of the anilido product, the analogs and homologues, e.g. H. Use the toluido, the chloroanilido product. The dyes obtainable therefrom show a similar behavior.
