Patentirt im Deutschen Reiche vom 30. Oktober 1894 ab.Patented in the German Empire on October 30, 1894.
Während sich Anilin und o-Toluidin mit Formaldehyd glatt und quantitativ zu Diamidodiphenylmethan bezw. Diamidoditolylmethan verbinden (Patentschriften Nr. 53937 und 55565), ist es bekanntlich bisher nicht gelungen, auf demselben Wege ein Diamidodinaphtylmethan zu erhalten. Beide Naphtylamine reagiren mit Formaldehyd in der Art, dafs sich 2 Mol.While aniline and o-toluidine with formaldehyde smoothly and quantitatively turn into diamidodiphenylmethane respectively Connect diamidoditolylmethane (patent specifications No. 53937 and 55565), it is known that it has not yet been possible to obtain a diamidodinaphthyl methane in the same way to obtain. Both naphthylamines react with formaldehyde in such a way that 2 mol.

Die so entstehenden Körper sind als Hydroacridine der Naphtalinreihe anzusprechen :the base with 1 mol. of the aldehyde with the escape of 1 mol. of water and 1 mol. of ammonia, the methane residue CH 2 always intervening in the ortho position to the amido group. The resulting bodies are to be addressed as hydroacridines of the naphthalene series:

bei welcher die Ortho - Stellung zur Amidogruppe durch die 5O3 H- Gruppe besetzt ist, liefert nun bei der Condensation mit Formaldehyd leicht und glatt die Ct1 aj-Diamido-a2 a2-dinaphtylmethan-ßj ßj-disulfosäure von der nebenstehenden Formel:in which the ortho position to the amido group is occupied by the 5O 3 H group, the condensation with formaldehyde easily and smoothly gives the Ct 1 aj-diamido-a 2 a 2- dinaphthylmethane-βj ßj-disulfonic acid of the formula opposite :

Beispiel: 45 kg aj-Naphtylamin-ßj-monosulfosäure werden in Form des Natronsalzes in 1000 1 siedenden Wassers gelöst, hierauf 7,5 kg Formaldehyd von 40 pCt. hinzugefügt und sofort mit etwa 30 kg Salzsäure (22 ° B.) angesäuert. Nach wenigen Minuten beginnt die Abscheidung der Diamidodinaphtylmethandisulfosäure und ist mit dem Erkalten der Flüssigkeit beendet. Die Säure wird abfiltrirt, mit Wasser gewaschen und getrocknet. Eine weitere Reinigung ist für technische Zwecke nicht erforderlich. Zum Zwecke der Darstellung analysenreiner Substanz löst man die Säure in einer verdünnten Lösung von Natriumacetat auf, filtrirt und fällt mit Salzsäure.Example: 45 kg of α-naphthylamine-β-monosulfonic acid are dissolved in 1000 liters of boiling water in the form of the sodium salt, then 7.5 kg Formaldehyde of 40 pCt. added and immediately acidified with about 30 kg of hydrochloric acid (22 ° B.). After a few minutes, the separation of the diamidodinaphthylmethanedisulfonic acid begins and is over when the liquid cools down. The acid is filtered off, washed with water and dried. One further purification is not necessary for technical purposes. For the purpose of illustration If the substance is analytically pure, the acid is dissolved in a dilute solution of sodium acetate up, filtered and precipitated with hydrochloric acid.
Die Diamidodinaphtylmethandisulfosäure krystallisirt in schwach gelblichen Nadeln mit ι Mol. Krystallwasser. Die Elementaranalyse bestätigt die Formel:The diamidodinaphthyl methanedisulfonic acid crystallizes in pale yellowish needles ι Mol. of crystalline water. The elemental analysis confirms the formula:
C21 C 21
N2 S2 O0 + H2 O. N 2 S 2 O 0 + H 2 O.
Ihre Salze sind farblos oder schwach gelblich, in Wasser gut löslich.Their salts are colorless or slightly yellowish and readily soluble in water.
Die Säure färbt sich langsam an der Luft, rasch unter der Einwirkung von Oxydationsmitteln blaugrün unter Bildung von Diamidonaphthydroldisulfosäure. - -The acid changes color slowly in the air, rapidly under the action of oxidizing agents blue-green with formation of diamidonaphthydrol disulfonic acid. - -
Sehr charakteristisch ist das Verhalten der Diamidodinaphtylmethandisulfosäure gegen salpetrige Säure. Versetzt man eine verdünnte wässerige Lösung ihres Alkalisalzes mit Natriumnitrit und säuert mit etwas Salzsäure an, so färbt sich die Lösung prachtvoll grün. Hierbei findet Diazotirung und gleichzeitige Oxydation zu Hydrol statt.The behavior of diamidodinaphtylmethanedisulphonic acid towards nitrous acid is very characteristic Acid. A dilute aqueous solution of its alkali salt is mixed with sodium nitrite and acidified with a little hydrochloric acid, the solution turns a splendid green. Here Diazotization and simultaneous oxidation to hydrol take place.
Die Diamidodinaphtylmethandisulfosäure ist unlöslich in kaltem Wasser, sehr schwer löslich in siedendem Wasser; in concentrirter Schwefelsäure löst sie sich mit grüner Fluorescenz. Diamidodinaphtylmethanedisulfonic acid is insoluble in cold water, very sparingly soluble in boiling water; in concentrated sulfuric acid it dissolves with green fluorescence.
Die neue Verbindung soll Verwendung finden zur Darstellung von Farbstoffen.The new compound is to be used for the representation of dyes.
