KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch Reduktion von I -Acetamido-2 · 4-dinitronaphthalin (Liebermann, Ann. 183, S. 274 und Meldola, Ber. 19, S. 2683) mit Eisen und verdünnter Essigsäure wird, wie festgestellt wurde, das 1-Monoacet-2· 4-triamidonaphthalin erhalten. Dasselbe kristallisiert aus der vom Eisen befreiten Reduktionslauge in schwach braunlich gefärbten Nadeln vom Schmelzpunkt 1890. Das i-Monoacet-2 · 4-triamidonaphthalin ist mäßig löslich in kaltem, leicht löslich in kochendem Alkohol; schwer löslich in Benzol und Ligroin und sehr leicht in Eisessig.By reducing I-acetamido-2 · 4-dinitronaphthalene (Liebermann, Ann. 183, p. 274 and Meldola, Ber. 19, p. 2683) with iron and dilute acetic acid, it has been found that the 1-monoacet-2 · 4-triamidonaphthalene obtained. The same is crystallized from the liquor freed from the iron reduction in slightly brownish colored needles of melting point 189 0th The i-monoacet-2 · 4-triamidonaphthalene is moderately soluble in cold, slightly soluble in boiling alcohol; Slightly soluble in benzene and ligroin and very easily in glacial acetic acid.
Es wurde nun weiter gefunden, daß das Monoacettriamidonaphthalin zur Darstellung eines gelben Schwefelfarbstoffs von klarer, goldgelber Nuance vorzüglich geeignet ist. Zu diesem Zwecke werden gleiche Mengen ι - Monoacet -2*4- triamidonaphthalin und Schwefel zusammengeschmolzen und die Temperatur etwa 5 Stunden auf höherer Temperatur, etwa i6o° gehalten. Aus der anfänglich dünnflüssigen, braunen Schmelze entweichen Schwefelwasserstoff und Wasserdämpfe. Ist die Schmelze zäh geworden und hat die Gasentwickelung beinahe aufgehört, so läßt man erkalten, worauf die spröde Schmelze sich leicht zu einem braungelben Pulver vermählen läßt. Der so erhaltene Farbstoff ist in kochender Schwefelnatriumlösung mit braungelber Farbe löslich. Die Lösung zeigt lebhafte gelbgrüne Fluoreszenz und färbt ungeheizte Baumwolle in klaren, goldgelben Tönen an. In kalter konzentrierter Schwefelsäure ist die Farbstoffschmelze unter Hinterlassung des nicht in Reaktion getretenen Schwefels mit braunroter Farbe löslich. Beim Verdünnen mit Wasser scheidet sich der Farbstoff in braunroten Flocken ab. Das Verhältnis von 1-Monoacet-2 · 4-triamidonaphthalin zu Schwefel kann auch anders gewählt werden.It has now been found that the monoacettriamidonaphthalene is used for representation of a yellow sulfur dye with a clear, golden-yellow shade is eminently suitable. For this purpose, equal amounts of ι - monoacet -2 * 4-triamidonaphthalene and Sulfur melted and the temperature about 5 hours at a higher temperature, held about 160 °. Escape from the initially thin, brown melt Hydrogen sulfide and water vapors. If the melt has become viscous and gas evolution has almost stopped, so it is allowed to cool, whereupon the brittle melt easily turns yellowish-brown Powder can be ground. The dye thus obtained is in a boiling sodium sulphide solution soluble with a brownish yellow color. The solution shows vivid yellow-green fluorescence and dyes unheated cotton in clear, golden yellow tones. The dye melts in cold concentrated sulfuric acid leaving the unreacted sulfur with a brownish red color soluble. When diluted with water, the dye separates out in brownish-red flakes. The ratio of 1-monoacet-2 · 4-triamidonaphthalene to sulfur can also be chosen differently will.
Der nach Patentschrift 82748 aus Nitroacet-a-naphtylamin bezw. dessen Reduktionsprodukt herstellbare gelbe Schwefelfarbstoff ist im Vergleich zu demjenigen dieser Erfindung von trüber, grünlichgelber Nuance und äußerst geringer Farbkraft.According to patent specification 82748 from nitroacet-a-naphtylamine respectively its reduction product is producible yellow sulfur dye as compared to that of this invention of cloudy, greenish-yellow nuance and extremely low color intensity.
