Condensirt man Amido-α- bezw. -ß-oxynaphtoesäure mit 1 · 3 -Dinitro - 4 - chlorbenzol, so erhält man Dinitrophenylamidooxynaphtoesäuren, welche vorgebeizte Wolle braun färben. Verschmilzt man diese Zwischenproducte mit Schwefel und Schwefelnatrium oder ähnlich wirkenden Substanzen, so erhält man Farbstoffe, welche die Eigenschaft besitzen, ungeheizte Baumwolle bröunlichroth anzufärben. Durch Nachbehandeln dieser Färbungen mit Kupfer- bezw. Chromsalzen wird der Ton mehr oder minder nach braun hin verändert. Man kann die Nuancen und Stärke der Farbstoffe durch Veränderungen in den Mengenverhältnissen der Schmelzingredienzien, der Schmelztemperatur und der Zeit des Erhitzens abändern. ;If one condenses amido-α- resp. -ß-oxynaphtoic acid with 1 · 3-dinitro - 4 - chlorobenzene, one obtains dinitrophenylamidooxynaphthoic acids, which dye pre-stained wool brown. If one fuses these intermediate products with Sulfur and sodium sulphide or substances with a similar effect, this is how dyes are obtained, which have the property of staining unheated cotton a brownish red color. By treating these colorations with copper or copper. With chromium salts, the tone is more or less changed to brown. You can change the nuances and strength of the dyes by changing the proportions the melting ingredients, the melting temperature and the time of heating. ;
203 kg Ämido-a-oxynaphtoesäure werden mit einer Lösung von 53 kg Soda in 1000 1 Wasser in das Natriumsalz übergeführt und bei Gegenwart von Salzsäure bindenden Mitteln, wie Natriumacetat oder Soda, mit einer alkoholischen Lösung von 202 kg 1 · 3-Dinitro-4-chlorbenzol einige Stunden am Rückflufskühler erhitzt. Das zum gröfsten Theil ausfallende Condensationsproduct — Dinitrophenylamidooxynaphtoesäure — wird in das Natriumsalz übergeführt und mit Schwefel und Schwefelnatrium verschmolzen. Zu diesem Zwecke werden 25 kg des Condensationsproductes mit einer wässrigen Lösung von 100 kg krystallisirtem Schwefelnatrium und 40 kg Schwefel in einern eisernen Kessel verrührt und allmählich auf ca. 140 bis i6o° oder höher erhitzt, bis die Schmelze fest geworden ist.203 kg of amido-a-oxynaphthoic acid are mixed with a solution of 53 kg of soda in 1000 l Water converted into the sodium salt and in the presence of hydrochloric acid binding agents, like sodium acetate or soda, with an alcoholic solution of 202 kg of 1 x 3-dinitro-4-chlorobenzene heated for a few hours on the reflux condenser. That which for the most part fails Condensation product - dinitrophenylamidooxynaphthoic acid - is converted into the sodium salt transferred and fused with sulfur and sulfur sodium. Be for this purpose 25 kg of the condensation product with an aqueous solution of 100 kg crystallized Sodium sulfur and 40 kg of sulfur are stirred in an iron kettle and gradually heated to approx. 140 to 160 ° or higher, until the melt has solidified.
Das so erhaltene Product kann direct zum Färben von Baumwolle verwendet werden und liefert braunrothe Färbungen. Der Farbstoff aus a - Oxynaphtoesäure . löst sich in Wasser röthlichbraun, in Schwefelalkalilösung olivbraun, in concentrirter Schwefelsäure olivgrün. Er färbt Baumwolle rothbraun, die Färbung wird beim Nachkupfern oder Nachchromiren braunstichiger. The product obtained in this way can be used directly for dyeing cotton and provides brown-red dyeings. The dye from a - oxynaphtoic acid. Dissolves reddish-brown in water, olive-brown in alkali-sulfur solution, olive-green in concentrated sulfuric acid. It dyes cotton a reddish-brown; the color becomes more brownish with copper-plating or chrome-plating.
Der Farbstoff aus ß-Oxynaphtoesäure löst sich in Wasser und in wässrigem Schwefelnatrium intensiv gelbbraun, in concentrirter Schwefelsäure violettbraun. Er färbt Baumwolle röthlich graubraun, die Färbung wird beim Nachkupfern oder Chromiren brauner.The dye from ß-oxynaphtoic acid dissolves in water and in aqueous sodium sulphide intense yellow-brown, violet-brown in concentrated sulfuric acid. It dyes cotton reddish gray-brown, the color becomes browner with copper or chrome-plating.
