Aus den durch Combination von Diazoverbindungen mit der Diamidonaphtalin-α-disulfosäure erhaltenen Farbstoffen gelingt es, unter gewissen Bedingungen eine Amidogruppe abzuspalten und durch die Hydroxylgruppe zu ersetzen. Bei dieser Umwandlung erhält man Farbstoffe, welche identisch sind mit den aus Diazoverbindungen und der Amidonaphtoldisulfosäure H in alkalischer Lösung gebildeten Farbstoffen. Die Amidonaphtoldisulfosäure H, welche aus Diamidonaphtalin-α-disulfosäure durch Erhitzen mit Mineralsäuren entsteht, ist identisch mit der Säure, die aus der Koctischen Naphtylamintfisulfosäure in der Alkalischmelze gebildet wird. Daher sind die Farbstoffe, welche nach dem vorliegenden Verfahren erhalten werden, identisch mit den Farbstoffen des Patentes Nr. 62368. Als geeignete Mittel zur Ueberführung kommen verdünnte Mineralsäuren und wässerige kaustische Alkalien zur Verwendung.From the dyes obtained by combining diazo compounds with diamidonaphthalene-α-disulfonic acid, it is possible, under certain conditions, to split off an amido group and replace it with the hydroxyl group. In this conversion, dyes are obtained which are identical to the dyes formed from diazo compounds and amidonaphthol disulfonic acid H in an alkaline solution. The amidonaphthol disulfonic acid H, which is formed from diamidonaphthalene-α-disulfonic acid by heating with mineral acids, is identical to the acid which is formed from the octal naphthylamine disulfonic acid in the alkali melt. Therefore, the dyes obtained by the present process are identical to the dyes of Patent No. 62368. Dilute mineral acids and aqueous caustic alkalis are used as suitable conversion agents.
Beispiel: 46,5 kg des aus 1 Aequivalent Diazobenzol und 1 Aequivalent Diamidonaphtalin-a-disulfosäure erhaltenen braunen Farbstoffes werden in 1000 1 Wasser gelöst und 100 kg Salzsäure (210B.) hinzugegeben. Man erwärmt zunächst auf 6o° C. Bei dieser Temperatur beginnt die violette Farbe der Flüssigkeit allmälig in roth überzugehen. Zum Schlufs erwärmt man kurze Zeit zum Kochen. Nach dem Erkalten wird der ausgeschiedene Farbstoff abfiltrirt. In der Lösung findet sich ι Aequivalent Chlorammonium; oderExample: 46.5 kg of the 1 equivalent of diazobenzene and 1 equivalent Diamidonaphtalin-a-disulfonic acid resulting brown dye are dissolved in 1000 1 of water and add 100 kg of hydrochloric acid (21 0 B.). It is first heated to 60 ° C. At this temperature the violet color of the liquid begins to gradually turn red. At the end, warm up to boil for a short time. After cooling, the precipitated dye is filtered off. In the solution there is an equivalent of chlorammonium; or
62 kg des aus 1 Aequivalent ß-Naphtylaminß-sulfosäure (Brönner) und 1. Aequivalent Diamidonaphtalin - α - disulfosäure erhaltenen Farbstoffes werden mit 300 1 Wasser und 120 kg Natronhydrat so lange zum Kochen erhitzt, bis die Entwickelung von Ammoniak aufgehört hat. Durch Neutralisiren wird der Farbstoff abgeschieden.62 kg of 1 equivalent of ß-naphthylamineß-sulfonic acid (Brönner) and the 1st equivalent of diamidonaphthalene - α - disulfonic acid The dye is boiled with 300 l of water and 120 kg of sodium hydrate heated until the development of ammonia has ceased. By neutralizing the Dye deposited.
In analoger Weise werden die Combinationen behandelt, welche aus Diazotoluol, Diazoxylol, Diazoazobenzol- und Toluolsulfosäuren, Diazobenzoesäure, Diazonaphtalin, Diazoazobenzol, Diazonaphtalinsulfosäure u. s. f. erhalten werden.The combinations which consist of diazotoluene, diazoxylol, Diazoazobenzene and toluene sulfonic acids, diazobenzoic acid, diazonaphthalene, diazoazobenzene, Diazonaphthalene sulfonic acid and the like.
Die sämmtlichen Farbstoffe färben Wolle in saurem Bade roth bis blauroth. Sie besitzen ein gutes Egalisirungsvermögen; sie zeigen die für alkalisch combinirte Amidonaphtolsulfosäurefarbstoffe charakteristische Eigenschaft der Diazotirbarkeit. Hieraus, sowie aus den Nuancen und den Reductionsproducten hat sich die Identität der Farbstoffe mit den entsprechenden Azoderivaten der Amidonaphtoldisulfosäure H ergeben.All the dyes dye wool in an acidic bath red to bluish-red. You own good leveling power; they show the amidonaphthol sulfonic acid dyes combined for alkaline characteristic property of diazotization. From this, as well as from the nuances and the reduction products have the identity of the dyes with the corresponding Azo derivatives of amidonaphthol disulfonic acid H give.
