Das Verfahren wird durch folgendes Beispiel erläutert:The procedure is illustrated by the following example:
24,6 kg Acetdiamidophenolsulfosäure werden mit 12 kg Soda in 250 1 Wasser gelöst; in die auf o° abgekühlte, mit 40 kg Salzsäure 20° Be. versetzte Lösung werden allmählich 6,9 kg Nitrit eingetragen. Hierbei bildet sich die gelbgefärbte Diazoverbindung, die sich zum Teil in kristallinischer Form ausscheidet. Man läßt sie in die Lösung von 36 kg 1-8'3'6-Amidonaphtoldisulfosäure und 35 kg Soda einlaufen und fällt den gebildeten Farbstoff nach etwa 12 Stunden mit Salz aus.24.6 kg acetdiamidophenolsulfonic acid are dissolved with 12 kg soda in 250 l water; in the cooled to 0 °, with 40 kg hydrochloric acid 20 ° Be. mixed solution are gradually introduced 6.9 kg of nitrite. The yellow colored diazo compound is formed, some of which is precipitated in crystalline form. They are allowed to run into the solution of 36 kg of 1-8'3'6-amidonaphthol disulfonic acid and 35 kg of soda and the dye formed is precipitated with salt after about 12 hours.
Er färbt Wolle direkt in saurem Bade violett. Die Farbe verwandelt sich bei der Nachbehandlung mit Bichromat in Blauschwarz. Diese Färbung ist außerordentlich gleichmäßig und besitzt hervorragende Wasch -, WaIk- und Lichtechtheit. In entsprechender Weise läßt sich eine große Anzahl anderer Monoazokombinationen herstellen. Die Färbeeigenschaften der wichtigsten sind aus folgender Tabelle ersichtlich.He dyes wool purple directly in an acidic bath. The color changes during post-treatment with bichromate in blue-black. This coloring is extremely even and has excellent washing, waIk- and lightfastness. A large number of other monoazo combinations can be produced in a corresponding manner produce. The coloring properties of the most important are shown in the following table.
