Gegenstand vorliegender Erfindung bildet ein Verfahren zur Darstellung eines Substantiven schwarzen Baumwollfarbstoffs, welches an folgendem Beispiele erläutert wird.The present invention provides a method for representing a noun black cotton dye, which is illustrated by the following examples.
35 kg Diphenylthioharnstoff und 30 kg m- * Dinitrochlorbenzol werden in etwa 500 1 Alkohol gelöst, mit 25 kg Natriumacetat versetzt und am Rückfiufskühler einige Stunden gekocht.35 kg diphenylthiourea and 30 kg m- * Dinitrochlorobenzene is dissolved in about 500 liters of alcohol, mixed with 25 kg of sodium acetate and cooked on the reflux condenser for a few hours.
Nach etwa 2 Stunden läfst man erkalten, filtrirt die abgeschiedene hellgelbe Verbindung ab und wäscht mit etwas verdünntem Alkohol und Wasser aus. Die so erhaltene Verbindung kann aus Alkohol umkrystallisirt werden und wird dabei in derben, hellgelben Krystallen vom F. P. 191,5° erhalten.After about 2 hours it is allowed to cool, and the separated pale yellow compound is filtered and wash off with a little diluted alcohol and water. The compound thus obtained can be recrystallized from alcohol and thereby becomes coarse, pale yellow crystals obtained from the F.P. 191.5 °.
30 kg dieser getrockneten Verbindung trägt man allmählich in die Lösung von 30 kg Schwefel und 120 kg Schwefelnatrium (Na2 S -f- 9 aq) in wenig Wasser ein, erwärmt allmählich auf i2o°, alsdann, nachdem die Reaction milder geworden ist, auf etwa 1500 und hält so lange bei dieser Temperatur, bis die Schmelze trocken geworden ist; gepulvert kann sie direct zum Färben verwendet werden; sie erzeugt auf Baumwolle ein echtes, intensives Schwarz. Der Farbstoff ist in Alkohol wenig, in Wasser leicht mit schwarzgrüner Farbe löslich, die auf Zusatz von Natronlauge nach blauschwarz umschlägt. Die Lösung des Farbstoffs in Schwefelsäure zeigt eine schmutziggrüne Farbe, beim Verdünnen mit Wasser scheidet sich ein grünschwarzer Niederschlag ab. 30 kg of this dried compound are gradually added to the solution of 30 kg of sulfur and 120 kg of sodium sulphide (Na 2 S -f- 9 aq) in a little water, heated gradually to 120 °, then after the reaction has become milder about 150 0 and holds at this temperature until the melt has become dry; powdered, it can be used directly for dyeing; it creates a real, intense black on cotton. The dye is sparingly soluble in alcohol and slightly soluble in water with a black-green color, which turns blue-black on the addition of sodium hydroxide solution. The solution of the dye in sulfuric acid shows a dirty green color, when diluted with water a greenish-black precipitate separates out.
