Description

Verfahren zur Herstellung von Anthrachinonfarbstoffen Es wurde gefunden, daß wertvolle saure Wollfarbstoffe erhalten werden, wenn man i -Amino-4-halogenanthrachinon- 2 - sulfosäuren mit 3 # 4 # 5-Trihalogenanilinen umsetzt. Die Umsetzungsprodukte stellen blaue Nadeln dar, die sich in Wasser mit blauer Farbe lösen und Wolle aus saurem Bade blau färben. Der besondere Wert der neuen Farbstoffe liegt in ihrer außerordentlichen Beständigkeit gegen die Einwirkung von Chlor oder chlorabspaltenden Mitteln, wie Chlorkalk. Die Reaktion kann in üblicher Weise, z. B. unter Anwendung von Kupfersalzen als Katalysatoren, durchgeführt werden.Process for the production of anthraquinone dyes It has been found that valuable acidic wool dyes are obtained if i -amino-4-halogenanthraquinone- Reacts 2 - sulfonic acids with 3 # 4 # 5-trihaloanilines. The conversion products represent blue needles that dissolve in water with a blue color and wool turn blue in acidic baths. The special value of the new dyes lies in theirs extraordinary resistance to the effects of chlorine or chlorine-releasing agents Agents such as chlorinated lime. The reaction can be carried out in a conventional manner, e.g. B. using of copper salts as catalysts.

Beispiel io Gewichtsteile i-Amino-4-bromanthrachinon-z-sulfonsäure werden mit 8 Gewichtsteilen 3 # 4 # 5-Trichloranilin, i o Gewichtsteilen Natriumbicarbonat und o,5 Gewichtsteilen Kupferchlorür in einem Gemisch aus ioo Gewichtsteilen Wasser und 5o Gewichtsteilen Äthylalkohol 8 bis i o Stunden unter Rückfiuß gekocht. Man läßt erkalten und saugt den abgeschiedenen Farbstoff (i-Amino-4-(3 # 4- 5-trichloranilido) - anthrachinon - a - sulfonsäure) ab. Derselbe wird zwecks Reinigung in Wasser gelöst und durch Zugabe von Kochsalz ausgesalzen. Er stellt blaue Nadeln dar, die sich in Wasser mit blauer Farbe lösen und Wolle aus saurem Bade in äußerst chlorechten blauen Nuancen anfärben.Example 10 parts by weight of i-amino-4-bromoanthraquinone-z-sulfonic acid with 8 parts by weight of 3 # 4 # 5-trichloroaniline, 10 parts by weight of sodium bicarbonate and 0.5 parts by weight of copper chloride in a mixture of 100 parts by weight of water and 50 parts by weight of ethyl alcohol refluxed for 8 to 10 hours. Man lets cool and sucks the deposited dye (i-amino-4- (3 # 4- 5-trichloroanilido) - anthraquinone - a - sulfonic acid). It is dissolved in water for cleaning and salted out by adding table salt. He represents blue needles that are Dissolve in water with a blue color and wool from an acid bath in extremely chlorine-rich dye blue shades.

Farbstoffe von ganz analogen Eigenschaften werden erhalten, wenn man das 3 # 4 # 5-Trichloranilin ersetzt durch das 3 # 4 - 5-Tribromanilin oder das 3 # 5-Dichlor-4-bromanilin.Dyes of completely analogous properties are obtained if one the 3 # 4 # 5-trichloroaniline replaced by the 3 # 4 - 5-tribromaniline or the 3 # 5-dichloro-4-bromoaniline.
