Description

  

  Verfahren zur Darstellung eines Farbstoffes der     Anthrachinonreihe.       Es wurde gefunden, dass man durch  Kondensation der     1-Ainiiio-4-halogenarithra-          chinon-2-sulfosäure    mit     m-Aminobenzonitril     einen Farbstoff erhält, der sich durch gute  Löslichkeit und durch gutes     Egalisierungs-          vermögen    auszeichnet.  



  <I>Beispiel:</I>  10 Gewichtsteile     1-Amino-4-bromanthra-          chinon-2-sulfosäure,    5 Gewichtsteile     m-Amino-          benzonitril,    13 Gewichtsteile     Natriumbicarbo-          nat    und 0,5 Gewichtsteile     Kupferchlorür    wer  den in 140 Gewichtsteilen Wasser bei ge  wöhnlicher Temperatur 1 Stunde lang gut  verrührt und sodann langsam auf 80   ge  bracht und unter Rühren bei dieser Tempe  ratur zirka 3-4 Stunden lang gehalten.

   Der       Farbstoff    scheidet sich während der Reaktion    nach und nach in blauen Nadeln ab und wird  heiss     abfiltriert.    Durch     Umlösen    aus Wasser  wird das Produkt gereinigt. Aus saurem Bade  färbt das     Kondensationsprodukt    Wolle in       rotstichig    blauer Nuance an.



  Process for the preparation of a dye of the anthraquinone series. It has been found that the condensation of 1-amino-4-haloarithraquinone-2-sulfonic acid with m-aminobenzonitrile gives a dye which is characterized by good solubility and good leveling capacity.



  <I> Example: </I> 10 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid, 5 parts by weight of m-aminobenzonitrile, 13 parts by weight of sodium bicarbonate and 0.5 part by weight of copper chloride are in 140 parts by weight of water Stirred well at the usual temperature for 1 hour and then slowly brought to 80 and kept stirring at this temperature for about 3-4 hours.

   During the reaction, the dye gradually separates out in blue needles and is filtered off while hot. The product is cleaned by dissolving it in water. From an acid bath, the condensation product stains wool in a reddish blue shade.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farb stoffes der Anthrachirionreilie, dadurch ge kennzeichnet; dass man 1-Amino-4-lialogen- anthrachinon-2-sulfosäure niit in-Aniinoberizo- nitril umsetzt. Der neue Farbstoff bildet blaue Nadeln, und färbt aus saurem Bade Wolle in rotstichig blauer Nuance an. PATENT CLAIM: Process for the representation of a dye of the Anthrachirionreilie, characterized in it; that 1-amino-4-halogeno-anthraquinone-2-sulfonic acid is converted into aniinoberizonitrile. The new dye forms blue needles and dyes wool in a reddish blue shade from acidic bath.
