Description

  

  Verfahren zur Herstellung eines     Wo11farbstbfes    der     Antliracliinoni#eihea       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Wollfarb-          stoffes    der     Anthi#acbirionreihe,    dadurch ge  kennzeichnet, dass man     1-amino-4-(4'-äthyl-          aminophenyl)-aininoanthrachirion-2-sulfosaures     Natrium mit einem     Acetylierungsmittel    be  handelt.  



  Der neue     Farbstoff    färbt Wolle aus saurem  Bade in     rotstichig    blauen Tönen an und ist  identisch mit dem Farbstoff, der nach An  gaben der deutschen Patentschrift<B>469565</B>  durch Kondensation von     1-Amino-4-brom-          anthrachinon-2-sulfosäure    mit     Acet-ätbyl-p-          pheny        lendiainin    erhalten wird.  



  <I>Beispiel:</I>  20 kg     Farbstoff,    erhalten durch Konden  sation von     1-Amirio-4-bromanthrachinon-2-          sulfosäure    mit     Äthyl-p-phenylendiamin,    wer  den in 1000 Liter heissem Wasser gelöst und  bei G0-70   allmählich so viel Essigsäure-         anhydrid        zugegeben,    bis vollständige     Acety-          lierung    der einen     Aminogruppe    eingetreten  ist. Der Farbstoff wird mit Hilfe von Koch  salz ausgeschieden.  



  Die     Acetylierung    lässt sich mit gleichem  Erfolg auch so durchführen, dass     inau    den       .Ausgangsfarbstoff    in     Pyridiii    löst und mach  Zugabe von     Acetylchlorid    einige Zeit bei  gewöhnlicher     Temperatur    rühren lässt. Nach  Verdünnen mit Wasser lässt sich der     acetylierte          Farbstoff    mit Kochsalz     aussalzeu.  



  Process for the production of a wool dye of the Antliracliinoni # eihea The present patent relates to a process for the production of a wool dye of the Anthi # acbirion series, characterized in that 1-amino-4- (4'-ethyl-aminophenyl) -aininoanthrachirion- Sodium 2-sulfonic acid is treated with an acetylating agent.



  The new dye dyes wool from acid baths in reddish-tinged blue shades and is identical to the dye which, according to German patent specification <B> 469565 </B>, is produced by condensation of 1-amino-4-bromo-anthraquinone-2- sulfonic acid with acet-ätbyl-p-pheny lendiainin is obtained.



  <I> Example: </I> 20 kg of dye, obtained by condensation of 1-Amirio-4-bromoanthraquinone-2-sulfonic acid with ethyl-p-phenylenediamine, are dissolved in 1000 liters of hot water and gradually at G0-70 as much acetic anhydride is added until complete acetylation of one amino group has occurred. The dye is excreted with the help of common salt.



  The acetylation can also be carried out with the same success in such a way that inau the starting dye dissolves in Pyridiii and the addition of acetyl chloride can be stirred for some time at ordinary temperature. After dilution with water, the acetylated dye can be salted out with common salt.
