Description

  

  Verfahren zur Darstellung eines     Chromierungsfarbstofes    der     Antlirachinonogazolreibe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  eines     Chromierungsfarbstoffes    der     Anthra-          chinonoxazolreihe,    welches dadurch gekenn  zeichnet ist,

   dass man auf das durch Konden  sation von     1-Oxy-2.4-diamino-anthrachinon     mit     o-Chlorbenzoylchlorid    und anschliessende       Verseifung    der     Acyla.minogruppe    erhältliche       Amino-anthrachinonoxazol        Schwefeltrioxyd     enthaltende Schwefelsäure     einwirken    lässt.  



  <I>Beispiel:</I>  Das analog dem Verfahren des Schweizer  Patentes Nr. 184017 erhältliche     Anthrachi-          nonoxazol    aus     1-Oxy-2.        4-diamino-anthrachi-          non    und     o-Chlorbenzoylchlorid    wird mit  Schwefelsäure verseift,

   und das so erhaltene  Amin vom Schmelzpunkt 308   C wird dann  mit 20     %        igem        Oleum    zirka 1 Stunde lang bei  <B>130</B>   C     sulfiert.    Der über das     Natriumsalz     gereinigte Farbstoff ergibt auf Wolle nach    der     Chromierung    ein     graustichiges    Blau von  guten Echtheitseigenschaften.



  Process for the preparation of a chromating dye of the antlirachinonogazole grater. The subject of the present additional patent is a process for the preparation of a chromating dye of the anthraquinone oxazole series, which is characterized by

   that the amino-anthraquinone-oxazole-sulfuric acid containing sulfuric acid, obtained by condensation of 1-oxy-2,4-diamino-anthraquinone with o-chlorobenzoyl chloride and subsequent saponification of the Acyla.minogruppe, is allowed to act.



  <I> Example: </I> The anthraquinoneoxazole obtained from 1-oxy-2 analogously to the process of Swiss patent no. 184017. 4-diamino-anthraquinone and o-chlorobenzoyl chloride are saponified with sulfuric acid,

   and the amine thus obtained, having a melting point of 308 ° C., is then sulfated with 20% strength oleum at 130 ° C. for about 1 hour. The dye, purified using the sodium salt, gives a grayish blue with good fastness properties on wool after chromating.
