Description

  

  Verfahren zur Darstellung eines     Chromierungsfarbstoffes    der     Anthraehinonogazolieihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Chromie-          rungsfa,rbstoffes    der     Anthrachinonoxazol-          reihe,    dadurch gekennzeichnet,

   dass man auf  das durch Kondensation von     1-Oxy-2.        4-di-          amino-anthrachinon    mit     m-1Tethoxybenzoyl-          ehlorid    und anschliessende     Verseifung    der       Acylaminogruppe    erhältliche     Amino-anthra-          chinonoxazol        Schwefeltrioxyd    enthaltende  Schwefelsäure einwirken lässt.  



  <I>Beispiel:</I>  Das analog dem Verfahren des Schweizer  Patentes Nr. 184017 erhältliche     Anthrachi-          nonoxazol    aus     1-Oxy-92    .     4-diaminoa.nthrachi-          non    und     m-Methoxy-benzoylchlorid    wird mit  Schwefelsäure verseift und liefert ein Amin,  das nach dem     Umkristallisieren    aus     Dichlor-          benzol    den Schmelzpunkt von 325   aufweist.  Dieses Amin wird     1i/2    Stunde in der     15-          fachen    Menge 20%igem     Oleum    auf 95 bis  100   C erhitzt.

   Man gibt dann auf wenig       Ei;s,    saugt den Niederschlag a .b, löst wieder  in heissem Wasser und fällt die     Sulfosäure       des Farbstoffes als     Kaliumsalz    aus.     -Man    er  hält so einen     Chromierfarbstoff,    der auf  Wolle blaugraue Farbtöne von guten     fär-          berischen    Eigenschaften und sehr guter  Lichtechtheit färbt.



  Process for the preparation of a chromating dye of the anthraquinonogazole series. The subject of this additional patent is a process for the preparation of a chromating dye of the anthraquinone oxazole series, characterized in that

   that one can rely on the condensation of 1-oxy-2. 4-di-amino-anthraquinone with m-1-thoxybenzoyl chloride and subsequent saponification of the acylamino group, amino-anthraquinone-oxazole sulfuric acid containing sulfuric acid can act.



  <I> Example: </I> The anthraquinoneoxazole obtained from 1-oxy-92 analogous to the process of Swiss patent no. 184017. 4-diaminoa.nthrachinone and m-methoxy-benzoyl chloride are saponified with sulfuric acid and give an amine which, after recrystallization from dichlorobenzene, has a melting point of 325. This amine is heated to 95 to 100 ° C. for 1½ hour in 15 times the amount of 20% strength oleum.

   One then adds a little egg, sucks the precipitate a .b, dissolves again in hot water and the sulfonic acid of the dye precipitates as the potassium salt. - You get a chroming dye that dyes wool on blue-gray shades with good coloring properties and very good lightfastness.

PATENTANSPRUCH: Verfahren zur Darstellung eines Chro- mierungsfarbstoffes der Anthrachinonoxazol- reihe, dadurch gekennzeichnet, PATENT CLAIM: Process for the preparation of a chromizing dye of the anthraquinone oxazole series, characterized in that dass man auf das durch Kondensation von 1-0$y-2 .4-di- aminoanthracIiinon mit m-Methoxybenzoyl- chlorid und anschliessende Verseifung der Acylaminogruppe erhältliche Aminoanthra- chinonoxazol Schwefeltrioxyd enthaltende Schwefelsäure einwirken lässt. the sulfuric acid containing sulfuric acid, obtainable by condensation of 1-0 $ y-2 .4-di-aminoanthracinone with m-methoxybenzoyl chloride and subsequent saponification of the acylamino group, is allowed to act. Die so erhältliche Farbstoffsulfosäure löst sich in Wasser und gibt auf Wolle nach der Chromierung blaugraue Farbtöne von guten färberischen Eigenschaften und sehr guter Lichtechtheit. The dye sulfonic acid obtainable in this way dissolves in water and, after chroming, gives wool to blue-gray shades of good dyeing properties and very good lightfastness.
