Description

  

  Verfahren zur Darstellung eines     Aminoantbrahydrochinonderivates.       Gegenstand vorliegender Erfindung ist  ein Verfahren zur Darstellung eines     Amino-          anthrahydrochinonderivates,    dadurch ge  kennzeichnet,     dass    man     2-Acetyl-a.mino-          anthrachinon    mit     Pyridin-Schwefeltrioxyd     in Gegenwart eines     Metalles    und einer ter  tiären organischen Base behandelt und im  entstandenen Produkt die     Acetylgruppe    ver  seift.  



  <I>Beispiel:</I>  12 Teile von     2-Acetyl-am-ino-anthrachinon     werden mit<B>50</B> Teilen trockenem     Pyridin    und  <B>25</B> Teilen     Pyridin-Sch-#vefelsäurea-nhydrid     gemischt und hierauf die Temperatur unter  Umrühren auf<B>90'</B> erhöht.<B>8</B> Teile von     ge-          pulvertem    Kupfer     -,verden    dann zugesetzt.  



  2n       und    die Schmelze während einer Stunde auf  einer Temperatur von<B>90 '</B> erhalten. Sie wird  dann mit ungefähr 250 Teilen Wasser, wel  ches<B>13</B> Teile     Atznatron,    enthält, verdünnt  und hierauf zum Entfernen des     Pyridins    mit  Dampf destilliert, wobei das Volumen un  gefähr konstant gehalten und die heisse Lö-         sung    sodann von den Kupferrückständen  durch Filtrieren befreit wird.

   Diese     Lösuno,     enthält das     Natriumsalz    des     '2-Acetyl-amino-          alithrahydrochinon-Schwefelsä,urees        ters.        Züi     dieser Lösung werden nun<B>10</B> Teile     Natrium-          hydroxyd    zugesetzt und das Ganze wäh  rend einer Stunde gekocht, wodurch die       Acotylgruppe    verseift wird, während die       Sollweielsäuregruppen    praktisch unverändert  bleiben.  



  Textilerzeugnisse, welche mit dieser Lö  sung imprägniert sind,     -v#,erdeil    mit einem  leuchtenden,     bräunliAgelben    Ton gefärbt.  welcher nach dem Eintauchen in kochende  saure     Kupfersulfatlösung    in leuchtend blaue  Nuancierungen verwandelt wird, welche eine  sehr gute Fixierung auf der Faser auf  weisen.  



  Die konzentrierte wässerige     Lösuno,    des       Natriunisalzes    des neuen Körpers ist braun  und wird beim Verdünnen gelb mit grüner       tn     Fluoreszenz. Auf Zusatz von     Kaliumehlorid         wird das     Kaliumsalz    in Form von gelben  Kristallen     ausgesalzen.     



  Die Verbindung soll als     Zwiselienprodukt     für die Herstellung von Farbstoffen Ver  wendung finden.



  Process for the preparation of an aminoantbrahydroquinone derivative. The present invention relates to a process for the preparation of an amino anthrahydroquinone derivative, characterized in that 2-acetyl-a.mino-anthraquinone is treated with pyridine-sulfur trioxide in the presence of a metal and a tertiary organic base and the acetyl group in the resulting product soaps.



  <I> Example: </I> 12 parts of 2-acetyl-am-ino-anthraquinone are mixed with <B> 50 </B> parts of dry pyridine and <B> 25 </B> parts of pyridine-sulfuric acid a -nhydride mixed and then the temperature increased to <B> 90 '</B> while stirring. <B> 8 </B> parts of powdered copper - are then added.



  2n and the melt is kept at a temperature of <B> 90 '</B> for one hour. It is then diluted with approximately 250 parts of water, which contains 13 parts of caustic soda, and then distilled with steam to remove the pyridine, the volume being kept approximately constant and the hot solution then by the copper residue is freed by filtration.

   This solution contains the sodium salt of 2-acetyl-amino-alithrahydroquinone-sulfuric acid. <B> 10 </B> parts of sodium hydroxide are now added to this solution and the whole is boiled for one hour, which saponifies the acotyl group while the Sollwielic acid groups remain practically unchanged.



  Textile products, which are impregnated with this solution, -v #, earthy colored with a bright, brownish-yellow tone. which after immersion in boiling acidic copper sulphate solution is transformed into bright blue shades, which have a very good fixation on the fiber.



  The concentrated aqueous solution of the sodium salt of the new body is brown and, when diluted, turns yellow with green fluorescence. When potassium chloride is added, the potassium salt is salted out in the form of yellow crystals.



  The compound is said to be used as an intermediate product for the manufacture of dyes.
