Description

  

      Zusatzpatent    zum Hauptpatent Nr. 214180.    Verfahren zur Herstellung eines     Nüpenfarbstoiies.       Es wurde gefunden;     dass    ein wertvoller       Küpenfarbstoff        hergestellt    werden kann,  wenn man     2,6-Di-(4'-benzoylamino-1'-anthra-          ehinonyl-)aminodiphenylenoxyd    mit konden  sierenden     Mitteln    behandelt.  



       Der        Farbstoff        bildet        ein        schwarzes     das sich in     konzentrierter    Schwefelsäure  mit grüner Farbe löst. und Baumwolle aus  bordeauxfarbiger     Küpe    in echten violetten  Tönen färbt.  



  Das dem vorliegenden Verfahren als     Aus-          rangsprodukt    dienende     2,6-Di-(4'-benzoyl-          a.mino    -1' -     anthrachinonyl    -)     amino,diphenylen        -          oxyd    kann wie folgt hergestellt werden:

    1,6 Teile     2,6-Dibromdiphenylenoxyd    (er  halten aus     2,6-Diaminodiphenylenoxyddurch          Diazotieren        undUmsetzen        mitKupferbromür)     werden     zusammen.    mit 3,5 Teilen     1-A-mino-4-          benzoylaminoanthrachinon,    1.,2     Teillenwasser-          freier    Soda und 0,2 Teilen     Kupferchlarür    in  50     Teilen    Nitrobenzol verteilt und 8 Stunden  zum Sieden erhitzt.

   Nach dem Erkalten wird  unter Absaugen filtriert, mit Nitrobenzol    sowie mit Benzol und Alkohol gewaschen, der       Rückstand    zur     weiteren    Reinigung mit ver  dünnter Salzsäure und hierauf mit Alkohol  ausgekocht,     abffiltriert,    gewaschen und ge  trocknet. Man erhält ein     blaues    kristallines  Pulver, das sich in konzentrierter Schwefel  säure mit     olivgrauer    Farbe löst.  



  Als     kondensierende    Mittel kommen insbe  sondere diejenigen in Betracht, die zur Her  stellung von Ringschlüssen, wie     Carbazol-          ringschlüssen,    geeignet sind, wie Aluminium  chlorid. gegebenenfalls zusammen mit Alkali  halogeniden,     Benzylcyaniden        und    Säure  chloriden, hauptsächlich aber     konzentrierte     Schwefelsäure sowie ihre Abkömmlinge, wie       Chlorsulfonsäure.     



       Beispiel:     1 Teil des Umsetzungsproduktes aus  7     Mol        2,6-Dibromdiphenylenoxyd    und 2     Mol          1-Amino-4-benzoylaminoanthrachinon    wird  bei<B>0-5'</B> in<B>2</B>7 Teile 100%ige Schwefel  säure eingetragen und 1.6 Stunden bei     18-2.2'     gerührt. Man     trägt    in Eis ein, tropft eine      Lösung von 0,2     Teilen        Natriumnitrit    in     we-          nig    Wasser zu und rührt 3 Stunden bei 0-5  .

    Hierauf setzt man weitere     0.1        \feile    Natrium  nitril=, in     Wassergelöst,    zu und rührt 16     Sl:un-          den    bei 0-5 ". Dann wird filtriert, ausge  waschen und entweder getrocknet oder     ver-          pastc:t.  



      Additional patent to main patent No. 214180. Process for the production of a nub dye. It was found; that a valuable vat dye can be produced by treating 2,6-di- (4'-benzoylamino-1'-anthraquinonyl) aminodiphenylene oxide with condensing agents.



       The dye forms a black color that dissolves in concentrated sulfuric acid with a green color. and cotton from a burgundy vat dyes real violet tones.



  The 2,6-di- (4'-benzoyl- a.mino -1 '- anthraquinonyl -) amino, diphenylene oxide used as the starting product in the present process can be prepared as follows:

    1.6 parts of 2,6-dibromodiphenylene oxide (obtained from 2,6-diaminodiphenylene oxide by diazotizing and reacting with copper bromide) are combined. with 3.5 parts of 1-A-mino-4-benzoylaminoanthraquinone, 1., 2 parts of anhydrous soda and 0.2 parts of copper chloride in 50 parts of nitrobenzene and heated to boiling for 8 hours.

   After cooling, it is filtered with suction, washed with nitrobenzene and with benzene and alcohol, the residue is boiled for further purification with dilute hydrochloric acid and then with alcohol, filtered off, washed and dried. A blue crystalline powder is obtained which dissolves in concentrated sulfuric acid with an olive-gray color.



  Particularly suitable condensing agents are those which are suitable for producing ring connections, such as carbazole ring connections, such as aluminum chloride. optionally together with alkali halides, benzyl cyanides and acid chlorides, but mainly concentrated sulfuric acid and its derivatives, such as chlorosulfonic acid.



       Example: 1 part of the reaction product from 7 moles of 2,6-dibromodiphenylene oxide and 2 moles of 1-amino-4-benzoylaminoanthraquinone becomes <B> 0-5 '</B> in <B> 2 </B> 7 parts 100% ige sulfuric acid entered and stirred for 1.6 hours at 18-2.2 '. It is poured into ice, a solution of 0.2 part of sodium nitrite in a little water is added dropwise and the mixture is stirred at 0-5 for 3 hours.

    A further 0.1% sodium nitrile, dissolved in water, is then added and the mixture is stirred for 16% at 0-5 ". It is then filtered, washed and either dried or pasted.
