Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen  Farbstoff der     Anthrachinonreihe    - das An  thrachinon-2,2'-1,1'-naphthacridon - erhält,  wenn man bei     1-a-Naphthylaminoanthrachi-          non-2-carbonsäure    den     Ringschluss    zu     Acridon     vornimmt, durch Behandeln der Säure mit  kondensierend wirkenden Mitteln.

   Der so  erhaltene     Farbstoff    kann durch     Umkristalli-          sieren    aus Nitrobenzol in     bordeauxfarbenen     Kristallen erhalten werden, die die Baum  wolle aus     violettroter        güpe    Bordeaux färben.  Die schwefelsaure Lösung, in Wasser ein  getragen, scheidet     bordeauxfarbene    Flocken  aus.  



       Beispiel:     39,3 Gewichtsteile     1-a-Naphthylamino-          anthrachinon-2-carbonsäurewerdeneingetragen     in eine Mischung, bestehend aus 400 Gewichts  teilen     Toluol    und 13 Gewichtsteilen     Thionyl-          ehlorid.    Man erwärmt auf<B>50',</B> hält 1 Stunde  bei     50-520,    heizt dann zum     Rückfluss    und  hält '/4 Stunde.

   Nachdem heiss abgesaugt  wurde, wäscht man mit     Toluol,    Alkohol und    Wasser, behandelt den Rückstand zur Ent  fernung von eventuell nicht umgesetzter       Carbonsäure    mit verdünnter     Natriumhydro-          xydlösung,    wäscht dann heiss mit Wasser  neutral und trocknet.  



  Die     -1-a-Naphthylaminoanthrachinon-2-          carbonsäure    kann wie folgt hergestellt werden:  44 Gewichtsteile     1-Aminoanthrachinon-2-          carbonsäureäthylester,    24 Gewichtsteile     Na-          triumcarbonat,    1,5 Gewichtsteile Kupfer  chlorid (wasserfrei) und 125 Gewichtsteile       1-Chlornaphthalin    werden 4 Stunden rück  fliessend gekocht; anschliessend wird die Masse  mit Wasserdampf destilliert, der Rückstand  abgesaugt, mit heissem Wasser neutral ge  waschen, mit Salzsäure gedeckt, wieder neu  tral gewaschen und getrocknet.

   Der so er  haltene     1-a-Naphthylaminoanthrachinon-2-          carbonsäureäthylester    stellt ein dunkles vio  lettes Pulver dar und löst sich in Schwefel  säure olive. Durch Verdünnen der schwefel  sauren Lösung mit Wasser fallen rotbraune  Flocken aus.

        42 Gewichtsteile     1-a-Naphthylamirroan-          thrachirron    - 2 -     carbonsäureäthylester    werden  in 600 Gewichtsteilen Alkohol mit 15 Ge  wichtsteilen 30     o%igerNatriumbydroxydlösung     1 Stunde rückfliessend gekocht und heiss ab  gesaugt; das Filtrat wird mit Wasser ver  dünnt und der Alkohol     abdestilliert.    Die Lö  sung wird von wenig Rückstand filtriert,  das Filtrat mit Salzsäure angesäuert, filtriert,  neutral gewaschen und getrocknet. Die so  erhaltene rohe     1-a-Naphthylamirroantbrachi-          non-2-carbonsäure    kann z. B. durch Extrak  tion mit Alkohol gereinigt werden; sie ver  hält sich gegenüber Schwefelsäure wie der  Ester.



  Process for the production of a new dye of the anthraquinone series. It has been found that a new dye of the anthraquinone series - the anthraquinone-2,2'-1,1'-naphthacridone - is obtained when 1-a-naphthylaminoanthraquinone-2-carboxylic acid closes the ring to acridone, by treating the acid with condensing agents.

   The dye thus obtained can be obtained by recrystallization from nitrobenzene in burgundy-colored crystals, which color the cotton from a violet-red güpe bordeaux. The sulfuric acid solution, absorbed in water, separates out burgundy colored flakes.



       Example: 39.3 parts by weight of 1-a-naphthylamino-anthraquinone-2-carboxylic acid are introduced into a mixture consisting of 400 parts by weight of toluene and 13 parts by weight of thionyl chloride. The mixture is heated to 50 ', held at 50-520 for 1 hour, then heated to reflux and held for 1/4 hour.

   After it has been suctioned off while hot, it is washed with toluene, alcohol and water, the residue is treated with dilute sodium hydroxide solution to remove any unreacted carboxylic acid, then washed hot with water until neutral and dried.



  The -1-α-naphthylaminoanthraquinone-2-carboxylic acid can be prepared as follows: 44 parts by weight of ethyl 1-aminoanthraquinone-2-carboxylate, 24 parts by weight of sodium carbonate, 1.5 parts by weight of copper chloride (anhydrous) and 125 parts by weight of 1-chloronaphthalene are 4 Cooked backwards for hours; the mass is then distilled with steam, the residue is filtered off with suction, washed neutral with hot water, covered with hydrochloric acid, washed neutral again and dried.

   The 1-a-naphthylaminoanthraquinone-2-carboxylic acid ethyl ester thus obtained is a dark violet powder and dissolves in sulfuric acid olive. By diluting the sulfuric acid solution with water, red-brown flakes precipitate.

        42 parts by weight of 1-a-naphthylamirroanthrachirron - 2 - carboxylic acid ethyl ester are refluxed for 1 hour in 600 parts by weight of alcohol with 15 parts by weight of 30% strength sodium hydroxide solution and sucked off hot; the filtrate is diluted with water and the alcohol is distilled off. The solution is filtered from a little residue, the filtrate is acidified with hydrochloric acid, filtered, washed neutral and dried. The crude 1-a-naphthylamirroantbrachi- non-2-carboxylic acid thus obtained can, for. B. be cleaned by extraction with alcohol; it behaves like the ester to sulfuric acid.
