Description

  

  Verfahren zur Herstellung eines     stiekstofflialtigen    Kondensationsproduktes.    Es wurde gefunden, dass man     ein    wert  volles stickstoffhaltiges     Köndensationspro-          dukt    erhält, wenn man ein     ms-Halogen-2    . 3  phthaloylchinolin mit     2-Aminoanthrachinon     kondensiert.  



       Die    Kondensation wird zweckmässig in  Gegenwart von     Lösungs-    oder Verdünnungs  mitteln durchgeführt, gegebenenfalls können  auch säurebindende Mittel oder reaktions  fördernde Stoffe, wie Kupferverbindungen,  zugesetzt werden,  Das erhaltene Kondensationsprodukt löst  sich in konzentrierter Schwefelsäure mit  orangeroter Farbe und liefert aus schwarz  grüner     Küpe    auf Baumwolle ein     rotstichiges     Gelb von sehr guten Echtheitseigenschaften.

         Beispiel:     Eine Mischung aus 58 Teilen     ms-Chlor-          2.        3-phthaloylchinolin    (erhältlich durch Kon  densation von     a-Naphthochinon    mit     Anthranil-          säure,

          Ringschluss    der entstandenen     Naphtho-          chinonylanthranilsäure    mit konzentrierter  Schwefelsäure zum     Benzakridonchinon    und    Umsetzung des erhaltenen     Benzakridonchi-          nons    mit     Phosphorpentachlorid    oder     Thionyl-          chlorid),    44 Teilen     2-Aminoanthrachinon    und  <B>1000</B> Teilen     Nitrobenzol    wird so lange zum  Sieden erhitzt, bis keine Salzsäure mehr ent  weicht. Nach, dem Erkalten wird abgesaugt,  der Rückstand mit Alkohol gewaschen und  aus Nitrobenzol umkristallisiert.



  Process for the production of a high-strength condensation product. It has been found that a valuable nitrogenous condensation product is obtained if an ms-halogen-2. 3 phthaloylquinoline condensed with 2-aminoanthraquinone.



       The condensation is expediently carried out in the presence of solvents or diluents, acid-binding agents or substances that promote reactions, such as copper compounds, can optionally also be added. The condensation product obtained dissolves in concentrated sulfuric acid with an orange-red color and gives off a black-green vat on cotton reddish yellow with very good fastness properties.

         Example: A mixture of 58 parts of ms-chloro-2. 3-phthaloylquinoline (obtainable by condensation of a-naphthoquinone with anthranilic acid,

          Ring closure of the resulting naphthoquinonylanthranilic acid with concentrated sulfuric acid to form benzakridonequinone and reaction of the benzacridonequinone obtained with phosphorus pentachloride or thionyl chloride), 44 parts of 2-aminoanthraquinone and 1000 parts of nitrobenzene are heated to the boil until no more hydrochloric acid escapes. After cooling, it is filtered off with suction, the residue is washed with alcohol and recrystallized from nitrobenzene.
