Description

  

      Zusatzpatent    zum Hauptpatent Nr. 208544.    Verfahren zur Herstellung eines     stickstoffhaltigen    Kondensationsproduktes.    Es wurde     gefunden,    dass man ein     stick-          stoffhaltiges     herstel  len kann, wenn man 1     Mol        1,3-Dihalegen-2-          methylanthrachinon    mit 2 Mal     1-Amino-5-          benzoylaminoanthrachinon        umsetzt.    Der neue  Farbstoff ist     ein,dunkelbraunes    Pulver,

   das  sich in Schwefelsäure mit     braunoliver    Farbe  löst und Baumwolle aus brauner     Küpe    in  echten braunen Farbtönen färbt.  



  Als     1,3-Dihalogen-2-methylanthrachinon     kann     beispielsweise        1,3-Dichlor-2-methyl-          anthrachinon    verwendet werden.  



  Die Umsetzung mit     1-Amino:-5-benzoyl-          aminoanthrachinon        erfolgt    zweckmässig in  Gegenwart von     Lösungs-    oder     Verteilungs-          mitteln,    z. B. Nitrobenzol,     Dichlarbenzol    oder  Naphthalin und in     Gegenwart    von Katalysa  toren, wie Kupfer oder Kupferverbindungen,  sowie vorzugsweise in Anwesenheit von  säurebindenden     Mitteln,    wie     Natriumacetat     und     Alkalicarbonat,    bei     höherer    Temperatur.

           Beispiel:     14,5 Teile     1,3-Dichlor-2-methylanthra-          ehinon,    34,5 Teile     1-Amino    5-benzoylamino-         anthrachinon,    40     Teile        wasserfreies    Natrium  carbonat, 1 Teil     Kupferacetat    und 300 Teile  Naphthalin werden 18     Stunden    zum Sieden  erhitzt.

   Das     Reaktionsgemisch        wird    noch  heiss mit 300     Teilen    Chlorbenzol     verdünnt     und bei 90-100       filtriert.    Der Rückstand  wird mit Chlorbenzol sowie     mit    Alkohol ge  waschen, mit Wasser     ausgekocht,    filtriert  und getrocknet.



      Additional patent to main patent No. 208544. Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing one can be produced if 1 mole of 1,3-dihalogen-2-methylanthraquinone is reacted with 2 times 1-amino-5-benzoylaminoanthraquinone. The new dye is a dark brown powder

   which dissolves in sulfuric acid with a brown-olive color and dyes cotton from a brown vat in real brown shades.



  1,3-dichloro-2-methyl-anthraquinone, for example, can be used as 1,3-dihalo-2-methylanthraquinone.



  The reaction with 1-amino: -5-benzoylaminoanthraquinone is expediently carried out in the presence of solvents or distributing agents, e.g. B. nitrobenzene, dichlorobenzene or naphthalene and in the presence of cata factors, such as copper or copper compounds, and preferably in the presence of acid-binding agents such as sodium acetate and alkali metal carbonate, at a higher temperature.

           Example: 14.5 parts of 1,3-dichloro-2-methylanthraquinone, 34.5 parts of 1-amino 5-benzoylamino anthraquinone, 40 parts of anhydrous sodium carbonate, 1 part of copper acetate and 300 parts of naphthalene are heated to the boil for 18 hours .

   The reaction mixture is diluted while still hot with 300 parts of chlorobenzene and filtered at 90-100. The residue is washed with chlorobenzene and with alcohol, boiled with water, filtered and dried.
