Description

  

      Verfahren    zur Darstellung einer     Acylaminoverbindung.       Es wurde gefunden, dass man eine neue       Acylaminoverbindung    erhalten kann, wenn  man 1     Mol        1.5-Diaminoanthrachinon    mit  2     Mol    einer Verbindung der allgemeinen  Formel    in der R ein bei der Umsetzung sich ab  spaltender Rest ist, umsetzt.  



  Die Reaktion wird zweckmässig bei Gegen  wart von Verdünnungsmitteln, z. B.     Nitro-          benzol,        Dichlor-,        Trichlorbenzol    oder     Naph-          talin,    ausgeführt. Ferner kann man säure  bindende Mittel, sowie Katalysatoren, wie  Kupfer oder seine Verbindungen, zusetzen.  



  Das     Acylamin    löst sich in Schwefelsäure  mit oranger Farbe und färbt aus violetter       güpe    Baumwolle in sehr kräftigen,     rotstichig     gelben Tönen von sehr guten Echtheitseigen  schaften.    <I>Beispiel:</I>  20 Teile     Chinolin-6-karbonsäurechlorid     werden in 250-300 Teilen Nitrobenzol sus  pendiert. Man fügt 12 Teile 1 .     5-Diamino-          anthrachinon    hinzu und erhitzt unter Rühren  und     Rückflusskühlung    so lange zum Sieden,  bis die     Chlorwasserstoffentwicklung    aufgehört  hat.

   Man saugt das noch heisse Reaktions  gemisch ab und wäscht das zurückbleibende  gelbe Reaktionsprodukt mit heissem     Nitro-          benzol    und dann mit Alkohol gut aus. Es  lässt sich durch     Umkristallisieren    in     Chinolin     oder ähnlichen hochsiedenden Lösungsmitteln  oder auch durch Behandeln mit     Natrium-          hypochloritlösung    erforderlichenfalls reinigen.  



  An Stelle des     Chinolin-6-karbonsäure-          chlorids    kann man auch     Chinolin-6-karbon-          säure    oder ihre Ester oder     Chinolin-6-karbon-          säureanhvdrid    verwenden.

      Process for the preparation of an acylamino compound. It has been found that a new acylamino compound can be obtained if 1 mole of 1,5-diaminoanthraquinone is reacted with 2 moles of a compound of the general formula in which R is a radical which splits off during the reaction.



  The reaction is expedient in the presence of diluents such. B. nitrobenzene, dichlorobenzene, trichlorobenzene or naphthalene performed. Acid-binding agents and catalysts such as copper or its compounds can also be added.



  The acylamine dissolves in sulfuric acid with an orange color and dyes violet güpe cotton in very strong, reddish yellow tones with very good fastness properties. <I> Example: </I> 20 parts of quinoline-6-carboxylic acid chloride are suspended in 250-300 parts of nitrobenzene. You add 12 parts 1. 5-diamino anthraquinone added and heated to boiling with stirring and reflux cooling until the evolution of hydrogen chloride has ceased.

   The still hot reaction mixture is filtered off with suction and the yellow reaction product that remains is washed thoroughly with hot nitrobenzene and then with alcohol. If necessary, it can be purified by recrystallization in quinoline or similar high-boiling solvents or by treatment with sodium hypochlorite solution.



  Instead of the quinoline-6-carbonic acid chloride, quinoline-6-carbonic acid or its esters or quinoline-6-carbonic acid anhydride can also be used.
