Description

  

  Verfahren zur Darstellung einer neuen     Kupferamminkomplexazoverbindung.       Es wurde gefunden, dass man zu einer  neuen     Kupferaminkomplexazoverbindung    ge  langen kann, die zur Färberei, Druckerei  und zur Schädlingsbekämpfung sich eignet,       indem    man 1     Mol        diazotierte        5-Sulfo-2-amino-          benzoesäure,    1     Mol        2-Oxynaphtalin    und     Te-          tramrnincuprisulfat    aufeinander einwirken lässt.

    <I>Beispiel</I>  Man bereitet eine Lösung des     Tetram-          mincuprisulfats    aus 210     (äewichtsteilen    kristal  lisiertem Kupfersulfat in wenig Wasser und  setzt 430     Volumteile        20o/oiges    Ammoniak  wasser zu der erkalteten     Lösung;    es bildet  sich eine tiefblaue Lösung des     Tetrammin-          cuprisulfats;

      diese gibt man zu einer erkal  teten     wässrigen    Lösung von     2-Naphtolnatrium,     hergestellt aus 144 Gewichtsteilen     2-Naph-          tol        durch    Zusatz der zur     Auflösung    hin  reichenden     Menge    Natronlauge.

   Nach Zugabe  von 700     (xewichtsteilen        kalzinierter    Soda  kuppelt man in einer in der üblichen Weise  hergestellten Lösung der     Diazoverbindung     aus 217 Gewichtsteilen     5-SulFo-2-aminobenzoe-          säure.    Die Bildung des     Azokörpers    und seine    Bindung an den     Kupferamminkomplex    er  folgen sehr rasch, wobei die neue     Kupferam-          minkomplegazoverbindung    in schön kristal  lisierten bräunlichen Blättchen ausfällt. Sie  löst sich in Wasser mit     gelbstichig    brauner  Farbe, in konzentrierter Schwefelsäure rot  stichig-violett.



  Process for the preparation of a new copper amine complex azo compound. It has been found that a new copper amine complex azo compound can be obtained which is suitable for dyeing, printing and pest control by adding 1 mol of diazotized 5-sulfo-2-aminobenzoic acid, 1 mol of 2-oxynaphthalene and tetramrnine cupric sulfate to one another can act.

    <I> Example </I> A solution of tetramine cupric sulfate is prepared from 210 parts by weight of crystallized copper sulfate in a little water and 430 parts by volume of 20% ammonia water are added to the cooled solution; a deep blue solution of the tetrammine cupric sulfate is formed ;

      this is added to a cooled aqueous solution of 2-naphthol sodium, prepared from 144 parts by weight of 2-naphthol by adding the amount of sodium hydroxide solution sufficient for dissolution.

   After adding 700 parts by weight of calcined soda, coupling is carried out in a solution of the diazo compound prepared in the customary manner from 217 parts by weight of 5-SulFo-2-aminobenzoic acid. The formation of the azo body and its binding to the copper amine complex take place very quickly, with the A new copper amine complex precipitates in nicely crystallized brownish flakes, which dissolves in water with a yellowish brown color, in concentrated sulfuric acid it is reddish-purple.

PATENTANSPRUCH: Verfahren zur Darstellung einer neuen Kupferamminkomplexazoverbindung, dadurch gekennzeichnet, dass man 1 Mol der diano tierten 5-Sulfo-2-aminobenzoesäure, 1 Mol 2 Oxyr)aphtalin und Tetrammincuprisulfat auf einander einwirken lässt. Die so erhaltene Kupferarnminkomplexazoverbindung ist für die Färberei, Druckerei und als Schädlingsbe kämpfungsmittel verwendbar. Sie kristallisiert in bräunlichen Blättchen und löst sich in Wasser mit gelbstichig-brauner Farbe in konzentrierter Schwefelsäure rotstichig-violett. PATENT CLAIM: Process for the preparation of a new copper ammine complex azo compound, characterized in that 1 mol of the diano-based 5-sulfo-2-aminobenzoic acid, 1 mol of 2 oxyr) aphtalin and tetrammine cupric sulfate are allowed to act on one another. The copper amine complex azo compound thus obtained can be used in dyeing, printing and as a pest control agent. It crystallizes in brownish leaves and dissolves in water with a yellowish-brown color in concentrated sulfuric acid, reddish-purple.
