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.
