Description

  

      Zusatzpatent    zum Hauptpatent Nr. 133477.    Verfahren zur Darstellung einer neuen     Kupferamminkomplegazoverbindung.       Es wurde gefunden, dass man zu einer  neuen     Kupferamminkomplexazoverbindung    ge  langen kann, indem man zunächst 1     Mol     dianotierte     3-Amino-benzoesäure    mit 1     Mol          7.7'-Disulfo-        5.5'-dioxy-2.2-dinaphtylharnstoff     essigsauer kuppelt;

   zu dieser     Azoverbindung     setzt man     Hexammincuprichlorid    und ein     Mol     dianotierte     2-Aminobenzoesäure,    worauf sich  eine     Kupferamminkomplexazoverbindung    bil  det.         Beispiel:     137 Gewichtsteile     3-Amir)obenzoesäure     werden dianotiert und .essigsauer mit 502  Gewichtsteilen     5.5'-Dioxy-2.2'-dinaphtylharn-          stoff-7.7-disulfosäure    gekuppelt.

   Nach been  digter Umsetzung macht man mit 800 Ge  wichtsteilen     kalzinierter    Soda alkalisch, setzt  eine Lösung des     Hexammincuprichlorids,    be  reitet aus 170     Gew:chtsteilen        Cuprichlorid,     hinzu und kuppelt bei     -%5     mit einer in be  kannter Weise hergestellten Lösung der Diazo-         verbindung    aus 137 Gewichtsteilen     2-Amino-          benzoesäure.    Man salzt die klare Farbstoff  lösung, welche keine Spur von unlöslicher),  anorganischen Kupferverbindungen enthält,  aus, filtriert und arbeitet in der üblichen  Weise auf.  



  Die neue     Kupferarnminkomplexazover-          bindung    löst sich in Wasser mit ziegelroter,  in konzentrierter Schwefelsäure mit blaustichig  roter Farbe, sie ist in der Druckerei, Färberei  und als Schädlingsbekämpfungsmittel ver  wendbar.



      Additional patent to the main patent No. 133477. Process for the preparation of a new copper amine complex. It has been found that a new copper amine complex azo compound can be obtained by first coupling 1 mol of dianotated 3-amino-benzoic acid with 1 mol of 7.7'-disulfo-5.5'-dioxy-2.2-dinaphthylurea in acetic acidic acid;

   Hexammine cuprichloride and one mole of dianotated 2-aminobenzoic acid are added to this azo compound, whereupon a copper amine complex azo compound is formed. Example: 137 parts by weight of 3-amir) topzoic acid are dianotized and acetic acid coupled with 502 parts by weight of 5.5'-dioxy-2.2'-dinaphthylurea-7.7-disulfonic acid.

   When the reaction is complete, it is made alkaline with 800 parts by weight of calcined soda, a solution of hexammine cuprichloride, prepared from 170 parts by weight of cuprichloride, is added and, at -% 5, it is coupled with a solution of the diazo compound from 137 prepared in a known manner Parts by weight of 2-amino benzoic acid. The clear dye solution, which does not contain any trace of insoluble, inorganic copper compounds, is salted out, filtered and worked up in the usual way.



  The new copper amine complex azo compound dissolves in water with a brick-red color, in concentrated sulfuric acid with a bluish red color; it can be used in printing, dyeing and as a pesticide.

PATENTANSPRUCH: Verfahren zur Darstellung einer neuen Kupferamminkomplexazoverbindung, dadurch gekennzeichnet, dass man 1 Mol dianotierter 3-Amin öber)zoesäure essigsauer kuppelt mit 1 'Hol 7.7'-Disulfo-5.5'-dioxy-2.2'-dinaphtylharn- stoff und darauf weiter 1 Mol dianotierte 2-Aminobenzoesäure und Hexammincupri- chlorid einwirken lässt. PATENT CLAIM: Process for the preparation of a new copper amine complex azo compound, characterized in that 1 mol of dianotated 3-amine over) zoic acid is coupled with 1 'Hol 7.7'-disulfo-5.5'-dioxy-2.2'-dinaphthylurea and then another 1 mol dianotized 2-aminobenzoic acid and hexammine cupric chloride can act. Die so erhaltene gupferamminkomplexazoverbindung ist für die Färberei, Druckerei und als Schädlingsbe kämpfungsmittel verwendbar und löst sich in Wasser ziegelrot, in konzentrierter Schwefel säure blaustichig rot. The gupferamminkomplexazoverbindungen obtained in this way can be used in dyeing, printing and as a pest control and dissolves brick-red in water and bluish red in concentrated sulfuric acid.
