Description

  

      Verfaln-en    zur Herstellung eines     liupferkomplexsalzes.       Gegenstand vorliegender Erfindung ist  ein Verfahren zur Herstellung eines     Kupfer-          komplexsalzes,    das zur Herstellung von       rnjektionslösungen    Verwendung finden soll,       dadurc'h    gekennzeichnet,     dass    man     Gluco-          lieptonsäur-e    und     Kupferliydroxyd    unter Zu  satz von so viel Natronlauge,     dass    ein     neu-          trallöslielies    Endprodukt entstellt,

   aufein  ander     ein-wirken        lässt.    Zweckmässig verwen  det     maneine        Glucoheptonsäure,    die aus ihrem       Lacton    in der Reaktionslösung gebildet  wurde.  



  Dabei kann das     Kupferhydroxyd    auch in  statu     nascendi    Anwendung finden.    <I>Beispiel:</I>  2,1     gr        Glucoh-eptonsäur-elacton    werden  in<B>10</B> cm'     n-Natronlauge,    gelöst, mit einer  Lösung von<B>1,7</B>     gr    Kupferchlorid in<B>5</B> cm'  Wasser versetzt, mit<B>5</B>     n-Natro-nlauge    schwach  alkalisch gemacht und die Lösung in     Meiliy'I.-          alkohol    gegossen. Der Niederschlag wird    mit Methylalkohol und Äther gewaschen  und getrocknet. Man -erhält ein blaues,  in Wasser mit nahezu neutraler Reaktion  lösliches Pulver, das etwa 14% Kupfer ent  hält.



      Procedure for the production of a Liupfer complex salt. The present invention relates to a process for the production of a copper complex salt which is to be used for the production of injection solutions, which is characterized in that glucoleptonic acid and copper hydroxide are added with the addition of so much sodium hydroxide that a neutral soluble end product is obtained disfigured,

   affect each other. It is advisable to use a glucoheptonic acid which was formed from its lactone in the reaction solution.



  The copper hydroxide can also be used in statu nascendi. <I> Example: </I> 2.1 g glucoh-eptonic acid-elactone are dissolved in <B> 10 </B> cm 'n sodium hydroxide solution, with a solution of <B> 1.7 </B> Gr copper chloride was mixed in <B> 5 </B> cm 'of water, made weakly alkaline with <B> 5 </B> n-sodium hydroxide solution and the solution was poured into Meiliy'I alcohol. The precipitate is washed with methyl alcohol and ether and dried. A blue powder is obtained, which is soluble in water with an almost neutral reaction and contains about 14% copper.
