Description

  

  Verfahren zur Darstellung von     4-Glykolylamino-3'-amino-4'-ogy-arsenobenzol..       Gegenstand dieses Patentes ist ein Ver  fahren zur Darstellung von     4-Glykolyl-          amino-3'-amino-4'-oxyarsenobenzol,    dadurch  gekennzeichnet, dass man     4-Glykolylamino-          benzolarsin        mit        4-Oxy-3-aminobenzol-l-di-          chlorarsin    kondensiert.  



  Das Endprodukt ist ein gelbes, in ver  dünnter Natronlauge leicht lösliches Pulver.  Es zeichnet sich durch     geringe    Giftigkeit  und hohen Heilwert aus.  



  <I>Beispiel:</I>  55     gr        4-Glykolylaminobenzol-l-arsinsäure     werden, wie im Beispiel des Patentes  Nr. 151191 (Zusatzpatent zum Hauptpatent  Nr. 149252) beschrieben, zum     4-Glykolyl-          aminobenzolarsin    reduziert;

   die erhaltene       wässerig-salzsaure    Lösung des     Arsins    wird  in eine Lösung von 58     gr        4-Oxy-3-amino-          benzolarsindichloridliydrochlorid    in 600     ein'       Methylalkohol und 900 cm?     1/2n    Salzsäure  eingerührt, über Nacht stehen gelassen und  das     Arsenobenzol    durch Abstumpfen mit Na  triumacetatlösung abgeschieden. Ausbeute  46     gr.  



  Process for the preparation of 4-glycolylamino-3'-amino-4'-ogy-arsenobenzene .. The subject of this patent is a process for the preparation of 4-glycolyl-amino-3'-amino-4'-oxyarsenobenzene, characterized in that 4-glycolylamino-benzenesine is condensed with 4-oxy-3-aminobenzene-1-dichlorarsine.



  The end product is a yellow powder that is easily soluble in dilute sodium hydroxide solution. It is characterized by low toxicity and high healing value.



  <I> Example: </I> 55 g of 4-glycolylaminobenzene-l-arsinic acid are reduced to 4-glycolylaminobenzolarsine, as described in the example of patent no. 151191 (additional patent to main patent no. 149252);

   the obtained aqueous hydrochloric acid solution of arsine is in a solution of 58 g of 4-oxy-3-aminobenzolarsindichloridliydrochlorid in 600 a 'methyl alcohol and 900 cm? 1 / 2N hydrochloric acid stirred in, left to stand overnight and the arsenobenzene deposited by blunting with sodium acetate solution. Yield 46 gr.
