Description

  

  Verfahren zur Herstellung  von     2-äthylquecksilbermercaptobenzimidazol-ö-arsensaurem    Natrium.    Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Herstellung von 2-äthyl       quecksilbermercaptobenzimidazol-5-arsensau-          rem    Natrium, das dadurch gekennzeichnet ist,  dass man     Äthylquecksilberchlorid    mit     2-Mer-          captobenzimidazol-5-arsinsäure    umsetzt und  die so erhaltene Säure in das     Natriumsalz     überführt.  



  Die entstandene neue Verbindung ist leicht  löslich in Wasser und Methylalkohol, schwe  rer in Äthylalkohol und unlöslich in Äther  und Aceton. Sie soll als Arzneimittel und       Antiseptioum    verwandt werden.  



       Beispiel:     8,63     gr        2-Mercaptobenzimidazol-5-arsin-          säure    (erhalten nach Beispiel 1 der deutschen  Patentschrift Nr. 531801) werden in über  schüssiger Natronlauge gelöst und in eine  wässerige alkoholische     Aufschwemmung    von    7,93     gr        Äthylquecksilberchlorid    eingerührt  Es tritt völlige Lösung ein und beim An  säuern scheidet sich die quecksilberhaltige  Säure ab. Der Niederschlag wird abgesaugt,  gewaschen und mit Natronlauge vorsichtig       curcumaalkalisch    gemacht. Nach Filtrieren  wird die Lösung in Äther eingerührt.

   Das  sich hierbei abscheidende farblose     2-äthyl-          quecksilbermercaptobenzimidazol-        5-arsinsaure     Natrium von der Formel:  
EMI0001.0020     
    zeigt dieselben Eigenschaften in bezug auf  Löslichkeit wie die entsprechende     Sulfonsäure-          verbindung.  



  Process for the preparation of 2-ethylmercury mercaptobenzimidazole-ö-arsenic acid sodium. The present invention relates to a process for the preparation of 2-ethylmercaptobenzimidazole-5-arsenic acid rem sodium, which is characterized in that ethylmercury chloride is reacted with 2-mercaptobenzimidazole-5-arsic acid and the acid thus obtained is converted into the sodium salt .



  The resulting new compound is easily soluble in water and methyl alcohol, more difficult in ethyl alcohol and insoluble in ether and acetone. It should be used as a medicine and an antiseptic.



       Example: 8.63 grams of 2-mercaptobenzimidazole-5-arsinic acid (obtained according to Example 1 of German Patent No. 531801) are dissolved in excess sodium hydroxide solution and stirred into an aqueous alcoholic suspension of 7.93 grams of ethyl mercury chloride. Complete solution occurs on and when acidifying, the mercury-containing acid separates out. The precipitate is filtered off with suction, washed and carefully made curcuma-alkaline with sodium hydroxide solution. After filtering, the solution is stirred into ether.

   The colorless 2-ethyl-mercury-mercaptobenzimidazole-5-arsinic acid sodium which separates out has the formula:
EMI0001.0020
    shows the same properties in terms of solubility as the corresponding sulfonic acid compound.
