  Verfahren zur Darstellung von festen Hydrosulfiten. 



   In   dem Patente Nr. 2861   ist n. a. beschrieben, dass man Salze der   hydroschwefligen   Säure in fester Form darstellen kann, wenn man wässerige Lösungen von Hydrosulfit mit Kochsalz sättigt. 
 EMI1.1 
 



   Beispiel. 



   Rine wässerige, etwa 30% ige Lösung von Natriumhydrosulfit wird unter Kühlung mit Ammoniakgas gesättigt. Hierbei scheidet sich Natriumhydrosulfit kristallinisch aus. 



  Man saugt dann so weit ab, dass eben noch eine dicke feuchte paste erhalten wird, welche direkt gebrauchsfähig und haltbar ist. Das Präparat besitzt die wertvollen reduzierendenEigenschaftendesHydrosulfits. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of solid hydrosulfites.



   In Patent No. 2861, n.a. described that you can prepare salts of hydrosulphurous acid in solid form if you saturate aqueous solutions of hydrosulfite with common salt.
 EMI1.1
 



   Example.



   Pure aqueous, about 30% strength solution of sodium hydrosulfite is saturated with ammonia gas while cooling. Here, sodium hydrosulfite separates out in crystalline form.



  It is then suctioned off so far that a thick, moist paste is obtained, which is immediately usable and durable. The preparation has the valuable reducing properties of hydrosulfite.
