  Verfahren zur Haltbarmachung von Wasserstoffsuperoxydlösungen. 



     Ks ist bekannt,   dass Wasserstoffsuperoxydlösungen, namentlich im verdünnten Zustande, sich   ohne   Zusatz grösserer Mengen von   Schwefel-Phosphor-oder Salzsäure   sehr leicht zersetzen. Da durch diesen Säurezusatz aber die Verwendbarkeit des Wasserstoffsuperoxyds stark eingeschränkt wird, versuchte man, ob nicht weniger schädliche Säuren.   vie bordure   oder organische Säuren, diese conservierende Eigenschaft hätten.

   Die meisten   organischen Säuren üben aber   keinen   conservierenden Einfluss   auf das Wasserstoffsuperoxyd aus Nur die   Essigsäure,   in grösseren Mengen zugesetzt, scheint bis zu einem gewissen Grade conservierend zu wirken ; aber auch sie vermochte die Mineralsäuren nicht zu verdrängen.

   Dabei wurde festgestellt, dass schon ein geringer Zusatz dieser Körper zu   Wasserstof'superoxydlösungen   die Zersetzung des Wasserstoffsuperoxyds wesentlich aufhält. So zeigt z. B. 3% Wasserstoffsuperoxyd, dem geringe Mengen Tannin oder Ratanhiagerb-

  Process for the preservation of hydrogen peroxide solutions.



     It is known that hydrogen peroxide solutions, especially in the diluted state, decompose very easily without the addition of large amounts of sulfur, phosphoric or hydrochloric acid. Since the use of hydrogen peroxide is severely restricted by this addition of acid, an attempt was made to determine whether the acids were not less harmful. vie bordure or organic acids have this conserving property.

   Most organic acids, however, have no conservative effect on the hydrogen peroxide. Only acetic acid, added in large quantities, seems to have a conservative effect to a certain extent; but even it was unable to displace the mineral acids.
 EMI1.1
   are known to have the property of absorbing large amounts of oxygen, especially in the presence of alkalis, the inventors investigated whether these bodies would also be able to counteract the tendency of hydrogen peroxide to split off oxygen.

   It was found that even a small amount of these bodies added to hydrogen peroxide solutions would substantially stop the decomposition of the hydrogen peroxide. So shows z. B. 3% hydrogen peroxide, the small amounts of tannin or ratanhiagerb-
