  Verfahren zur Darstellung haltbarer Verbindungen von Wasserstoffsuperoxyd mit organischen Substanzen. 



   Den Gegenstand des Patentes Nr. 56829 bildet ein Verfahren zum Haltbarmachen der unbeständigen Verbindungen von Wasserstoffsuperoxyd mit organischen Substanzen durch Zusatz geringer Mengen fester organischer Säuren. 



   Es wurde nun gefunden, dass zum Haltbarmachen der im Hauptpatente bezeichneten Verbindungen organischer Substanzen mit Wasserstoffsuperoxyd nicht nur feste organische Säuren, sondern überhaupt Säuren aller Art angewendet   werden können. Kleine Mengen   sowohl organischer als auch anorganischer Säuren wirken stabilisierend auf die sonst   unbeständigen   Verbindungen ein. Von anorganischen Säuren ist besonders die Borsäure zweckmässig. Ebenso wie die Säuren selbst, wirken auch die sauren Salze organischer oder anorganischer Säuren. 



   Beispiel I. 



   450 g Harnstoff werden in 1000 g Wasserstoffsuperoxydlösung von   3000   H2O2 eingetragen. 



  Das (Gemisch wird dann auf 00 abgekühlt, der Kristallbrei wird abgesaugt und   nut     0#5 @ Bor-   säure innig gemischt.   Dann wu-d das Kristallpulver   bei 30 bis   top   getrocknet.

  Process for the preparation of durable compounds of hydrogen peroxide with organic substances.



   The subject of patent no. 56829 is a process for preserving the unstable compounds of hydrogen peroxide with organic substances by adding small amounts of solid organic acids.



   It has now been found that to preserve the compounds of organic substances identified in the main patent with hydrogen peroxide, not only solid organic acids, but all kinds of acids can be used. Small amounts of both organic and inorganic acids have a stabilizing effect on the otherwise unstable compounds. Of the inorganic acids, boric acid is particularly useful. Just like the acids themselves, the acid salts of organic or inorganic acids also have an effect.



   Example I.



   450 g urea are added to 1000 g hydrogen peroxide solution of 3000 H2O2.



  The mixture is then cooled to 00, the crystal slurry is suctioned off and thoroughly mixed with boric acid only. Then the crystal powder is dried at 30 to the top.
