  Verfahren zur Darstellung von Wasserstoffsuperoxyd durch Destillation. 



   Im österreichischen Patente Nr. 67I75 wurde gezeigt, dass man aus festen   überschwefel-   sauren Salzen Wasserstoffsuperoxyd gewinnen kann, indem man diese Salze in der Wärme mit Schwefelsäure behandelt, die mit Wasser auf etwa   50%   verdünnt wird. Das so erhaltene Wasserstoffsuperoxyd enthält beträchtliche Mengen von Schwefelsäure, von der es durch Destillation abgetrennt werden kann. Noch vorteilhafter unterwirft man direkt das Gemisch von Schwefesäure und festem Persulfat der Destillation, wobei ziemlich konzentrierte Dämpfe von Wasserstoffsuperoxyd gewonnen werden können, und zwar nahezu während der ganzen Dauer der Destillation, wenn man diese in geeigneter Weise führt. Das Wasserstoffsuper-

  Process for the preparation of hydrogen peroxide by distillation.



   In the Austrian patent no. 67I75 it was shown that hydrogen peroxide can be obtained from solid supersulphuric acid salts by treating these salts in the heat with sulfuric acid, which is diluted with water to about 50%. The hydrogen peroxide thus obtained contains considerable amounts of sulfuric acid, from which it can be separated off by distillation. It is even more advantageous to subject the mixture of sulfuric acid and solid persulphate directly to distillation, in which case fairly concentrated vapors of hydrogen peroxide can be obtained, and indeed for almost the entire duration of the distillation, if this is carried out in a suitable manner. The hydrogen super
