PATENT-ANSPRUCH : Bei dem durch Patent Nr. 10510 gerschützten Kombinationsverfahren für die Darstellung von Schwefelsäure-Anhydrid der Ersatz des Eisenoxyds durch Kupferoxyd, Chrom- oxyd, Manganoxyd oder Gemenge dieser Oxyde bezw. durch deren hierbei sich bildenden Sulfate, um dadurch nicht allein die bekannte und für den Platinkontaktprozess erforderliche Reinigung der Röstgase zu erzielen, sondern auch durch teilweise Anhydridbildung im Oxydkontaktraum die Schwefeligsäuremenge der in den Ptatinkontaktraum eintretenden Gase derartig herabzudrücken, dass die Anhydridbitdung nahezu theoretisch, ohne Einschaltung EMI1.4 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: In the combination process for the preparation of sulfuric acid anhydride, protected by patent no. 10510, the replacement of iron oxide by copper oxide, chromium oxide, manganese oxide or mixtures of these oxides respectively. through the sulphates that form in this process, in order not only to achieve the known purification of the roasting gases required for the platinum contact process, but also to reduce the amount of sulfurous acid in the gases entering the platinum contact space through partial anhydride formation in the oxide contact space in such a way that the anhydride formation almost theoretically, without switching on EMI1.4 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
