   Bisher konnte Schwefelwasserstoff durch Ferrisalze nur zu Schwefel oxydiert werden. 



  Es hat sich jedoch gezeigt, dass wider Erwarten beim Einleiten schwefelwasserstoffhältiger Gase in eine heisse, zweckmässig stark schwefelsaure Ferrisulfatlösung, wenn alternativ oder gleichzeitig die Regeneration des gebildeten Ferrosulfates durch Luft oder Sauerstoff erfolgt, die Oxydation zu Schwefelsäure ohne Abscheidung von Schwefel stattfindet.

Production of sulfuric acid.



   So far, hydrogen sulfide could only be oxidized to sulfur by ferric salts.



  However, it has been shown that, contrary to expectations, when gases containing hydrogen sulphide are introduced into a hot, suitably strong sulphuric acid ferric sulphate solution, if the ferrous sulphate formed is regenerated by air or oxygen alternatively or simultaneously, the oxidation to sulfuric acid takes place without the separation of sulfur.



   By blowing in air or oxygen or by oxidation in some other way, the ferric

 Understandably, the two reactions take place side by side and the regeneration does not differ in time. The sulfuric acid obtained in this way contains iron and can either be used as such or used to bind NH3, whereby, if
