■ Bei der weiteren Ausbildung des in der Patentschrift 133457. beschriebenen Verfahrens zur elektrolytischen Darstellung von Hydroxylamin haben wir gefunden, dafs die elektrolytische Reduction der Salpetersäure zu Hydroxylamin nicht nur bei Gegenwart von Schwefelsäure, sondern auch von anderen sauren Elektrolyten,* wie z. B. Salzsäure oder Essigsäure, durchführbar ist.■ In the further development of the method described in patent specification 133457 For the electrolytic preparation of hydroxylamine we have found that the electrolytic Reduction of nitric acid to hydroxylamine not only in the presence of sulfuric acid, but also from other acidic electrolytes, * such as. B. hydrochloric acid or acetic acid, is feasible.

Beispiel:Example:

Der Kathodqnraum einer elektrolvtischen Zersetzungszelle wird mit 6 kg einer ca. 20 proc. •Salzsäure beschickt, der durch Diaphragma abgetrennte Anodenraum enthält 50 proc. Schwefelsäure. Beide Abtheilungen sind mit guten Kühlvorrichtungen versehen, im Kathodenraum ist ein Rührwerk angebracht. Als Kathode verwendet man zweckmäfsig Zinn oder auch eine indifferente Kathode unter Zusatz von ungefähr 10 g Zinnschwamm pro Liter Kathodenflüssigkeit; die Anode besteht aus Blei.The cathode space of an electrolvtischen decomposition cell is with 6 kg of an approx. 20 per cent. • Hydrochloric acid charged, the anode compartment separated by a diaphragm contains 50 per cent. Sulfuric acid. Both departments are provided with good cooling devices in the cathode compartment an agitator is attached. Tin or an inert cathode with the addition of tin is expediently used as the cathode about 10 grams of tin sponge per liter of catholyte; the anode is made of lead.

Man schickt nun unter starker Kühlung einen Strom von 60 bis 120 Ampere pro Quadratdecimeter durch das Bad und läfst allmählich 2 kg 50 proc. Salpetersäure in .dem Mafse zufliefsen, dafs stets eine eben deutliche Wasserstoffentwicklung an der Kathode wahrnehmbar ist. Im Uebrigen gelten die im Hauptpatent angegebenen Versuchsbedingungen.You now send a current of 60 to 120 amperes per under strong cooling Square decimeter through the bath and gradually runs 2 kg 50 proc. Nitric acid in .dem Adequate flow so that a just distinct evolution of hydrogen is always perceptible at the cathode is. Otherwise, the test conditions specified in the main patent apply.

Patent-Anspruch :
Abänderung des durch Patent 133457 geschützten Verfahrens zur Darstellung von Hydroxylamin durch elgktrolytische Reduction von Salpetersäure, dadurch gekennzeichnet, dafs man die Salpetersäure anstatt bei Gegenwart von Schwefelsäure bei Anwesenheit eines anderen sauren Elektrolyten der reducirenden Wirkung des Stromes unterwirft. 'Patent claim:
Modification of the process protected by patent 133457 for the preparation of hydroxylamine by electrolytic reduction of nitric acid, characterized in that the nitric acid is subjected to the reducing effect of the current in the presence of another acidic electrolyte instead of in the presence of sulfuric acid.
