Verfahren zur Herstellung von reinem Thornitrat für Gasglühlicht.
Eines der bekannten Verfahren zur Herstellung von reinem Thornitrat besteht darin, dass die nur mehr geringe Verunreinigung enthaltenden Rohthorverbindungen durch Behandlung mit Schwefelsäure in Sulfate verwandelt werden und diese auf dem Wege der fraktionierten Krystallisation von einander getrennt werden.
Vorliegende Erfindung besteht darin, dass anstelle der Schwefelsäure organische Schwefelsäureverbindungen insbesondere Alkyl- oder Ithylschwefelsäure verwendet wird, wobei bemerkt wird, dass die Anwendung der Äthylschwefelsäure zur Trennung der Ytheritund Cerelemente bekannt ist.
Die Verwendung der organischen Schwefelsäureverbindungen wie der Alkyl- oder Äthylschwefelsäure zur Herstellung des Thornitrates hat gegenüber der Verwendung der gewöhnliche !) Schwefelsäure den Vorteil, dass die folgende Trennung der gebildeten Thor-

Das auf diese Weise erhaltene Thoralkyl-(äthyl) sulfat wired hierauf in der üblichen Weise (Verwandeln in Hydrat und Lösen des Hydrates in Salpetersäure) in Thornitrat umgesetzt.
EMI1.2
Es können diese Effekte auch durch direkten Zusatz von geringen Mengen Alkyl- (resp. Äthyl) Schwefelsäure oder deren Salze zu reinem Thornitrat erreicht werden. Der direkte Zusatz hitt noch den Vorteii. dass die Zusatzmenge je nach Bedarf geändert werden kann.

Process for the production of pure thorn nitrate for gas incandescent light.
One of the known processes for the production of pure thorn nitrate consists in converting the crude thyroid compounds, which contain only minor impurities, into sulphates by treatment with sulfuric acid and these are separated from one another by means of fractional crystallization.
The present invention consists in using organic sulfuric acid compounds, in particular alkyl or ethylsulfuric acid, instead of sulfuric acid, it being noted that the use of ethylsulfuric acid for separating the ytherite and cerium elements is known.
The use of organic sulfuric acid compounds such as alkyl or ethylsulfuric acid for the production of thornitrate has the advantage over the use of ordinary!) Sulfuric acid that the following separation of the thor-

Sulfuric acid compound, for example dissolved in alkyl or ethylsulfuric acid and then by way of fractionated cry. tallization separated the thoralkyl or ethyl sulfate formed from the non-thoracic compounds.
The thoralkyl (ethyl) sulfate obtained in this way is then converted into thornitrate in the usual way (conversion into hydrate and dissolving the hydrate in nitric acid).
EMI1.2
These effects can also be achieved by adding small amounts of alkyl (or ethyl) sulfuric acid or its salts directly to pure thorn nitrate. The direct addition still has the advantage. that the additional amount can be changed as required.
EMI1.3
is converted into thr nitrate in the usual way.
