Summary

Hydrogen sulfide is liberated when molten alkali thiocyanate reacts with ammonium salts or with salts of primary, secondary and tertiary aliphatic and aromatic amines. The mechanism of the topochemical reaction of ammonium salts is discussed. The reactivity of molten potassium thiocyanate permits the detection of organic bases. The application of the test in spot test analysis is described.

Zusammenfassung

Wenn geschmolzenes Alkalithiocyanat mit Ammoniumsalzen oder Salzen von primären, sekundären oder tertiären, aliphatischen oder aromatischen Aminen reagiert, wird Schwefelwasserstoff gebildet. Der Mechanismus der topochemischen Reaktion von Ammoniumsalzen wird besprochen. Dieses Verhalten des geschmolzenen Kaliumthiocyanats gestattet den Nachweis organischer Basen. Die Anwendung des Nachweises in der Tüpfelanalyse wird beschrieben.

Rêsumé

L'hydrogène sulfuré est libéré quand un thiocyanate alcalin fondu réagit sur les sels ammoniacaux ou sur les sels d'amines primaires, secondaires et tertiaires aliphatiques et aromatiques. On discute le mécanisme de la réaction topochimique des sels ammoniacaux. La réactivité du thiocyanate de potassium fondu permet la recherche des bases organiques. On décrit l'emploi du test pour la recherche à la touche.
