A Study of the Reducing Action of Sodium upon Salts in Liquid Ammonia Solution.

Reactions of Inorganic Substances with Solutions of Metals in Liquid Ammonia.

“…Solutions of these compounds as well as solutions of the alkali metals other than lithium are remarkably stable in liquid ammonia at ordinary temperatures and in the absence of catalysts.3 Conversion of the alkali and alkaline earth metals to the corresponding amides nevertheless occurs slowly. This type of reaction is catalyzed by short ultraviolet light (73,128) and by a wide variety of metals and their compounds (5,6,9,12,13,14,27,30,85,145). In those cases in which compound catalysts are added, it seems likely that the compounds are reduced by the action of the metal solutions and that the reduction products are the active catalysts (57,127,146).…”

“…In addition to attack of the original halogenide or cyanide by alkali amide, the latter may act upon the product of the primary reduction reaction. For example, manganese formed by the reduction of manganese(II) iodide with sodium participates in subsequent reactions leading to the formation of Mn(NH2)2 and Mn(NHNa)2-2NH3 (30).…”

A New Method for the Preparation of Oxide Catalysts for the Carbon Monoxide Oxidation.

“…It is the purpose of this paper to develop in detail this new method for obtaining the oxides of nickel, cobalt, iron, manganese, and copper. Two procedures were used for the preparation of the finely divided, pyrophoric metals: (1) Preparation of the metallic amalgams and subsequent removal of the mercury by distillation (4); (2) Reduction of the metallic salt by sodium in ammonia solution (5).…”

Reactions of Solutions of Metals in Liquid Ammonia.

“…The physical properties and nature of solutions of metals (84, 150, 160, 179, 188) have been discussed in detail in this journal and elsewhere, as well as some of the general aspects of the chemical reactions which these solutions exhibit (37,151,186). However, the many known reactions of these solutions have never been brought together in one place so that the wide usefulness and great possibilities of such systems may be clearly realized by one not thoroughly familiar with this field.…”
