Subtitute Ammonias as Non-Aqueous Solvents

The striking similarities in solvent properties existent between ammonia and water suggest that certain substituted ammonias might also function as non-aqueous solvents for inorganic substances. On the basic of structural considerations alone, any such characteristics might be expected to be more pronounced with hydroxylamine hydrazine, and the lower acid amides than with the primary, secondary, and tertiary amines. Since hydroxylamine and hydrazine are strictly inorganic in nature, they should also be of more interest than the substituted ammonia containing organic radicals. Hydroxylamine, containing as it does both the amide and the hydroxyl radicals, should show solvent properties corresponding to those of both ammonia and water. Although data on the physical constants of these two compounds are incomplete, the values summarized. Early observation by Kohlschutter and Hofmann indicated rather striking resemblances between hydroxylamine and water in solvent character, salvation, amp

Nature of Metals Solution in Liquid Ammonia

Although the general behavior of metals in liquid ammonia has been treated in conjuction with the nature of the metallic state, a more comprehensive examinations of their characteristic appears warranted. Of many published summaries which describe such systems, those given by Johnson and Meyer and by Fernelius and Watt are perhaps the best for consultation because of their completeness and of their comprehensive coverage of the original literature. Of internet too are several less techical discussion. The alkali metals are readily soluble without appreciable thermal effects and without chemical reaction (in the absence of such catalysts as iron, iron (III) oxide, or platinum or of light of wavelength 2150 - 2550 A which favor amide formation) to give blue solutions which possess identical absorption spectra at given dilutions, and have densities less than the density of pure ammonia. Although the alkaline earth metals yield ammonates, their solutions of the alkali metals. It is no
