Polarography in Liquid Ammonia above Its Critical Temperature

New Battery Electrolytes for Low and High Temperatures: Liquid and Solid Ammoniates for High Energy Batteries: I . Sodium Iodide and Lithium Perchlorate Ammoniates

“…By changing the composition, the upper limit can be moved up; thus LiCIO~ 9 xNH3 (x = i) is liquid at 200~ under a NH3 pressure inferior to 1 bar (7).…”

“…It is stable to photocorrosion in aqueous solutions when a thin film of oxide is formed and maintained at the semiconductor surface (2). Photoelectrochemical and photoelectrolytic cells employing p-InP have been reported with sustained performance and high efficiencies (3)(4)(5)(6)(7).…”

Polarographic Investigations in the Ammoniate of Sodium Iodide.

“…The spectrophotometric determination of formaldehyde with chromotropic acid has been described in many papers since the original observations of Eegriwe (5). By the same procedure or through the use of higher temperatures or longer heating times, many formaldehyde-releasing compounds give a positive purple color and thus can be determined (1,4)• A formaldehyde-releasing compound is defined as any organic compound which is hydrolyzed or oxidized in warm sulfuric acid under test conditions to give formaldehyde as one of the products. Other organic compounds, such as formic acid, can be reduced to formaldehyde (6) or, like methanol, can be oxidized to formaldehyde (ß) and then determined by the chromotropic acid procedure.…”

Polarographic Theory, Instrumentation, and Methodology

“…Hubicki and Dabkowska (71) investigated polarography in liquid ammonia above its critical temperature, utilizing the fact that lithium perchlorate with 4 moles of ammonia forms a liquid essentially stable at room temperature.…”
