High Temperature PVT Properties of Sodium, Potassium, and Cusium.

Abstract

it is not surprising that they respond similarly toward salt solutions. It appears that secondary amines may be slightly superior to the tertiary amines.Table II and Figure 5 show the results of a study which confirms the validity of the expression K = {K+ K .)12.Gradient quantities of adipic and oleic acid were added to diisopropylamine and equilibrated with 0.1% salt solution.These acids add foreign ions to the system and increase considerably the supply of amine ions.The adipic acid, being water-soluble, increases the supply of anions in the water phase, raising the sodium selectivity. The water content of the amine phase is reduced, probably through increase in the electrolyte content of the water phase. Oleic acid suppresses the sodium selectivity. The water content of the amine is increased, probably through solvation with the oleate ions. Although the individual ionic selectivities were affected radically, the mean selectivity was unaffected, except by the variation in water content. The results obtained with these acids agree with the other secondary amine data. ACKNOWLEDGMENTThe support of this work by the Office of Saline Water, Department of the Interior, Washington, D.

High Temperature Properties of Cesium.

“…All phases of this measurement program have been completed. The final properties of widium (2) and potassium (1) have been published in companion reports; those of cesium are presented in this report.…”

“…The possible significance of any thermal ionization in potassium and sodium vapors is discussed in the companion reports (1,2). It was shown that the degree of ionization to be expected in metal vapor may be obtained from its iorization potential (3).…”

“…(1), (2), and (3)) were derived from least-squares correlations. Al thermodynamic quantities in this report are arbitrarily based on Eq.…”

“…The imperfections which occur in the alkali metal vapors and the various treatmenth of these imperfections in the reduction of PVT data are discussed at some length in the companion reports (1,2). Quasi-chemical analyses of the PVT data for sodium and potassium have shown that dimeric and, perhaps, tetrameric molecules are present in the metal vapors.…”

An Analytic Study of the Transient Boiling of Sodium in Reactor Coolant Channels.

“…The equation of the straight line representing the particular property was then obtained graphically and used in the computer program. Later, data for sodium compiled by Tokar47 from a number of more recent literature sources became available and, [48][49][50] hence, were used to derive corrected equations for the various properties·. These corrected equations did not differ greatly from the original ones and, therefore, it was not necessary to repeat any of the calculations performed up to that time.…”
