The Detection of Small Amounts of Fluorine in Large Amounts of Chlorine (open access)

The Detection of Small Amounts of Fluorine in Large Amounts of Chlorine

Abstract: "Tests have been developed for both the qualitative detection and quantitative determination of fluorine in chlorine. The qualitative test is made by passing the gas through manganous chloride. If the pink solid tubes brown there is greater than 0.5 percent of fluorine in the gas. The quantitative test is a modification of the Steiger and Marvin Test with oxidized titanium solution."

Physical Constants of Uranium Tetrachloride (open access)

Physical Constants of Uranium Tetrachloride

Abstract: Exceedingly pure uranium tetrachloride was prepared for use in determining the physical constants of the compound. Measurements were obtained of the melting point and boiling point at pressures ranging from the triple point pressure to atmospheric pressure. Calculations were made of the vapor pressure equation for the liquid, the heat of evaporation, molar boiling point elevation, the vapor pressure equation for the solid, and the critical temperature.

Purification of Uranium Tetrachloride by Fractional Condensation (open access)

Purification of Uranium Tetrachloride by Fractional Condensation

"The effect of a single vacuum sublimation of contaminated uranium tetrachloride, with fractional condensation of the vapors, was investigated to determine whether a high degree of purity would result. It was found that this procedure was an excellent and simple method for obtaining exceedingly pure uranium tetrachloride."

Reactivity of Dibutyl Carbitol (open access)

Reactivity of Dibutyl Carbitol

Report discussing experiments to determine if the tri-ether (referred to in the report as dibutyl carbitol or carbitol) "was susceptible of a high degree of reactivity when used as an extraction agent for the removal of uranium from aqueous solutions."
