摘要: Molten salts have been used extensively as solvents for electrochemical processes. The difficulty of removing the last traces residual moisture from has often necessitated rather arduous drying procedures. If is not removed, hydrolysis occurs upon fusion. hydroxide ion thus produced precipitates metal ions, attacks glass, and reduced more easily than alkali metals, diminishing usable potential range soivent. It was found that if rigorously dried hydrogen chloride bubbled through melt twenty minutes before argon flush, impurity removed. (W. L.H.)
