title: Sodium tetrachloroferrate as a dehydrating agent.
abstract: Fused NaFeCl(4) shows a great affinity for moisture, which reacts chemically with it. By passage through a heated column filled with NaFeCl(4) coated on bioglass, gases such as nitrogen are found to have retained some moisture when dried over a molecular sieve. The compound also acts as a self-indicator, as the colour changes from yellow to brown after the reaction. It is more efficient than molecular sieves and is regenerated by passing HCl gas through the column.
