Chemical Properties
off-white to pale yellow powder
Uses
Europium(III) chloride is used as a starting material for the preparation of other europium salts. It is also used in preparation of europium(II)chloride by reduction in a gold boat using hydrogen gas. Further, it is also used to prepare organometallic compounds of europium.
Uses
member of a family of moderate Lewis acids capable of acting as catalysts in selected oxidative and reductive processes,with particular utility in systems designed to exploit the chemistry of divalent and zerovalent reagents and organometallic intermediates.
Preparation
Europium Chloride, EuCl3, is formed as fine yellow needles by heating the hydrated chloride in a mixture of chlorine and sulphur monochloride.
Europium chloride was prepared by dissolving Europium(III) oxide in excessive 6 mol/L HC1, then hydrated europium chloride was obtained by evaporating away excess HC1 from the solution.
Safety Profile
Poison by
intraperitoneal route. Moderately toxic by
ingestion. When heated to decomposition it
emits very toxic fumes of Cl-. See also
