What is EUROPIUM CHLORIDE?

Chemical properties

off-white to pale yellow powder

The Uses of EUROPIUM CHLORIDE

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.

The Uses of EUROPIUM CHLORIDE

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.

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 RARE EARTHS.
