Verwenden
Neodymium(III) chloride is used as a precursor for the production of neodymium metal. It is used as a catalyst and accelerates polymerization of various dienes such as polybutylene, polybutadiene, and polyisoprene. It has luminescence property and is widely used as fluorescent label in organic molecules, thereby helping in easy tracking of the compound using fluorescence microscope during various physical and chemical reactions.

Sicherheitsprofil
Poison by intravenous, intraperitoneal, and subcutaneous routes. Moderately toxic by ingestion. A skin and eye irritant. When heated to decomposition it emits very toxic fumes of Cl-.
Synthese
Method for preparing anhydrous neodymium chloride. Steps: (1)-(3) Neodymium carbonate reacts with dilute hydrochloric acid. pH is adjusted. Filtration, impurity removal, and microfiltration give a filtrate. (4)-(7) The filtrate is evaporated, cooled to crystallize, and centrifugally dehydrated to give neodymium chloride crystals. (8)-(11) The crystals are dissolved in pure water, re-concentrated, re-crystallized, and re-dehydrated by centrifugation to give purer crystals. (12) Stepwise isothermal dehydration: The crystals are heated stepwise in an oven at 80C, 110C, 150C, and 200C, holding at each temperature to gradually remove water of crystallization, yielding anhydrous neodymium chloride.
