Description |
La-Ce chloride, a mixed lanthanum-cerium chloride, represents a combination of rare earth elements commonly used in various industrial and scientific applications. |
|
Uses |
La-Ce chloride mixtures are utilized as catalysts or catalyst precursors in various chemical reactions, including in the production of petroleum products and in environmental applications such as automotive exhaust treatment. They are added to glass formulations to improve properties such as UV absorption, optical clarity, and color. |
| Production Methods | La-Ce chloride can be synthesized by directly combining lanthanum and cerium metals with chlorine gas at high temperatures. This process ensures the formation of pure chlorides. |
In this paper, the thermodynamic activity of two lanthanide chlorides (CeCl3 and NdCl3) in molten LiCl-KCl eutectic salt measured using open circuit potentiometry has been reported. Activity coefficient of CeCl3 was found to be strongly dependent on the concentration of CeCl3 in a concentration window of up to 4.66 mol % CeCl3. The activity coefficient of NdCl3 could not be measured due to the uncertainty in NdCl3/NdCl2 molar ratio in the salt, however the thermodynamic activity was measured relative to a 5 mol% Ag∣AgCl reference electrode.
The new enantiopure macrocyclic complexes [LnL]Cl3·nH2O or their racemic mixtures [LnracL]Cl3·nH2O (Ln=La+3, Ce+3, Pr+3 and Eu+3) have been synthesised in a template condensation of trans-1,2-diaminocyclohexane and 2,6-diformylpyridine.
