Title: PREPARATION OF SOLID, POWDERY RARE EARTH CARBOXYLATES BY EVAPORATION METHOD
Abstract:
A process for producing solid, powdery carboxylates of Rare Earths (RE) elements, among them mainly Nd, La, Pr and Ce, where the ligands coordinated to the metal are long-chain, branched carboxylic acids is provided. Preferably, the carboxylic acids are selected from the group consisting of: 2-ethylhexanoic, neodecanoic, versatic and naphthenic acids.
