Título (EN) PREPARATION OF SOLID, POWDERY RARE EARTH CARBOXYLATES BY EVAPORATION METHOD
(FR) PREPARATION PAR EVAPORATION DE CARBOXYLATES SOLIDES PULVERULENTS DE TERRES RARES
Resumo: front page image
(EN)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.
(FR)L'invention porte sur un procédé de préparation de carboxylates solides pulvérulents de terres rares, principalement de Nd, La, Pr et Ce, dans lequel les ligands coordonnés au métal sont des acides carboxyliques ramifiés à chaîne longue. Lesdits acides carboxyliques sont de préférence sélectionnés parmi les acides 2-éthylhexanoïque, néodécanoïque, versatique et naphthénique.
