Abstract (en)
[origin: WO0228776A1] The additive compound of a carboxylic acid and a halide or of a rare earth or gallium halogenocarboxylate of the same acid is obtained by a method which consists in reacting with HX, X representing a halogen, and in a solvent selected among alkanes, cyclanes and aromatic solvents and their mixtures, a rare earth or gallium carboxylate, the reaction being carried out with an X/rare earth or gallium atomic ratio less than 3 when preparing a halogenocarboxylate. The second method of the invention concerns the preparation of an additive anhydrous compound of a rare earth or gallium halide and a nitrogen- or oxygen-donor compound which consists in preparing an additive compound of a carboxylic acid and a rare earth halide of the above type and in adding to the medium obtained a nitrogen- or oxygen-donor.
