Procedure
2.88 g of neodymium oxide containing 72.4% by weight of neodymium, 0.58 g of an aqueous solution of neodymium chloride containing 22.2% by weight of neodymium, 17.39 g of di(2-ethylhexyl)phosphoric acid (DEHPA) and 80 g of methylcyclohexane (MCH) are introduced into a reactor made inert beforehand with argon. The mixture is stirred and brought to 80° C. for 5 h. The mixture is cooled. Three washes with 20 g of water are successively carried out in order to remove the inorganic residues. Each wash comprises a step of stirring for 30 minutes and then a step of separating by settling out, also for 30 minutes, except for the final separating by settling out, which lasts 12 h. The water/MCH azeotrope is subsequently distilled with a Dean Stark apparatus. A clear solution of neodymium di(2-ethylhexyl)phosphate in MCH is thus obtained.
