摘要:A process is described for the purification of lanthanide carboxylates which comprises a step in which the hydrocarbon solution deriving from the synthesis of lanthanide carboxylate, containing said carboxylate and impurities of the corresponding carboxylic acid and/or water, is treated with an aqueous solution of a base in order to obtain a pH of the aqueous phase ranging from 9.0 to 12.2 and/or a step in which the hydrocarbon solution containing lanthanide carboxylate is treated with a solid selected from Na 2 SO 4 , MgSO 4 , Mg(ClO 4 ) 2 , molecular sieves 3 â„«, molecular sieves 4 â„«, molecular sieves 5 â„« and molecular sieves 13 X. Analytical methods are also described, which allow the purity of the lanthanide carboxylates to be non-destructively measured.
