Abstract
A process is provided for preparing ceric carboxylates which comprises oxidizing cerous carboxylate with aqueous hydrogen peroxide in a two-phase system comprising an aqueous phase of hydrogen peroxide having a pH of at least 6 and an organic phase comprising a solution of cerous carboxylate in a water-immiscible hydrocarbon solvent at a temperature at which the reaction proceeds but below the temperature of rapid decomposition of hydrogen peroxide, thereby converting cerous to ceric ion and forming a solution of ceric carboxylate in the hydrocarbon solvent; heating the reaction mixture at a temperature at which any ceric-hydrogen peroxide complexes present are decomposed; and separating the organic phase containing ceric carboxylate from the aqueous phase of the reaction mixture.
