发明名称 Process for the preparation of iridium acetate
摘要 The present invention relates to a process for the preparation of indium acetate comprising the steps: (a) reacting an indium compound with an alkaline compound in a protic solvent to obtain an iridium containing precipitate, where the reaction is conducted in the presence of at least one component (i) selected from oxalic acid, a salt of oxalic acid, formic acid and a salt of formic acid, (b) reacting the precipitate in the presence of at least (i) one compound selected from oxalic acid, a salt of oxalic acid, formic acid and a salt of formic acid, and (ii) CH3CO2H and/or CH3(CO)O(CO)CH3 to give an iridium acetate containing solution. The invention also relates to indium acetate having a low halide content, to an indium containing precipitate and to uses of the iridium containing precipitate of the present invention and the iridium acetate of the present invention.
