Abstract
High purity organometallic compounds can be obtained by the process which comprises subjecting an organometallic compound in a liquid state under stirring to preliminary oxidation or hydrolysis in a proportion of about 0.1 to 50% by weight of the organometallic compound to form solid reaction products, and separating by distillation the unreacted organometallic compound from the solid reaction products to recover the purified organometallic compound; and high purity metallic compounds such as a solid metallic hydroxide or oxide can be obtained by the process which comprises following the process as mentioned above, oxidizing or hydrolyzing completely the recovered purified organometallic compound.
