Abstract

PURPOSE: To recover solvent and complexing agent of usable quality, by dividing waste liq. formed in the preparation of Ziegler-Natta catalyst, where at least a hydrocarbon solvent and a complexing agent are used, into the solvent and the complexing agent through alkali-treatment and distillation etc., and by further treating the complexing agent through adsorption.
