Abstract
A method for recovering a titanium compound includes bringing a waste solution containing a titanium alkoxide into contact with a halogenating agent to convert at least a part of the titanium alkoxide to a titanium halide, and then distilling the solution containing the titanium halide to recover the titanium halide from the solution, or the method includes distilling a waste solution containing a titanium alkoxide and a titanium halide to recover at least a part of the titanium halide from the waste solution, bringing a residue in a distiller after the distillation into contact with a halogenating agent to convert at least a part of the titanium alkoxide to a titanium halide, and distilling the solution containing the titanium halide to recover the titanium halide from the solution. The method can recover an increased amount of a titanium compound from a waste solution containing a titanium alkoxide.
