Titanium peroxo compound

Patent Granted PROBLEM TO BE SOLVED: To provide a method by which an ammonium salt is efficiently removed to synthesize a low-ammonium type titanium peroxo compound in a short time and the yield is simultaneously improved. ; SOLUTION: The method for synthesizing the low-ammonium type titanium peroxo compound is characterized by adding an alkali metal compound such as an alkali metal salt of a carboxylic acid to an aqueous solution containing an ammonium type titanium peroxo compound and evaporating the resultant solution to dryness.
