  Application

  Acetylacetone was used in the preparation of Y₂0₃, La₂0₃ and La₂CuO₄ thin films.¹ Acetylacetone was used in the synthesis of the titanate/anatase dual-phase photocatalyst.²

  General description

  Acetylacetone is a β-diketone.³ It plays the role of chelating ligand and forms organometallic complexes which are used as gasoline additives, lubricant additives, driers for varnishes and printer′s inks, fungicides, insecticides, colors. Acetylacetone is a selective extraction reagent for molybdenum in ferrous materials.⁴ A drug complex has been crystallized from acetylacetone. Its X-ray crystal structure determination studies suggests that it contains one molecule of acetylacetone per asymmetric unit in the crystal lattice.³
