Abstract (en)
[origin: WO2019234356A1] The invention relates to a method for producing acetylacetonate from a hydrated or anhydrous chemical element Me, where the chemical element Me is selected from the alkaline-earth metals, the transition metals and the lanthanides, said method comprising a step of reacting, in an aqueous medium, Me oxide or hydroxide introduced in a solid form and acetylacetone, the acetylacetone being in excess compared to the Me oxide or hydroxide.
