Summary:The invention discloses a new method for preparing platinum acetylacetonate, comprising the steps: taking water and platinous chloride, stirring so the platinous chloride uniformly disperses in water, heating under reflux, dropwise adding acetylacetone slowly, regulating the pH value to be 3-4 in the reaction process, heating and stirring after acetylacetone is completely dropwise added, regulating the pH value to be 9-10 with an alkali solution to accelerate separation of platinum acetylacetonate, continuing reaction, cooling to room temperature, washing with hot ethanol several times till the filtrate is transparent, combining the filtrates, and carrying out spin drying on the solvent to obtain yellow crystals, namely platinum acetylacetonate Pt(acac)2. The method adopts the platinous chloride and acetylacetone for synthesizing platinum acetylacetonate, the reaction conditions are mild, water is used as the solvent, and no pollution of organic solvents is caused. The method has the advantages of economy, en
