Preparation method of calcium acetylacetonate

The invention discloses a preparation method of calcium acetylacetonate. The method adopts a dry method for preparation. Acetylacetone and calcium hydroxide quantitatively enter a special reactor. Asno solvent is used, the influence of the solvent on the functional complex is eliminated, the defects of long reaction time, low yield, many byproducts and the like of a liquid phase method are avoided, and the method has the advantages of high reaction speed, mild conditions, simplicity in operation, high selectivity, high yield, low energy consumption and the like. 本发明公开了一种乙酰丙酮钙的制备方法，该方法采用干法制备，乙酰丙酮与氢氧化钙定量进入特殊反应器，由于不再使用溶剂，消除了溶剂对功能配合物的影响，避免了液相法反应时间长、产率低、副产物多等缺点，具有反应速度快、条件温和、操作简单、高选择性、高产率、低耗能等优点。
