Preparation of Aluminum acetylacetonate: New distilled  acetylacetone dissolves in 40mL water. Dropping ammonia to acetyl acetone under stirring. The aluminum sulfate dissolves in water, and adding this solution to acetylacetone ammonia solution to produce precipitation. Controlling pH value is neutral during the reaction. Filtering, washing and naturally dry. Crude product is dissolved with a small amount of benzene, and filtering. Slowly dropping petroleum ether to the filtrate to produce precipitation. Filtering, washing with petroleum ether and naturally drying, then we can get the product.

Uses of Aluminum acetylacetonate: this chemical can be used as catalyst, crosslinker and glass coating. And it is also used as intermediate in organic synthesis.

When you are using this chemical, please be cautious about it as the following:
